Chasetomasi Posted July 15, 2023 Share Posted July 15, 2023 Does anybody with the 3.0 run e85 or any alternate fuel or is that even a thing for these cars? I’m looking to make the most out of the car but I haven’t seen anything about e85 or seen any flex fuel kits online. Quote Link to comment Share on other sites More sharing options...

If you are referring to the 3.0T engine in the 2017+ MKZ's? No, do not use E-85 fuel. The engine is not E-85 compatible. Good luck.

Good luck. like bbf said, look at the warnings in the fuel section of your manual. If somehow you have a yellow fuel filler fitting "gas cap equiv." that says E85, it's the wrong one and should be replaced with the OEM. The 400hp 3.0 turbo shouldn't even be run on regular E10, only midrange or premium E10 or if available, non-alcohol. Quote Link to comment Share on other sites More sharing options...
bbf2530 Posted September 6, 2023 Share Posted September 6, 2023 (edited) Hi gang. 17MKZ3.0TT offered good information above. However, just to avoid confusion: Our MKZ engines are designed to run on fuel with a minimum octane of 87, and containing up to 15% ethanol (E15). They will get full advertised power using 93 octane, but will only suffer a loss of ~ 20-25 horsepower using 87 octane. And using 89-91 octane mid-grades will offer correspondingly lower ratio losses of horsepower than 87 octane. Full gas, non-ethanol fuels can be hard to find in many parts of the country, so have no worries about using E-10 fuels, or up to E-15, if it is all that is available. More important than octane (other than minimum 87) is to use good quality fuels. So try to only use Top Tier fuels from name brand stations, avoiding cheap, generic gas stations whenever possible. Essentially, if you really need full advertised power, use Top Tier, 93 octane fuels. If not, and you can get away with 375-380 horsepower in your daily drives, use 87 octane, save money and rest easy. Personally I use Top Tier, 87 octane fuel 95%+ of the time, unless I'm feeling a bit sporty. But then again, I do not drive my MKZ hard at all. All of the above being said, I would still recommend everyone read their Owners Manual section concerning correct fuels to use. Just look in the Index under "Fuel Quality" for the correct pages in your copy. Feel free to ask any questions, and good luck.
