So, over the weekend I drove home for deer season, well down in the Middle part of illinois our lowest grade fuel is 87, now when I went home (northern Illinois) their lowest grade was 89 at every station. I filled up on 89 down here (still cheaper than up there) and I noticed that my truck's response time when I press the gas pedal is amazing quicker.
So I guess my question is in the operators manual (My truck didn't have one when I bought it) what is the recommended grade for fuel that they specify?
Also my mpg's decreased about 8 miles per gallon. Just a side note.
