HOME OF FUEL EFFICIENT GUARDOL® FE 10W-30
Lower viscosity Guardol FE 10W-30 is leading the industry with its new FA-4 formulation. It is proven to deliver up to 2% fuel savings while providing superior wear protection.
Wear protection that far exceeds Mobil Delvac
Guardol FE significantly outperforms Mobil Delvac Extreme FE 10W-30 in the DD13 Scuffing Test. And after 92 million miles of on-road testing and multiple engine tear downs, pistons and cylinder liners showed little to no signs of wear.
DD13 Scuffing Test Results
At 200 hours, Guardol FE 10W-30 showed no scuffing.
The DD13 Scuffing Test (ASTM 8074) was run at an independent lab using blind samples. This is a fired-engine test with all emissions controls, which runs for 200 hours or until scuffing is detected, whichever comes first.
Fuel economy to drive profits
With Guardol FE, Class 7–8 fleets can expect up to 1.5% fuel savings, and Class 6 fleets can expect even more, up to 2%.
