Ok so i have an M6 with 3.42 gears were should i shift to get the most out of my gas tank??? I was shifting at 2k today and it seemed like i burned alot of gas faster than usual??? I do a combo of city and freeway driving so let me know ![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)

I think you could shift as low as 1500. Just get up to speed as slow as possible and shift early and you will save gas that way...yea it sucks but that is basically how you do it.
I was driving my buddies grand prix and he was like, "jeez i've never gotten mileage this good before"

to keep mileage up, 1-3-5 shifting is good, most in city cruising speeds can be maintained in 5th, 6th may be usable for some situations as well.
Avoid blipping the throttle and varying speeds, if you drive at constant speeds, the mileage stays up. quick starts off the line eat up the most gas and WOT runs. For daily driving I find there's no need to use more than half throttle, heck I think I get away with 1/3 throttle most of the time and 1/8 throttle to maintain speed.

Awesome sig pic, I've seen/read about those chase vehicles, but that pic is awesome.
Oh and yeah, give as little throttle as possible, skip as many gears as possible, and shift as low rpm as possible. Though that all takes more self control than I usually have, but hey I still usually get over 21 and that's with top down and/or ac on so really not that bad. I've gotten up to 24mpg when trying hard to see how good I could get. BTW this is mostly highway...city driving/lower gear drivving will knock your mpg down. BTW, I've driven mine as low as 800rpm in 6th on moderately hilly back roads quite easily, don't be afraid to run really low revs, no problem for such a monster torque motor like these with such a relatively light vehicle.

LS1's are gas hogs! But I just got my tune smoothed out and my MPG seemed to be pretty good this past tank with my hard street tune miles and my WOT runs to make sure the tune was on.

I have a 2000 WS6 M6 and I shift at 2000 rpm, don't skip gears and leave it in gear during decel until the rpm hits 1000 then I push the clutch in. Last tank I averaged 24.2 city/hwy with about 70 percent of it being hwy. I went 335 miles before I filled up.
I am going to try the 1-3-5 skip next tank and see what happens! But, I think it will take the fun out of driving a manual.

I seem to get decent mileage even though my tune is way off. It is running super rich. I think going into neutral every time I come to a stop helps quite a bit. The first tank I went through I didn't do it and my mileage sucked. Now that I'm tired of the 50lb clutch pedal I go straight to neutral whenever I can.

bone stock lt1 M6 = 27 hwy (consistently) 18 city (consistently)
not skipping gears, just accelerating easy (no rush) and shiting at about 2k.

when stock, 19mpg city was normal with 22mpg avg with a 50/50 mix of driving. 28-30mpg was on tap for 90% highway.
Now I'm lucky to hit 25mpg with 100% highway. 16mpg city and 18-19mpg avg.
This is what modding does to mileage. That and a careless right foot. Pay to play is my motto.

The biggest factor is the driving style.
Don't pass people.
Don't drive over the speed limit. I can get 33 MPG at 40 MPH lugging it. Sixth gear. But I only get 27 MPG going 70. Going 80? I get about 24 MPG.
Drive with the minimal RPM you can get away with.
Skip gears.
Shift to N when decelerating if your car doesn't hit DFCO.
Don't pass people or accelerate unless you absolutely have to.
Then, the route you choose.
Obviously, not getting into idling situations is nice. Choose streets with lower speed limits.
Then, the idle time.
Cut the motor when you have to stay stationary more than a minute.
It will make up to a 25% difference in fuel milage. Remember, changing your speed (accelerating) and the resistance of air are your enemies!! Even if you are gradually picking up speed you are using a hell of a lot more fuel than if you were simply maintaining your speed.
