The Finest Wear Prevention For Dodge SRT and Nissan GT-R Engines

AMSOIL’s 100% synthetic base oil along with a powerful anti-wear additive package offers the best possible protection for ultra-high horsepower engines. AMSOIL 0W-40 delivers a potent film strength that buffers internal engine parts from severe shock loads, high heat and sudden acceleration.

Designed To Withstand Extreme Heat

High horsepower, turbo-chargers and super-chargers also bring extreme engine heat. AMSOIL 0W-40 is designed to resist shearing or boil-off, so the oil viscosity stays consistent for its entire service life. This trait also prevents oil consumption. AMSOIL engine oils are famous for consistent dipstick readings in engines that are in good mechanical condition.

Fast Cold Start Protection

While you may need an engine oil to withstand high-horsepower in the summer, if you have a Grand Cherokee SRT or a Ram with a 6.4L engine, you also may need protection during winter starts. AMSOIL 0W-40 Signature Series Synthetic Oil pours down to -51°C (-60°F). Therefore, engine oil reaches vital engine parts immediately upon start-up in cold weather. Fast oil circulation is certainly desirable in any weather for your SRT or GT-R engine.

Mixing AMSOIL Synthetic 0W-40 with Other Brands

AMSOIL 0W-40 Signature Series Synthetic Oil is compatible with all other brands of conventional, synthetic-blend and full-synthetic motor oils. While you can safely mix AMSOIL Synthetic Oil with other brands, this will reduce the drain interval and performance capabilities of AMSOIL 0W-40.

Service Life of AMSOIL 0W-40 Signature Series Synthetic Oil

AMSOIL 0W-40 Signature Series Synthetic Oil is overbuilt for long service interval capability.

For Supercharged or modified* engines:

• Up to 15,000 miles (24,000 km), 700 hours of running time or one year, whichever comes first.

For naturally aspirated engines (that are unmodified*):

• Up to 25,000 miles (40,000 km), 700 hours of running time or one year, whichever comes first.

* Engines operating under modified conditions (non-stock) are excluded from extended drain recommendations. Examples include the use of performance computer chips; non-OEM approved exhaust, fuel or air induction systems; and the use of fuels other than those recommended for normal operation by the manufacturer.
