300 city or highway? damn, cause I prolly only get about 215 or more if city, or about 250 mixed, but if I do all highway then 300 or more is about right for me. 04 Lancer ES stock with MT. Or maybe its mostly how I drive, I don't usually keep it under 3500 rpm sometimes...haha

 

I fill up my car when the gas light comes on. That means I fill up with 10gal of fuel. 13.2gal tank I believe. In the city I usually hit about 320 miles.. and thats driving a little bit aggressive, but not too hard. (shift about 3500-4000 rpms) On the highway I get about 380 to 410 miles on 10gal. So thats about 32city/40highway. My engine mods are RRM Header, Injen SRI, RRM Test Pipe, Magnaflow Catback. As soon as I started modding my car I noticed better and better gas milage. I don't know why, cause some other people get worse gas milage. I think it depends on your climate and elevation where you live at though. I live 20-300ft above sea level in Michigan.

 

I have the RRM stage 2 turbo with 255 fuel pump and bigger injectors. I only get a little over 200 miles per full tank. On the highway I can get about 275 per tank. I don't think that's too bad for a turbo considering my fuel pump is like a damn fire hose! What sucks is that I have to use the highest octane gas! My wallet is hurting right now!

 

isnt this a repost!

 

that cannot be tue! there are new hybrids that dont even get that good of mileage. that cannot be possible for a lancer! are you sure your math is right?

 

i get about 230-250 in the city, and i dont know about highway dont travel on it too much.

 

on the highway the best i've done is around 360 when i was lightly modded...once i put in the headers + DP i developed a heavy foot again and only get around 230ish in the city and 270-285ish on the highway..

 

i've done 350 on the highway, but i don't let it get that low. i fill up around 300, just in case i miss the last gas station for the next 200 miles haha

but city, i dunno, less of course, i cant remember how much though

 

Positive its true. I'll take pictures when my tank gets around empty next round. I wouldn't lie about something stupid like this.. lol. I'd rather be getting worse gas milage because maybe then my car would be sucking more gas and going faster..

 

165 miles with the ses light, 220 without the ses light.

 

no pics man...i am in disbelief! I drive mostly (75%) highway and the best i get is around 280-300

 

that is with just an intake...you are more modded, does that play into your good gas mileage?

 

I was getting worse gas milage with stock header and a test pipe... then when I put on the RRM header, I got awesome gas milage. With stock header+test pipe, I was only getting like 24mpg city and 27 highway. Adding the header gave me like 180% better gas milage.. maybe it is just the combo of mods you are using. I still have the stock downpipe though. (manual trans..sorry I forgot to say that I think) synthetic oil too.. Mobil 1 5w-30. And a K&N Oil Filter.

 

wiretap you get really great gas mileage. I live in burbs of chicago, so it can't be that much different where your from. Everday driving for like going to and from work, school...mostly city, once in a while highway I average 280. Anything over that I get the gas light to come on. Now with my radar I have a heavy foot and gas light goes on around 250. I have about the same mods as you do besides headers, grounding kit, and spark plugs. Maybe if I get a header things will be better.

 

430miles on one fill up. I was running super lean and misfiring all the time :P
