Do you have any gauges on your car? If the warmer weather is helping your MPGs that much, the hot air might be leaning your car.

 

Are you guys who are claiming in the upper 20's for mileage, using the display or figuring by hand? My display will show in the upper 20's but that is not what I'm really getting.

It doesn's seem like its burning rich because the exhaust doesn't smell unusual and the inside of the factory tips were pretty clean. Since I put the Borla exhaust on, the inside of the tips has stayed spotless.

What type of gauges? Ya lost me lol

 

I figured by hand for that big trip. When I remember, I figure by hand but usually my homelink is usually correct

 

My homelink display has never been correct. The only thing I use the display for is the temp and compass.

I'm far too lazy and uninterested to home calculate. The idea that my mileage is actually worse then the computer sez is a little disturbing, but I still don't care

 

X2 I just put more gas in when it needs more.. I just check mpg on long trips ..

 

I figured mine with actual numbers. Looking around clubgp since you mentioned it- it seems that a lot of people with s/c GP's were able to pull 28-30 (saw claims from a few up to 35, but obviously no one has any way to prove any of it).

I definitely think 23 mpg with pure highway driving is definitely too low- but then again, it could depend on how you drive too- if its a hilly area, if you're going 60-70 compared to 70-80, etc- lots of traffic (having to adjsut speed a lot to compensate).

 

My 03's computer is way off for some reason. My 05 is almost dead on because I always compute my gas mileage by hand too.

 

My drive to work is almost completely flat. I drive around 70 most of the time except when I have to slow down for the two small towns I have to drive through and the last couple of miles to work. I just think that my car should be getting better than it does. My ex-wife and I owned a 98 GP GT with the NA 3800 and it got in the high 20's on the highway. I didn't think the supercharger would make that much of a difference.
