I currently use 93 octane gas, sometimes 91 depends on price and where I am when I fill up. Ive been getting no better than 20-22 mpg. I dont push my car often b/c the weather has been bad, but I drive basically to work and back. I drive in 6th gear at like 50-60 mph on my daily commute. Is this normal? Any ideas I feel like I should be getting better mileage...what do you all get?

 

These gas mileage threads are getting crazy...

im like 24-25....mostly in town, sometimes more, sometimes less..

 

I usually get around 25, but the majority of that is highway miles and when I am in the city I rarely go over 3 or 4k RPMs.

 

I get around 25mpg mixed city/hwy

 

Going like 65 is close 4k rpm is there a way to get my 6th gear opened wider so the rpms are lower?

 

65 is not 4K in a stock car there bud.

Anyways i get about 25-27 mixed.

I did however get 22-25 when the car was completely stock, i now have intake, test pipe and exhaust.

 

Its close to 4k and i know 70 is almost exactly 4k rpm. So if n e 1 knows can i open the gear?

 

65mph for me is 3500 rpm.

 

same. the only way to "open your gear" would be to replace it or get a different final drive

 

that is normal, bu maybe old spark plugs are eating up a couple of miles per gallon.
