Please help I have a 1992 Jaguar xj6 and yes its a 4.0 litre but it is wasting way too much gas. Even when I sit in the car idling and not traveling I can watch the gas guage go down. It cost me 30 dollars to drive about 60 kms. I have checked and there are no leaks anywhere. I dont have money to fix all the problems I just want to drive it till it dies. Would changing the feul filter, o2 sensor or fuel regulator be the best way to get better gas milage? Also those high octane aditives didnt help either. Any help appreciated. This car wasnt running when I got it and with the help of this site it now drives great, just wastes way too much gas.
have the same problem?
