Using Mobil 1 in a Mazda Rotary Engine
I have a 2005 Mazda RX-8. This has a rotary engine, which injects oil into its intake path. Can I use Mobil 1 without risk of incomplete oil burn and or buildup?
-- Matt Hejnas, Central Valley, NY
Mazda does not recommend the use of synthetic oils in its rotary engines. To help maintain your vehicle's warranty coverage, we suggest that you follow your car builder's engine oil recommendation.
