SMOIL SAE 20W-50 Synthetic Blend | Gallon

Born from the collaboration between Steve Morris Engines and Driven Racing Oil, SMOIL is a purpose-built race engine oil designed to protect and perform under the most brutal conditions. SMOIL SAE 20W-50 viscosity is intended for applications with large bearing clearances. Formulated specifically for boosted and high-horsepower engines, SMOIL delivers uncompromising lubrication and thermal stability for engines running on methanol, ethanol, and race gas. Its advanced additive package provides superior film strength, preventing metal-to-metal contact under extreme loads while resisting the fuel dilution common in alcohol-based fuels.

This unique blend gives racers confidence that their engines will stay clean, protected, and ready to make maximum power—pass after pass.
