I was wondering how many Miles per Tank yall are getting and what upgrades/mods do you have on your lade.

I am averaging around 260 miles per tank and looking for better gas mileage

My ext has a 31 gallon tank... I am getting close to 500 miles per tank... I am averaging about 16 MPG city/highway.

That's what I want to know as I barely average 15 in mixed driving(16 on long trips)
When i fill up sometimes the display show close to 500 miles till empty but i hardly get that

In the perfect world yeah, but is anyone else getting even close to that ? I should also add what size engine but i don't think it matters much

Esv's and Ext's have a larger tank than the base models so 4-500 mile mark per tank is plausible. I don't think anyone with a base model escalade that has a 26 gal tank is going to see that range.

I have the 31 gal but i forgot to consider the ext is probably lighter also maybe its a flat commute with no grades to achieve that, i don't recall ever seeing 4-500 range on a tank, even the bases should be close with a 5 gal variance

It depends on how you drive also but I have doubts about the ext being lighter as it is on the same frame as the esv

It doesn't seem like much but both side glass the longer roof and 3rd row accommodations (brackets and body strengthening) must account for something

Mr Holland nailed it... it is simple math. I am ,however, assuming that the trip computer is accurate and I am in fact averaging 16MPG. I have not filled up, reset trip meter, filled up again and manually calculated MPG... Last long trip I took, computer told me I was getting 18mpg.......

That's the way I do it when I get the average mpg
Last time I took a long road trip I got 16.7 mpg but I may see a improvement with new plugs in the engine

I've often seen no change or even a decrease in fuel mileage after a tune up, but an increase in performance. Probably due to the difference in the amount of fuel the engine is able to burn when its clean compared to being dirty. (Plugs, air filter and old wires with increased resistance)

-----Eh, what do I really know though.

I have seen a improvement in performance with the new plugs(I have a k&n air filter) but like I said I haven't made a long road trip yet to see if it will make a difference in the mpg for me yet

This makes sense when you make an equation out of it! Tune up = better performance = heavier foot = decreased MPG. Math doesn't lie, a tune up does decrease fuel efficiency.

2002 6.0L AWD EXT has k&n cai and corsa catback kit, im luck to see 350 to a tank! Ran sea foam in fuel system new plugs and wires.. Nothing has helped! I run 89oct all the time ive even put 91 in and all that got me was a lighter back pocket!
