Re: What grade fuel do you use?????
I've been using 87 in my 07 TRD SE with the best mileage to date at 19.7 driving real conservative. My mixed mileage is around 18. I have noticed slight pinging a few times mostly when pulling my trailer and I just top it off with the expensive stuff and it takes care of the pinging right away. My mileage was less until I got the engine good a broken in too.
