Gas Mileage Question

[LRegvall]

I know it's a little pedestrian for a performance oriented car, but I'd love to get feedback on what kind of gas mileage people are getting on their LGTs. I'm getting around 15 city and 22 hiway. I've never been 25% off of EPA numbers before and I've read published test reports ranging from 15 to 22 as actual tested mileage (which presumably is hard mileage). My tailpipes are also continually black indicating a rich fuel mixture. So I thought an unscientific survey would be interesting. Thanks.

City for me is 19 to 21 mpg normally with highway anywhere from 26 to 30 depending on what speed. I can get 30mpg pretty normally.

[rallispec]

i average 24mpg mix city and highway.

[waynekranzler]

I average 18-19mpg in city driving. On the interstate I'll get 27-28 at 70-75mph and 26-27 at 80 unless I'm driving into a major headwind.

OK, for you non-Canadians.. you wouldn't be impressed..

but for others I got about 400km on a half tank and readout was saying

6.6 to 6.8 l/100 achieved on my most recent highway trip.

 

that's over 42 miles per Imperial gallon !!

over 35 MPG (US gallon) !!

and it's a personal best for this car

 

13,500km on the car

i get an average of 21.9 mpg....thats mostly traffic jam/city driving

[t0ad]

So far I've gotten 21.4-22.8mpg with mine. That's 30 mile round trips to work via the highway .. I usually travel around 80% highway. Granted, here in WV you have to climb hills all the time, so no one gets good mileage.

Damn, I just put in my second tank of gas and so far I am getting 17.1 mpg, is the fuel effecincy low at first or am I screwed, cause I ain't even driving it nearly as hard as I intend to after I hit 1000 miles(250 right now).

[LRegvall]

I got around 16 city when I was breaking it in and started getting 15 after break in. Compared to the others so far here, mine is low and your 17 might also be low. You probably need a few tankfuls though to get the real trend. My dealer said they "checked it out" and that it was fine ("your mileage may differ"). I don't think so. My brother has a '06 LGT that gets right on EPA numbers and he doesn't get a black tailpipe.

[tigersan]

sounds like another reason for an AP(like I need any more reasons).

[chenc544]

'06 LGT 5MT with ~4000 miles and I average ~26MPG on 75% highway driving.

[TravisS]

I have black tailpipes, but so far I've been averaging right around 24-25 MPG with approx. 50 miles of highway / 10 city driving each day.

 

This thread might work better as a poll

Really people getting anything above 24mpg+ impress me. If I drive like granny I can barely make that... Like 75-80 mph.

 

Is my LGT a gas-hog or I am a lead-foot anyway?

[LRegvall]

I'm also curious as to whether anyone has had a fuel mileage issue solved, i.e, what the the problem might be.

[phoenix96]

I've averaged roughly 23mpg over the life of my car (just over 7000 miles), mostly city driving. On long highway trips I've gotten up to 28mpg.

[Fallschirmjaeger]

18,000 miles, 21.1 AvgMPG to date.

 

Like Pheonix I can get 28 on trips, but it drops after I get bored of driving 70 and decide to make up a little time.

 

Lowest MPG was 18.5 a week after purchase and I was still in the '"Grin and Go" mode from stoplights.

You might want to try a 'Search' also: I know this has been discussed many times before. I do recall there was one 2.5i owner that was trying to get his lousy mileage addressed under warranty - sounds like he had a real problem. I get 20-22 MPG on average, myself.

32hwy @ 75mph....

Overall avg 28:)

 

TDC for economy!!

hehe the more power you add the better fuel economy. Not many cars that run 12's (your going to run 12's with this setup right? ) hit over 30 mpg Amazing

[Vimy101]

According to the NAV/Info system readings if you're just tooling from light to light, you can easily "power coast" at 30mph in 4th. The instananeous mpg indicator buries itself and the throttle postion indicator barely blips. 40mph in 5th is no problem either. Now, you wouldn't want to accelerate hard with those low rpms but you can easily maintain speed or increase speed slowly. The boxer has a lot of torque. If I do let's say 30 mph in third, the engine is quite happy but the mpg goes down to less than 20.

 

I'm getting close to 25 mpg right now in 90F+ heat, very high humidity and the AC going all the time. I do a brisk freeway cruise and the Spec. sees numerous WOTs.

[RabidMonk]

I average 21.7mpg (22.8 according to the trip computer) on an 85/15 mix of city/hwy. If I am hard on the throttle on a given tank it drops to about 20. When gentle (rare) I can hit 23 and change.

[wukindada]

VT...I should be in the mid 12's.....with cooler temps hopefully in the 12.3 range, I'm really hoping to get a trap speed in the 116-120 range:)

 

If not......FP red is the next step;)

[VTGT]

hehe gotta love wagons. Now only if i could load up my tdc maps and i would be going in the right direction with mods

So just take a guess for me but how much did you invest in power mods to get to your power level. I am still split on selling my camaro and investing some into me leggy or keeping my cop magnet and leaving the scobby alone. I have more fun i guess building up cars engine and audio than keeping one for long. I have been in the domestic v-8 world for so long with this car that i am on a whole new learning kick. Any help you can give me would be great. If you wanna PM with some more info that would be cool. Thanks in advance.
