MOTY'S M103 10W40 FULLY SYNTHETIC ENGINE OIL 20L

10W-40 engine oil is a medium-viscosity oil suitable for a range of engines, especially older or higher-performance engines that operate at higher temperatures or have looser tolerances. It's a good choice for high-mileage vehicles, modified cars, and hot climates.

Suitable for:

Nissan Skyline GT-R (R32, R33, R34) — RB26DETT engines, especially in modified or high-mileage configurations.

Nissan Silvia (S13, S14, S15) — SR20DET engines under higher stress (e.g., tuned turbo setups).

Nissan 300ZX (Z32) — VG30DETT engines benefit from 10W-40 in warm climates or when tuned.

Toyota Supra (MK3, MK4) — 7M-GTE and 2JZ-GTE engines for heavy-duty or modified use.

Toyota Celica GT-Four (ST185, ST205) — 3S-GTE engines.

Toyota Altezza / Lexus IS200 — 1G-FE engines, especially with high mileage.

Mitsubishi Lancer Evolution (Evo I–IX) — 4G63T engines, especially in tuned or track-focused setups.

Mitsubishi GTO / 3000GT — 6G72 engines, particularly for older or heavily used vehicles.

Subaru WRX/STI (GC8, GD, GR) — EJ20 and EJ25 engines, especially for tuned or high-mileage examples.

Subaru Legacy GT / Outback XT — Turbocharged EJ engines.

Mazda RX-7 (FC, FD) — Rotary engines like the 13B-REW in hot climates or tuned setups.

Mazda MX-5 Miata (NA, NB) — Especially high-mileage 1.6L or 1.8L engines.

Honda NSX (Early Models) — C30A or C32B engines, particularly for high-performance or track usage.

Honda Prelude — H22A engines in older or heavily driven vehicles.

When Is 10W-40 a Good Choice?

1. High-Mileage Engines: Thicker oil can provide better sealing and lubrication in engines with worn internal components.

2. Modified Cars: Turbocharged, supercharged, or high-power applications that generate more heat and stress.

3. Warmer Climates: Offers excellent high-temperature stability in regions with consistently high ambient temperatures.

4. Track or Spirited Driving: Provides better protection under extreme conditions, such as high RPMs or extended track sessions.

When to Avoid 10W-40?

1. Newer Engines: Engines designed for low-viscosity oils like 0W-20 or 5W-30 may not perform optimally with 10W-40.

2. Cold Weather: Thicker oil can make cold starts harder in freezing temperatures.

3. Fuel Efficiency Priority: Higher-viscosity oil may slightly reduce fuel economy in daily driving.

If you're using 10W-40 for a specific JDM car or driving condition, ensure it aligns with OEM recommendations or the requirements of the engine setup (e.g., stock vs. modified). Let me know if you'd like tailored advice! 😊
