TDI Oil Specifications
idparts on July 15, 2014
505.00, 505.01, 507.00 – What do these mean? 10,000 mile oil change interval? Really? 5W-40, 5W-30, 0W-30, which is better?
Driving a VW TDI means questioning and sometimes tossing out some long-held beliefs about oil and oil change intervals (OCI). Pulling into your local quick-lube store and letting them put whatever’s in the drum below the floor into your car can be disastrous to your TDI. We’re going to try to make it simple and help you choose the oil your TDI requires.
Why is Correct Oil so Important?
If you drive a TDI you already know it’s a remarkable engine. Few, if any other engines offer a comparable combination of power, economy, and longevity. However, several aspects of the TDI’s design make it hard on oil.
First, the TDI’s high compression puts its piston rings very close to the point of combustion. Engineers soon learned that conventional oils could leave deposits, or coke, on the piston rings, which would jeopardize their function, increasing oil consumption.
Second, Oil is the life blood of a turbocharger. If oil cokes or gathers residue then it can clog the turbo oil feed line, starving the turbo of oil and ending its life. Not a good thing.
Third, newer TDIs (’04 and later) have injection systems that are generate very high fuel injection pressures but are also hard on camshafts. These cars require oil that can keep cam lobes lubricated in that high pressure environment.
Fourth, TDIs emissions systems have become much more sophisticated in recent years, requiring oils to be refined without components that can harm those systems.
Finally, all manufacturers are after maximum fuel economy and the longest possible oil change intervals in all their cars, and keeping oil in cars longer while providing the best possible fuel economy figures put additional demands on oils.
Oil Standards and Specifications
VW has established and tests oils to standards it has set for its engines. There are several other industry standards for engine oils, but for simplicity we’ve stuck with VW’s standards here along with oil viscosity measures that are commonly used in the US.
Will oils that do not meet or include VW standards work in your TDI? Probably. Oils that meet other standards such as ACEA or API may be fine for your VW. In fact, some owners purposely use oil that does not meet VW’s specifications because they believe it’s better for their TDIs than the ones VW certifies. Just keep in mind that VW may ask for proof that your car has used only oil meeting their standards in the event of a warranty claim.
Synthetic versus Non-Synthetic
This distinction is not as simple as you may think. Although all the oils that meet the standards in the chart above are considered synthetics, many of them may start with mineral oil base stocks, or esters. You’ll see terms like “synthetic technology,” or “pure synthetic,” on labels. But once again, if it meets the standard, it’s OK. And in the world of TDIs, if it meets the standard it is going to be synthetic oil.
Diesel Versus Gasoline
There’s a simple point here: Diesel engine oils have different requirements because, in part, of the need to keep soot in suspension in the oil between changes. You’ll notice that the oil in your TDI turns black very quickly after a change. That doesn’t mean it’s dirty, it is keeping the soot the engine generates in suspension. The presence of that soot is an oil design consideration. There are many oils that meet both gasoline and diesel standards, but beware of oils that are designed only for gasoline engines, even if they are synthetic.
Match the Rating to Your Engine
The table below lists the TDIs sold in North America and years they were sold, the oil they require, and some (not all) of the oil brands that offer oils that meet the standard.
|Model/Years||Engine Type/Code||Oil Standard||Suggested Brands/Weight|
|1996-1997 Passat1996-1999 Jetta||Rotary pump injection TDI, Codes 1Z, AHU||505.00||Castrol SLX Professional, Lubro Moly Synthoil Premium, Pentosin, Total Quartz Energy 9000, Mobil 1, 5W40, 0W40, 0W30|
|1999.5-2003 Golf, Jetta, New Beetle||Rotary pump injection TDI, Code ALH||505.00||Castrol SLX Professional, Lubro Moly Synthoil Premium, Pentosin, Total Quartz Energy 9000, Mobil 1, 5W40, 0W40, 0W30|
|2004-2006 Golf, Jetta, New Beetle2004-2005 Passat||Unit Injection, or Pump Deuse (PD) TDI, Codes BEW, BHW||505.01||Castrol SLX Professional, Lubro Moly Top Tech 4100, Pentosin High Performance II, Total Ineo MC3, 5W30, 5w40 Pennzoil Ultra Euro L|
|2009 and later Jetta and Golf TDIs; 2012+ Passat||Common Rail, Codes CBEA & CJAA & Passat code CKRA||507.00||Castrol SLX Gold, Total 504/507, Lubro Moly Top Tech 4200, Mobil 1 ESP, 5w30,|
The brands listed here are not exhaustive, there are others. And there are yet more oil brands that claim to be “designed for engines with 505.00 (or 505.01) oil requirements”, or words to that effect. Just keep in mind that if the VW standard isn’t printed on the label, the oil probably hasn’t been certified by VW. It’s your choice whether or not to use that oil.
What about 506.00?
VW has a 506.00 standard for oils that were considered good to use in cars that require 505.01 oils (PDs), and was also specified for the V-10 Touareg. This was a 0W30 weight oil that helped improve fuel economy. However, 506.00 oil was very expensive and did not match the lubrication or protective standards set by 505.01, and has been phased out. The Lubro Moly Top Tech 4200, a higher 507.00 specification oil, is also specifically approved for vehicles requiring 506.00 and 506.01.
What about Weight?
Europe and America use multiple viscosity ratings for oils. And there are a couple of trends in the oil industry when it comes to viscosity:
- Oil viscosity numbers are getting lower
- Lighter weight oils work better than they used to at high temperatures
Emissions and fuel economy requirements have, in many cases, driven manufacturers to use lighter weight oils. Since EPA measures include a cold start, light weight oil helps cars perform better in that test. Also, engine tolerances are much tighter than in past years. Thinner oil (especially when cold) can help provide lubrication during those first few critical seconds after a cold start. And today’s synthetics provide much better protection when hot than mineral-based oils did, even if their viscosity rating is lower. For example, 5W30 weight oil is considered fine for all driving conditions in PD and Common Rail TDIs, even in the desert in summer.
505.00 oils (for rotary pump TDIS) have the widest viscosity ratings of VW oils, and include 0W30 and 0W40. Although 5W40 oil is most popular in this category, many owners in cold climates like using 0W30 or 0W40 in winter.
And both 5W30 and 5W40 oils are available for oils meeting the 505.01 standard (PDs). Both are fine for use in all climates, although some owners prefer 5W40 over 5W30.
10,000 miles? Really?
All TDIs have a 10,000 mile oil change interval (OCI) after break-in. After generations of 3,000 mile OCIs many owners have difficulty accepting the 10,000 mile interval as safe. But 10,000 miles has proven to be a more than reasonable interval. Many owners run their oil longer. TDIs are proving to last many hundreds of thousands of miles without major wear using a 10,000 OCI with the correct oil, and many feel it’s wasteful to change it more often.
Soot build up is the primary reason for oil breakdown in diesels. As oil advances further technologically the different specifications have been increasingly tolerant of high soot levels in the oil. This results in many european vehicles with flexible service intervals to go 30,000 miles or more between oil changes.
Simple enough. If your car:
- Has a rotary injection pump, use oil that meets VW’s 505.00 standard
- Is a PD, use oil that meets VW’s 505.01 standard
- Is a Common Rail, use oil that meets VW’s 507.00 standard
For diesel and gasoline engines для какого двигателя
Those of you with an interest in the automotive industry may already be aware that diesel engines have greater compression ratios and provide more power than their gasoline counterparts, but you may be unaware as to why. While the main difference between diesel and gas engines lies in the timing of the fuel delivery system, this one difference produces far reaching consequences that allow the larger diesel engines of the modern era to operate with greater efficiency than gasoline models could ever provide.
Comparison of the Combustion Cycles of Diesel and Gasoline Engines
To understand the main difference between diesel and gasoline engines, it can be helpful to compare each of the four strokes that pistons in each engine type undergo. Both diesel and gasoline engines have intake, compression, ignition, and exhaust strokes in their cycles, and both are designed to ignite fuel and convert it to mechanical energy.
The following occurs in each engine type during each stroke:
- Intake stroke
The first downward stroke of the piston in both diesel and gasoline cycles. In a gasoline engine, both air and fuel enter the piston during this stage; if the system uses a carburetor, the air and fuel is mixed long before it reaches the chamber, while a port injected system injects the fuel outside of the piston just before entry. Diesel engines, on the other hand, allow only air to enter the piston during the intake stroke.
- Compression stroke
The upward motion of the piston compresses the contents of the cylinder at this stage. Since it is highly undesirable for the mixture of air and fuel in gasoline engines to spontaneously ignite, the compression ratios of gasoline engines must remain much lower than diesel engines, where the compressed air is heated in excess of 540 degrees Celsius during each compression stroke.
- Ignition stroke
In gasoline engines, the mixture of compressed air and fuel is ignited during the downward stroke of the piston with the help of a spark plug during the ignition stroke. Conversely, diesels engines use direct fuel injection to inject a fine mist of fuel into the cylinder during the beginning of the ignition stroke; because of the high temperatures within the diesel cylinder, the fuel spontaneously ignites without the help of a spark plug.
- Exhaust stroke
There is no appreciable difference between diesel and gasoline engines during this upward and final stroke of the combustion cycle, as the exhaust is simply forced through the exhaust valve in both engine types at this stage.
Higher Compression Leads to Greater Power and Fuel Efficiency
The effects on power that the higher compression ratios in a diesel engine are able to achieve are impressive. Because gasoline engines use lower compression to prevent the spontaneous ignition of fuel and air which creates excessive heat and leads to engine knocking, their compression ratios range from 8:1 to 12:1. Diesel, on the other hand, relies on the higher temperatures achieved with greater compression ratios to ignite the fuel; the ratios for these engines range from 14:1 to 25:1.
Greater compression translates into greater amounts of power available to do mechanical work, but it also translates into more efficient use of fuel. In addition, diesel fuel itself contains a higher amount of stored energy per gallon when compared to gasoline. These two factors combined allow diesel engines to deliver the improved mileage they are known for when compared to equivalent gasoline models.
Glow Plugs or Computer Control Solve Diesel Cold Starting Issues
Because the compressed air within diesel engines must obtain a temperature high enough to spontaneously ignite fuel, diesel engines typically need help to achieve those temperatures when starting cold. Traditionally, diesel engines used glow plugs, or electrically heated wires, to heat the interior of each cylinder enough to allow the engine to start. In the larger, more advanced diesel engines of today, computer control delays the timing of fuel injection during cold weather to allow greater compression of the air within each cylinder, creating more heat and allowing the engine to start without the help of glow plugs.

October 25, 2020:
Despite what marketing from major companies likes to try and make us believe, there isn’t a lot of innovation in motor oils from year to year. Because of that, there weren’t a lot of changes that needed to be made to the selections on this list. Now, we aren’t saying that over time new formulas aren’t created that help to better extend the service life of engine components, it is just that it doesn’t happen quickly or very often. We also like to see a formula proven for a while, rather than just taking a company’s word that their newest product is automatically the best, which is why we stuck with most of our previous recommendations during this update.
One notable change to our diesel oil rankings was replacing Total Quartz 9000 Energy with Total Quartz Ineo. The former was designed for engines without particulate filters, and since many jurisdictions are no longer allowing vehicles without them, we thought it better to include the Ineo series. While it is specially formulated for the needs of German engines, it does meet the technical requirements of diesel vehicles from General Motors, Hyundai, and Kia, too.
Though many oils are suitable for a variety of engines, it is generally best to use them in the kinds they are designed for. So, while Total Quartz Ineo could be used in heavy old trucks, it performs best in modern multi-valve engines quipped with turbochargers and direct injection technology. The same goes for Lucas Magnum CJ-4. While it could certainly serve well in enough in a light-duty passenger car in a pinch, it is best reserved for heavy-duty trucks. Similarly, though Chevron Delo 400 XSP won’t harm a gasoline engine, you would be better off using something from our synthetic oils list that was specifically designed to handle the different environment found inside of a gasoline engine.
August 16, 2019:
Diesel engine oil comes in a variety of different formulas, and while they will all lubricant your engine components, some perform better under certain conditions than others. For example, Rotella T6 5W-40, Valvoline Premium Blue Extreme, and Mobil Delvac 1300 Super offer good thermal stability, allowing them to perform well in both hot and cold climates with as little change in viscosity as possible.
Castrol Edge C3 Advanced Full Synthetic, Motul 8100 X-cess, and Lucas Magnum CJ-4 will excel in hot conditions, such as those found in high-performance engines or tow vehicles that undergo a lot of strain. These formulas are designed with high thermal breakdown resistance and/or good oxidation stability.
When it comes to cold climates, Pennzoil Platinum Euro L and Total Quartz 9000 Energy are both good choices, as they retain decent pumpability in below-freezing conditions. This means cold starts will cause less damage over time, hopefully extending the service life of your engine.
Another thing to consider is synthetic versus mineral-based oils. While these terms may be slightly misleading, as the truth is they are both made from crude mineral oil, synthetics undergo a more advanced refining process that results in a cleaner, higher purity lubricant. This translates to a longer service life inside the engine and less buildup of sludge and other impurities. As you might expect though, this generally makes them more expensive. Items one through eight on our list are all full synthetics. The number nine product, Total Quartz 9000 Energy, is a mineral and synthetic blend, and the number ten item, Mobil Delvac 1300 Super, is made from all mineral base stocks, which is why it is the most budget-friendly option.
Now, just because you have bought a top-quality diesel oil that promises superior performance from of your engine doesn’t mean that you should necessarily stop there. You may be able to see even more increased performance, better gas mileage, and lower engine wear by using an oil additive.
Diesel vs. Gasoline Engines
Diesel engines and gasoline engines are the two types of internal combustion engines (ICE) widely available on the car market today. These engines differ from each other in one crucial way: how fuel is exhausted in the engine.
In a gas engine, gasoline and air are compressed. At the critical pressure point, the car’s spark plug ignites this mixture, turning it into energy for your car. Diesel engines do not utilize these spark plugs. When air and diesel fuel are squeezed tightly enough, they are able to combust on their own. This is where we get the term compression ignition. All diesel engines function through compression ignition. It is possible for a gas engine to start through compression, but this can incur a great deal of damage. On the other hand, diesel engines are designed for this type of ignition.
So how does this all relate to you? You may not be a mechanic, but you’re wondering how these two engines will affect your driving experience and your bottom line. Here are some things to consider when comparing a gasoline and diesel engine car.
Diesel fuel costs more at the pump than gasoline, but diesel provides more bang for your buck in terms of energy output. Because of this, most diesel vehicles tend to get 40 or 50 miles per gallon. Overall, the gas cost is likely going to be about the same. Factors like vehicle type and driving style will affect your bottom line, but your gas costs are likely to come out relatively similar whether you’re using a gasoline or diesel engine.
Horsepower and Torque
The power output of gasoline and diesel engines are measured in two different ways: horsepower and torque. Horsepower measures the car’s overall power while torque measures the car’s ability to accelerate and adjust while driving. Because of this, having a lot of horsepower and a small amount of torque will hurt your vehicle’s acceleration. Torque gets heavy loads going, and that’s why we see diesel engines used in big trucks. On the other hand, diesel engines don’t rev up in the way that gasoline engines do. They produce less horsepower than gas engines. For this reason, race cars are built with gas engines to maximize horsepower.
Research over the years has shown that consumers are generally more concerned with torque than horsepower. Most people are looking for fast acceleration and adequate towing ability in a car.
Diesel engines are typically more reliable than gas engines due to their natural build. They rely on compression ignition, the ignition that gasoline engines can’t withstand for long. They are built tough and tend to require little maintenance. Historically, this has caused diesel engines to weigh much more than gas. Due to advancements in manufacturing, this added weight has been reduced quite a bit. Today’s diesel engines still outweigh most gasoline engines, but the difference has shrunk over the last ten years.
Additionally, diesel engines are more simple in design due to not having spark plugs or the attached electrical wiring. Generally speaking, diesel engines can travel many more miles and run for several hundred more hours before they require their first major service.
Engines: Diesel, Gasoline, and Natural Gas
Internal combustion engines convert energy from a variety of fuel types into useable mechanical energy that drives movement in the engine’s pistons. The linear motion of the pistons facilitates the rotary motion of a crankshaft, which turns wheels or propellers and enables motion in vehicles. Diesel engines are built to provide enduring, fuel-efficient power in a wide range of applications, making them one of the most popular types of internal combustion engines.
At Central Diesel, we provide diesel engines, generators, railroad equipment, associated parts, and automotive parts services to keep your equipment running at its optimal potential. We maintain a comprehensive parts warehouse for diesel engines and systems to facilitate quick delivery of any critical part or component you need to keep your diesel equipment operational.
Different Types of Engines
Engines are most commonly differentiated by their fuel type. The three main types of fuel (and the engines that use them) are as follows:
Each power source carries its own strengths. All three types of engines are common internal combustion engines that use ignited fuel to push pistons up and down.
A gasoline engines require a spark plug to facilitate the initial ignition. Natural gas engines also use a spark plug. Diesel engines achieve the same effect through compression. Diesel is also one of the safest fuel sources in terms of storage and handling.
Uses and Applications
Many commercial and industrial operators prefer diesel engines because diesel is an energy packed fuel source. Diesel compresses air at nearly twice the rate of gasoline in the pistons which means greater efficiency and power. Because of that dense energy, diesel engines can effectively move large vehicles such as:
- Tractors and large agricultural equipment
- Marine vessels
- Large locomotives
As automobiles decrease in size and power, they will be widely available with both gasoline and diesel engine options. While natural gas is often considered a greener source of energy, it hasn’t really caught on due to lower fuel efficiency, increased safety concerns and higher maintenance costs. As such, diesel remains the powerhouse of engine types when the application requires efficient, consistent performance.
Avoiding Diesel Engine Problems
Regular preventative maintenance provides the best way to keep diesel engines performing in peak condition. The fuel injection directly impacts the engine’s efficiency, so regular inspections are essential to make sure it functions as expected. Catching oil leaks and exhaust problems early on mitigates the risk of damage and extends the life of the engine and the vehicle.
Incorporate these steps into your maintenance routines for longer, better engine performance:
- Maintaining the oil system. Stay on top of regular oil changes to clean out your engine system. Also, trace oil leaks to their source to better monitor developing problems.
- Checking and changing filters. Diesel engines need consistent air flow and oxygen to power the pistons. Dirty filters, especially in boats, can restrict airflow to a point where the vehicle becomes inoperable.
When the check engine light turns on, significant engine damage might already be underway. Central Diesel provides diagnostic and repair services to restore your diesel engine back to working order. We also replace malfunctioning parts in your vehicle’s hydraulic, exhaust, and fuel injection systems.
Engines — Frequently Asked Questions (Faqs)
- If my engine is used very rarely during the year (less than 150 hours), how often should I perform maintenance on it?
You can perform maintenance on the engine every two years with less than 150 hours of operation per year. However, you should replace the fuel filter every year and ensure you are using some type of additive in the diesel fuel to eliminate any potential problems in the future.
- What is the compression difference between a gasoline engine (spark ignited) and a diesel engine (compression ignited)?
On average a gasoline engines compression reading per cylinder is 140-220 PSI. On a diesel engine it would be 350-450 PSI. The wide variance in the readings is dictated by whether the engines fuel system is direct injection or indirect injection.
- When looking at specifications on an engine, what is more important, horsepower or FT/LBS of torque?For most automotive applications, horsepower seems to play a major role in consumers making a decision on a vehicle. For heavy construction, FT/LBS of torque is the lead indicator in determining what engine is needed. Torque is the net power/energy that the engine produces to perform a task.
- Does ambient temperature affect an engine’s performance?
Yes, the performance of any engine is affected by barometric pressure, temperature and humidity. Have you ever noticed that you achieve higher MPG on a vehicle in the winter, than you do in the summer months?
- Which engine is more efficient when it comes to energy produced, gasoline or diesel?
Gasoline engines are less efficient (32-38%) compared to a diesel engine (42-46%), due to diesel produces more torque (energy) per combustion cycle. A diesel vehicle has better MPG compared to gasoline vehicle and can go farther on a tank of fuel.
