PRODUCT DETAILS ▾
Designed to meet the demands of modern engines, this high-performance engine oil is compatible with stock-grade W-40 specifications and offers reliable protection even under extreme operating conditions. With an allowable maximum temperature of up to 140°C, it maintains optimal viscosity and performance during high-heat operation. Its 100% synthetic formulation ensures excellent lubrication, reduced wear, and extended engine life, while advanced additives provide effective protection against LSPI (Low-Speed Pre-Ignition), making it ideal for turbocharged and high-performance engines.
Features
| Heat resistance | The rate of oxidation after the engine high-load. * |
| Oil film strength | High temperature high shear viscosity (High Shear Rate at 150°C). * |
| Resistance to high-temp deterioration | Degree of change in kinematic viscosity at 100 ° C after the high-load. * |
| Multigrade | Viscosity index. ** |
| Resistance to low-temp deterioration | Degree of change in kinematic viscosity at 100 ° C after the high-load. * |
| Oil life (Daily-use) | Ability to breakdown dirt (such as soot) and maintain oil performance. |
WHY WE CARRY THIS ▾
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT ▾
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
