Would this mat work for protecting concrete driveway from oils leaking from a vehicle?

We would not recommend using our 3/4" 4' x 6' Extreme Mats as a mat to protect your garage subfloor from leaking oil. Oil will actually cause the rubber mat to break down over time. If you would like a mat to protect your garage subfloor from oil stains, we recommend purchasing one of our Diamond Nitro Roll mats.
