Frequently Asked Questions
What vehicles use 10W-30 motor oil?
10W-30 is commonly used in older domestic vehicles, classic cars, and some trucks. It provides a thicker oil film for engines with looser tolerances. Check your owner's manual to confirm.
Why does 10W-30 have the lowest NOACK volatility?
The 10W-30 formulation uses heavier base stocks that resist evaporation. With just 4.1% NOACK volatility, it means less oil is lost to evaporation during high-temperature operation, reducing oil consumption between changes.
