CarCat Posted August 31, 2019 Report Share Posted August 31, 2019 I just bought a 2008 Ford Edge Limited from the original owner/private party. I know nothing about the Edge. Engine is V-6 3.5L . Owner's manual specifies to use 87 octane unleaded gasoline. However, the gas cap has an E85 label stuck on it. Do I ignore this E85 label and follow the owner's manual?

onyxbfly Posted August 31, 2019 Report Share Posted August 31, 2019 (edited) Welcome to the forums! I would reach out to the seller and ask him which type of gas they used etc. I do not recall any of the edge models to be flex fuel compliant. The previous owner may have performed a conversion. Or when in doubt if the vehicle has a E85 sticker it should run fine on normal gas till you are able to get a definitive answer from the previous owner.

Gadgetjq Posted August 31, 2019 Report Share Posted August 31, 2019 The gas cap might have been replaced with one from another vehicle. I'd go with the manual's recommendation. 2 Quote Link to comment Share on other sites More sharing options...
akirby Posted August 31, 2019 Report Share Posted August 31, 2019 That engine is not flex fuel. Do not use E85. 1 Quote Link to comment Share on other sites More sharing options...
CarCat Posted August 31, 2019 Author Report Share Posted August 31, 2019 Thank you, one and all. You've given me the answers. I'll stick to the owner's manual. 1 Quote Link to comment Share on other sites More sharing options...
