I noticed on my new 2002 2.5rs that I am blowing through gas pretty quick.

I have premium fuel in it and I have just recently used a engine cleaner on it so I dont think it is related to that.

What are some good methods to gain mpg besides driving like a old person .

 

First I'd go with Regular fuel, the biggest reason for higher octane is how it effects the flash point on the fuel, so unless you are adjusting the compression ratio's (like boosting) save your cash. I've got an the 06 and 05 owners manual recommends 89 oct, other then that I'm in te same boat you are.

 

Well I understand that, but in the end it only cost me like $1-2 more at the tank, so I dont really mind.

I was talking to cobb and they said cams, intake, ecu, plugs, and exhaust will do wonders.

 

hey cky47, how many miles are you getting in one tank. For me, in hawaii, i'm getting about 250 on the average. Mostly city than hwy.

 

I am about the same. I filled up last night withabout a quarter tank left and I had 205 milles on my trip meter.

 

ive been getting about 22mpg - 200 miles HWY -50 miles of mountain redlining

i drive 80 on the Highway, havent tried going 65 the whole time.
my miata would get 31 MPG going 65 and 21 MPG going 80!
