Last time I filled up, I only got 135. I did spark plugs a few months back, checked my tire pressure, also sea foamed my car a few months back. I'm about to change my fuel filter, since I haven't done that since I got the car(about 3 years now). Would that regulate my gas mileage more? Or what could be the cause that sometimes I get low mileage and sometimes a bit higher?

Also, a more important question, with my mods, is that just my average gas mileage now?

hmmm, something aint right. im getting better mileage then you and i drive my car hard.

next time fill your tank all the way up. drive around until it close to empty, fill up until the gas nozzle shuts off and divide that number(# of gallons) into how many miles you've driven. that should be more accurate then saying im getting 160 miles with it being between empty and 1/4 full or w/e
