The Nissan Skyline R33 GTR is an iconic machine known for its blend of raw power, precision handling, and all-around performance. Engine oil acts as the lifeblood of your RB26DETT engine, providing lubrication, temperature control, and protection against wear and tear.
In this post, we’ll take a deep dive into what makes the best oil for the R33 GTR, why it matters, and how to keep your engine running optimally.
R33 GTR Engine Oil
1. Motul 8100 X-cess 5W-40
Motul is a trusted name in performance oils, and their 8100 X-cess 5W-40 is a top pick for the R33 GTR.
This fully synthetic oil offers excellent high-temperature stability, which is key for turbocharged engines. It provides superior lubrication and protection, even under aggressive driving conditions.
Motul’s 8100 series is also known for its excellent shear stability, meaning it maintains its viscosity and protective qualities even after extended use.
This is particularly beneficial for those who track their cars or drive them hard on a regular basis.

2. Castrol EDGE 10W-60
For drivers who push their R33 GTR to the limits, especially during track days, Castrol EDGE 10W-60 is a solid option. This oil provides excellent high-temperature protection, making it ideal for hot conditions or engines that are consistently driven hard.
The 10W-60 viscosity ensures strong oil film strength at higher temperatures, which can help prevent engine wear when the engine is operating at extreme levels.
However, because of its thicker viscosity, it may not be ideal for daily driving in colder climates or during regular street use.
3. Royal Purple HPS 5W-40
Royal Purple is another highly regarded brand among performance car enthusiasts, and their HPS 5W-40 synthetic oil is a great match for the R33 GTR. This oil is formulated to reduce engine wear, enhance performance, and improve fuel efficiency.
One of the standout features of Royal Purple HPS is its advanced additive package, which helps to reduce friction and keep the engine running smoothly.
It also offers excellent protection against oxidation and oil breakdown, ensuring that it maintains its performance over long intervals.

Why Choosing the Right Engine Oil for the R33 GTR Matters
The R33 GTR comes equipped with the legendary RB26DETT engine, a 2.6-liter, twin-turbocharged inline-six that is highly revered in the world of high-performance cars.
This engine was built for power and speed, but it is also a precision machine that requires the right care to function at its peak. Proper engine oil ensures that all the moving parts in the engine are well-lubricated and protected, reducing friction and heat buildup.
In high-performance engines like the RB26DETT, oil does more than just lubricate; it also aids in cooling the engine, especially when you’re pushing the car hard, either during spirited driving or at the track.
Using the wrong oil, or one that’s not suited to the demands of this engine, can lead to excessive wear, oil breakdown, and ultimately engine failure.

Key Factors to Consider When Selecting Engine Oil for the R33 GTR
1. Viscosity
Viscosity refers to how thick or thin the oil is, which impacts how well it flows at different temperatures. For the R33 GTR, selecting an oil with the correct viscosity is critical, as this affects how well it can protect the engine under various driving conditions.
The RB26DETT engine typically performs well with a 5W-40 oil. The “5W” represents how the oil behaves in cold starts (lower numbers indicate better flow in cold conditions), while the “40” refers to its behavior at operating temperature.
A 5W-40 oil is thin enough to flow easily at startup, reducing wear during cold starts, but thick enough to provide adequate protection when the engine heats up.
For track use or high-stress conditions, some owners prefer a thicker oil, such as 10W-50, for added protection at higher temperatures.
2. Synthetic vs. Conventional Oil
When it comes to the R33 GTR, synthetic oils are the clear choice over conventional oils. Synthetic oils offer superior protection, better resistance to high temperatures, and more stable viscosity over time.
Given the RB26DETT’s turbocharged nature and tendency to run hot, synthetic oils are better equipped to handle the stress without breaking down.
Conventional oils can be more prone to viscosity breakdown and don’t handle the higher temperatures generated by the twin-turbo setup as well. In high-performance applications, the added cost of synthetic oil is well worth the investment for better protection and longevity.
Oil Change Intervals for the R33 GTR
Knowing when to change your oil is just as important as choosing the right oil. The RB26DETT engine can be sensitive to oil quality, especially given its high-performance nature.
Most experts recommend changing the oil in the R33 GTR every 3,000 to 5,000 miles, depending on how the car is driven.
- Daily Driving: If you’re using your R33 GTR primarily for street driving, you can stretch oil changes to around 5,000 miles, as long as you’re using high-quality synthetic oil.
- Track Use or Aggressive Driving: For those who take their R33 GTR to the track or regularly engage in spirited driving, it’s best to change the oil more frequently, ideally around every 3,000 miles.
- High temperatures and stresses can cause the oil to break down faster, meaning regular changes are crucial for maintaining engine health.

How to Check R33 GTROil Levels
- Park the car on a level surface and let the engine cool down for a few minutes after turning it off.
- Pull out the dipstick and wipe it clean with a rag or paper towel.
- Reinsert the dipstick fully, then pull it out again to check the oil level.
- The oil should be within the marked range on the dipstick.
- If it’s below the “low” mark, top up with the recommended oil.
Make sure you regularly check the oil, especially if you drive the car hard, as high-performance engines can burn oil faster than regular engines. If you notice the oil level dropping significantly between oil changes, it may indicate a leak or excessive oil consumption, which should be addressed immediately.
Signs of Oil Issues in the R33 GTR
- Oil Pressure Warning Light: If this light comes on, stop driving immediately. Low oil pressure can lead to catastrophic engine damage.
- Excessive Oil Consumption: If you find yourself needing to top up oil frequently, it could indicate a leak or internal engine issues.
- Oil Leaks: Any visible oil leaks under the car should be addressed immediately to prevent engine damage.
- Unusual Engine Noise: A knocking or ticking sound can be a sign of insufficient lubrication.
If you notice any of these signs, it’s important to diagnose and fix the problem as soon as possible.
