According to the 1999 Mercury Grand Marquis Owner Guide :
It is NOT a flex fuel engine ( use " regular " unleaded gasoline , 87 octane )
No. A 1999 Ram is not equipped to run on E85.
If you mean E85, no.
If you are referring to E85, from my experience using E85 actually lowers the fuel economy.
No, is the short answer. Only with modifications to certain hoses and components. Owner's manual list the fuels that can be used.
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.
NO , your vehicle is designed to run on " regular " unleaded , 87 octane
No ( according to the 1999 Ford Expedition Owner Guide your vehicle is designed to run on " regular " unleaded gasoline , 87 octane )
No. do not use E85 in a Liberty. It does not have the proper software or fuel system components to run on E85.
I don't believe so , 1999 was the first year that Ford Rangers offered the 3.0 L FFV engine option that allowed you to run E85 or regular unleaded 87 octane , or any combination of the 2 fuels
Yes. An E85 car is called a Flex Fuel car meaning it can burn regular gasoline or E85.
E85 is 85% ethanol alcohol and 15% gasoline. A change in either the price of oil or the price of the corps used to make the alcohol for E85 will result in a change in the cost of E85.
I dont think so but if you stop into any gas station that sells e85 they are supposed to be able to tell you. How ever your not going to save much $$ doing so even if you can because you will not get as much mileage with e85 as you do with regular gasoline.
