Fuel recommended for Ford Flex - i.e. rental

Regular gas, and DO NOT run E85 in it.

Oops,double post!

No fuel filler cap! just a fuel door!!! so much for that idea. tell them to put in 87 and you have fun! :B

I was going to say - "What ever the filler cap says".

I yanked that flex fuel emblem off the back of my F250 and it now resides on the cowl of my Kawasaki Z turn mower just for grins.

If you use the cheapest fuel available it will be probably E85 and it will probably go thru that sucker like grass thru a goose. :B

Rental vehicle? Use the cheapest fuel they can find.

Big difference between a Ford Flex - which is a Ford Crossover model - and a Flex Fuel vehicle. The Ford Flex comes with three flavors of V6 engines.

Looking at Ford's specs I do not see it as being able to use anything other than gasoline - 35 of their models do have the capability but the Flex is not one of them.

A Flex Fuel vehicle is one which can use Ethanol as an alternative to gasoline.

It probably says "Unleaded Fuel Only" on the gauge or where you put the gas in. I would go with 87 octane.
