Last wedensday I left for P.A. and on my trip I averaged 29mpg full to empty (topped off).On the way home I avg 27mpg full to empty. This is with cone filter, old plugs, stock exhaust, new pcv valve, and averaging 75 mph.

i get about 15 mpg which really sucks cause i use nothing but 92-93 oct. fuel and its back up to 2.60 per gal. for the premium gas. i was used to paying that when reg. was that price so it don't seem too bad.

If your car isn't tuned for it and it wasn't knocking or anything like that on 87, you're just flushing money out the tailpipe for no gains.
