If it is a flex fuel vehicle you can burn all you want.
If not a flex fuel vehicle immediate damage can result. The Ethanol will damage the seals in the fuel system.
Only vehicles that are Flex Fuel vehicles can burn E85. How many there are is of no consequence.
Yes. An E85 car is called a Flex Fuel car meaning it can burn regular gasoline or E85.
No, you cannot use E85 or above in any engine not designed for that fuel. You will damage the engine if you do.
I don't think that is possible sorry
NO! As far as I know the Vibe is NOT a Flex Fuel vehicle. If it is Flex Fuel and can burn E85 it will have a label affixed to the vehicle somewhere. Do NOT use E85 in a non Flex Fuel vehicle.
Yes, it will destroy a diesel engine.
Maybe, if it is a 2.7L and there is a E85 sticker inside the gas door. If not no, it would damage the fuel system.
If is says FlexFuel in your owners manual or on the rear of the vehicle then you can burn E85. If not, then no you cannot use E85.
If the car is a Flex-Fuel vehicle then yes you can use E85. If it is not a Flex-Fuel vehicle you cannot use E85. Using E85 will damage components. As far as I know your 2006 Pontiac G6 is not a Flex-Fuel vehicle. Reads your owner's manual to be sure.
If there isn't a sticker on or near the gas cap that says E85, or flex fuel it is not recommended to run E85. A 10% mixture that is sold at most gas pumps is ok.
No, it will damage the fuel system.
Yes you can, but I recommend max 60 % e85 and 40 % petrol. Be aware that e85 may "kill" your filter. so change that one first.
