I used "restore" on an old ford escort and it worked! I couldn't believe it. I don't put much faith in things like that but I figured the car was junk anyway. It had no power and after the restore it made a big difference. I think on your car with 80,000 miles, its probably something small like fuel filter, plugs, injectors or something like that. That escort was well over 200,000 miles. I would not used restore on a newer lower mileage car. I would use the seafoam or gumout.
