What grade gas do you put in a v6 mustang
When I first purchase the car , I was to the put 89
because of a knocking sound when I turn over the
car which I came to realize it's a common problem ,
but when I search I don't get a result or answer
Put in 87 octane unless it pings. If it is pinging there is an issue with it that needs addressed. How many miles on your Mustang?
137000. It only backfired when i started it up thismorning and just took off and only did it once. I have2007 fastback no mods just stock v6. I been using 89 and 91 gas. Had car for a week.
