hey i own a 95 ls 2dr that only gets about 110-115 miles on a full tank of gas and its not like i actually put cheap gas i put the best that the gas station carry'z. And still same problem car has intake and headers and thats it no other mods, car has well over 200,000 miles but doesnt smoke or burn oil runs like a champ, only thing is gas milage is terrible any suggestion plz i would greatly be thankful. tia

 

wow.. thats bad.. fuel filter. spark plugs. 10w-30? does ur car run at a normal temperature? fuel injector cleaner.. also does ur car rev up past 1500-1600 rpms when u first turn it on from a cold start?

 

change primary o2 sensor
use short ram instead of cold air intake
check temp sensor

that's a start... usually, people get lower gas mileage during the winter... but 110-115 is crap... there's gotta be something else going on. GL

 

im getting about 150 per tank fill. but i also have a blown head gasket, piston rings are shot, and put crappy gas in it. (untill i finish my swap)

 

hey tell me about crap i changed plugs and i have fctry exhaust so i dunno i do drive fast on the weekends on the highway u no 100mph or so lol but ima change the fuel filter and im goint to get sum injector cleaner but not lucas ive heard and seen the bad things from that ish

 

on a cold start it goes 1400-1550rpms so im not to worried in that department lol
but i have noticed that when im driving mind u its very cold outside so im not sure about 13degrees i see a lot of smoke but seems to be from heat coming out the exhaust any advice
