On the way back from St Albert today I reset the fuel economy guage to see what I would get---drving totally on the highway.

Going 120km/h--75mph I got 7.2L per 100kms or 32.6 US MPG or 39.2 CDN MPG.

Not bad at that speed. Early on in the trip I was going about 60-65mph and it was down to:

6.4L per 100kms or 36.7 US MPG or 44.1 CDN MPG. Thats almost exactly what Transport Canada rates it at. No a/c--was not hot enough

Sure would like a nice deep 6th gear--about 3000rpm at 75mph.

 

At 75mph my auto 2.2 runs 36mpg at 2500rpms

 

How many Km are on your car??
I don't think I've dun that good yet but I barely hav 500km on my Balt

 

i drove to la from az and got 42 mpg at 70 mph

 

Noone likes you















lol, jk

 

Hey know whats crazy.... i have an SS and an SS/SC and the SC gets waaaaaaaaaaaaaaay better gas milage than the SS 2.4

 

werid. On the cruise up me and the other 2.4 were easily beating the 2.0 S/C cars---they were mad!

18,XXX kms on the car now---that about 11K miles

 

No whats crazy is that you have bothe.. LOL I had a hard enuff time convincing my wife to let me get one LOL

 

haha ya im super lucky

 

hmmm... i think that i do in the low 30s at 75 in mine, but bear in mind, it's summer in florida with super wet air... would prolly be better in a real state.

if i'm at like 45-50 i'll get damn near 40mpg, so i think a mid-high 30s 70-75 should well be doable. if i had to take a long trip i'd wax it fresh, and add 5psi to the tires... yeah, bet i could do it.

 

on a full tank of gas with Castrol Syntec and regular gas I would get 250miles per tank, now with Royal Purple and regular gas I get 320 miles per tank thats if I don't drive with the pedal to the metal lol. I would say I do 60% highway and 40% street driving.

 

7.5 I was not expecting that, my car has rarely seen the highway yet

 

wtf? how come im only getting around 29 mpg on the highway

 

Yeah at 70 I'm like at 31 or 32. I expected more; my old Beretta 3.1 automatic got better than that even at 300,000 miles on it.

 

i went from lakeland to panama city and back and the best i got was like 25.2 then again i was cruising at ninety to one hundred the entire way and hit this twice so i guess that isnt that bad....

 

hahahahah feel special I only get 25 maxxx..but I also have a four door

 

\

not much heavier then a coupe....

 

I usually get between 350-370 miles to a tank. I drive about 50/50 hwy&city and this is spirited driving. At 70 mph I am usually getting 34-35 and at 80 mph I get around 30-31. If I am driving mainly city it drops to around 27-28.

 

I haven't really had my 2.4 on the highway yet, I'll be going on a 200+ mile trip this weekend, we'll see how it goes.

 

holly my auto in canada i best i can get is 102Km/H witch gives me 32.6MPG

 

the best I have ever seen in mine is 24.9 mpg and it is currently at 17.6 mpg...yes my cobalt get worse gas mileage than the GTO

 

Damn, that's horrible. The lowest I ever got was about 25 mpg and that was basically flooring it everywhere I went.

 

Wow, That's F'd up man. I had a goat with an auto that got 15mpg.

My 2.4 auto gets 28-29 mpg commuting (1/2 city, 1/2 hwy) after my Wester's tune.

I think you should take it in to the dealer to get the A/F ratio checked.

Your MAF must be screwed or something. I think pig rich is probably an understatement - how about Hippo rich. How's your power? Maybe your cat is breaking down.

Sorry, man. Sounds like a warranty problem.

 

no I pretty much beat the ever living ***** out of my car. It also doesn't help that I never reset the DIC.....I achieved that 24.9 doing about 85mph - 105 mph for over 80 miles on the NJ turnpike. As for the cat, I don't have the notorious egg smell or anything of that sort, I just drive it hard....lol

When driven conservatively, we have gotten the GTO up to 28mpg, but normal "spirited" driving get about 19mpg - 22mpg

EDIT: Stop calling me man, man....lol I don't have that extra appendage ....haha

 

Pardon, mam.

You must really beat the crap out of it.

I hope you don't treat your men like that.

Though sometimes I like to be ridden hard and put up wet...but I digress...

Alas I'm married....
