you can try looking on google for an answer.


Should NOT be able to, but what's the 8th digit of the VIN to be sure


what dose the vin have to do with anything?


actually the vin has all the information about the car :) u can tell paint color manu dates and what fuel types are acceptable.


no! do not run E85 unless it is specified on your vehicule, it'll say something like flex fuel or bio fuel acceptable, either way I would not run it period, its not good on your engine, and its over all a terrable fuel supply.
