How in the heck do you pull 502 out of a full tank...

30 mpg.

it can be done considering the stock rating was 27 highway.

I have hit 500 on a full tank driving to florida on 91.

Here's a list I compiled. Depends on what year you're referring to.

97 SE 20 and 29, GT 19 and 30, GTP 18 and 28
98 SE 20 and 29, GT 19 and 30, GTP 18 and 28
99 SE 20 and 29, GT 19 and 30, GTP 18 and 28
00 SE 20 and 30, GT 20 and 29, GTP 18 and 28
01 SE 20 and 29, GT 20 and 30, GTP 18 and 28
02 SE 20 and 29, GT 19 and 29, GTP 18 and 28
03 base 20 and 29, GT 19 and 29, GTP 18 and 28
04 GT1 20 and 30, GT2 20 and 30, GTP 18 and 28
05 base 20 and 30, GT 20 and 30, GTP 18 and 27, GXP 18 and 27
06 base 20 and 30, GT 19 and 28, GXP 18 and 27
07 base 20 and 30, GT 19 and 28, GXP 18 and 27
08 base 18 and 28, GXP 16 and 25

08 must of had some strong emission changes.

No, they've revised it to be more "accurate".

Yet now i see the focus claiming 59 MPG when ONLY the hybrid gets that.... and thats highway.

And no, you can't buy the hybrid in canada yet.

closest you can get is the titanium which is 45 mpg highway.

i do a LOT of highway driving. at 70 mph i get about 23mpg, at 80 i get 20ish actual. According to the DIC I get 26@70 and 21@80 It also says I use 40 liters of fuel (yes im canadian and dont want to convert liters to gallons) when I actually use 46 litres. I've never had it even close to accurate to being how much I've used. Does anyone else have that problem or are you getting a fairly acturate number on your fuel used?

My Regal used to be dead on. After I got a custom tune though, the actual has been about 2 mpg less than what the DIC says.

I can't keep my damn foot off the gas, but I did get 27+ going from n. cali to s. cali mostly doing between 75 and 95mph the whole way, normally getting a combined 23 mpg or so. i know i could stretch it big time if i didn't have a lead foot.

I can never get more than 22 mph average. Weather or not I do a lot of highway driving.

428km trip, 24.14 mpg according to my iphone app. Mostly highway driving but a bunch was on windy mountain-ish roads. Long 3-4k pulls up steep hills. Not bad considering I just bought the car and haven't done anything but put a little bottle of Lucas in my gas tank. I bet I can get it to do better.


3.1 motor with 243k kilometers (151k miles) on it.

So what would cause my DIC to be so far off from actual then?

I get about 330ish to a tank. I average 24.9 driving with my foot more into the accelerator. If I drive respectfully, I can get 29's to the gallon. My regal has a smaller tank I think than thr GP's and def only gets 93 octane. Wish I could find 94 octane here in Cincy.

I get like 16mpg city...I would be upset, but driving a V8 is kinda worth it

23.5 city like clockwork, my 97 DIC is also dead on most all of the time..... 28-29 highway according to DIC only.

my 97 gtp gets 26 highway

715kms, 25 - 26 Highway

2000 GP GT

i get like 200 miles on a full tank lol if im lucky.
