Dumb question, but I gotta ask...mpg and range
Has anyone gone over 600 miles on a tank of gas? I'm averaging 27-29 mpg on my commute and have gone 587 miles, but have not hit 600. You would have to average right around 30 miles per to hit that mark. It is possible, but you really would have to watch your driving to accomplish that.
I don't honestly notice a difference between mid grade fuel and premium, so I run mid grade all the time and it doesn't seem to effect mileage

More air = more fuel. I seriously doubt you will see any real improvement in your mileage with an intake and exhaust. They are not restrictive on the LS. If anything, tires with the least amount of rolling resistance and lowering the vechile to reduce drag would help a bit but the drag is already so low. Reducing weight also would help. I used to see as high as 33 mpg in my UL under ideal conditions but this was not sustainable due to the weather and the road. Just hypermile her by riding the *** of a semi...

Check tire pressure regularly as well.

Also was most of your driving highway by chance? I live in east bum **** ny small town usa thats super hilly so i would never be able to achieve that. I do agree about the tires though they play a huge factor as well.

Headers on the LS equaled about 15 HP from what I have seen. This is without a tune of course as I have never seen a tune for the LS. The reality is that people enjoy power and once you start trying to get more the right foot becomes heavier and mileage tends to go down significantly. Yes, when I got 33 is was when I was in GA on mostly flat highway use. I did not get this much once I moved to NJ. The intake on the LS is not restrictive. This is why no one makes an intake for it. Many people have tried and no one has shown any improvement over the factory that I have ever seen. Especially on a dyno.

My personal car is an 06 with an ls1 swap with a t56 its a completely different animal then the standered ls, i am looking for at a ats lsd and a custom ladder brace to reduce the body roll on this behemoth during cornering haha.
But anyways i am also wondering about the car ride height and chassis stiffness effecting gas mileage...sorry for thread jacking ime an a-hole.

Hey Lav. Good to see you in here. I bought an '04 last week. MPG display is showing 27-30. Haven't driven it far enough to actually check but looking forward to it. My '01 never showed numbers like that. Same general speed, same roads.

More power, more Air/Fuel meaning less MPG.
More MPG is more efficiency. Driving at the optemal rpm on the optemal day on the optemal road. Meaning using the least amount of fuel.
to make the LS more efficient you need max tq at carousing RPM. You achieve this by cam and tuning. But this will rube hp at higher RPM.

I have averaged as high as 27.8 mpg on my LS430 on long interstate trips using mostly cruise control. Have gone over 500 miles but typically refuel at or before that point. LS like most modern cars has fuel pump located in the gas tank and it is partially cooled by the actual gas. I am not sure but I think running the tank super low or dry could be hazardous to the fuel pump.

Have hit 25 mpg a couple of times on our '01 and went to 502 miles on a tank once but typically go no more than 450 or less before filling up.... At 27 mpg you are doing quite well but why try and go 600 on a tank? Anything over 400 is enough to go a lot of places.....

I have only tried to hyper-milage the LS once or twice, just to see if it's possible to hit 600 miles on a tank. I suppose if I was heading out on a cross-country journey I probably would see 600 and then some. I just don't know if my body (or my wife) could stay in the car that long nor is it good for the fuel pump to run the tank that far down.
For my commute I'm in the car for a little over an hour which is easy with this car! That Hyundai Veloster I had for a month and a half was murder on my back after about 35 minutes. Biggest reason I got rid of it...
