just curious..did u even try to run 87 in there? i ran 87 in my gsr and never had any problems..at worse i got 28mpg at best 32mpg..true story and no knocking, no nothing
No. I've thought about mid-grade though. I've heard so many people say not to run anything besides premium that i've never tried. It gets decent mileage like your saying with local driving, but going to work and school gets bad mileage for me.Originally Posted by PBS
