Best MPG?

[oandtmaster]

just drove to AC and back this weekend. 150 miles 22.8mpg

 

[CrackerJack]

I drove to the lake place we own, 24.3 MPG 93 Miles, about 80 of that I was doing at least 80 MPH

Driving to school all week I average 13 - 14...

 

[NYC LS8]

I showed 25.5 on a drive back from Georgia a couple of years ago. 80+ mph the majority of the 800 mile ride. That was with a KKM, exhaust and stock tune.

 

[Eric0508]

I average around 28 in the summer on the highway (60 mph) 26 freeway (75 mph) and around 17-18 city. In the winter its about 2mpg less all around.

I drove down a parking garage with the engine off, so about infinity i'd say.

i got 27mpg out of my v8 on the highway. intake only.

my old 94 camaro had CAI, pcmforless tune, long tube pacesetter headers, SLP loudmouth catback with moroso spiral flow where the SLP resonator was. that was about it performance wise....call it 325hp

30mpg all day long in 6th doing 70-75, boy do i miss that some days.

I get 25.5 highway, only thing done is a tune.

 

[hotrod03lincolnlsV8]

27.7 keeping it around 60. (Its not easy I know)

 

[WhoBeDaPlaya]

~25.5-26, running 80-90mph for 50miles. Stock '01 LS V8 sport.

I drove down a parking garage with the engine off, so about infinity i'd say.

my mpg went down a few tenths while leaving the parking garage at the casino. no throttle and min. braking... whoda thunk it?

The mpg calculator gets screwy if you idle for too long (eg. rush hour traffic, warm up in winter, etc.)

The faster you drive an LS the better the mileage

yeah, that seems odd. my 03 kia gets 30mpg at 75 and 35mpg at 55.

 

[scjmc]

My mixed driving was about 23.7 stock, and with Torries tune +intake it is 25MPG. Not bad for mixed driving. Highway is not much better though.

 

[601hotboy]

ive gotten an average between 25 and 28mpg on highway, i have gotten 30mpg to two trips. all completely stock.

 

[jason2000ls]

31.3 and have the picture. v power and octane boost highway. 20 ish in the city

 

[Stopsign002]

18 for a normal tank with 1/3 highway the rest city. Usually pull around 25 with CC on the highway doing 80

 

[ATrom]

Averaging 20.5 currently.Last week I drove just over 100 miles on the highway with the a/c on and got 29.9 with cruise set at 70

Nevermind the airbag light..taking care of it.. Stupid clockspring!

 

[Kumba]

Cruise at 80 I see about 25-26. Cruise at 70 I see 23-24.

 

[xford]

Best long term avg I ever had was a road trip from AZ to CA - avg 70-80 MPH and got 26.2 MPG with AC on most of the way.

 

[trickett90]

I get around 23 - 24 cruising just under 80 on the highway. Lots of hills here though.
