01 yukon stock wheels and tires....I'm getting around 20 on the highway at about 60-65mph...city mpg is uncertain as I don't pay enough attention to it. but I would say in the 14-15 range.

Seriously??? What are you doing to get 20 mpg on the highway? I get around 16.5 and I try to take it easy...

 

[TWITCH101]

Honestly I have no clue and I thought it would bring some attention since everyone was getting around the 16-18 range.... I was getting around 17-18 when i bought the thing and replaced my spark plugs and coil pack wires with iridium plugs and just regular wires from advanced auto parts and I think it gave that little bit of extra bump to get my mpg up.....but since we are on the subject if someone would let me know what size gas tank i have I could recalculate my mileage and make sure its accurate...I've been calculating mine with a 23 gallon tank so if its too much larger than that then my numbers are off.
Oh and I drive like a granny when accelerating to the speed limit.

I have an 01 yuk and my tank is a 26 gl. As for my mpg, I will let you know after my next tank. I'm on my first tank with my new 22's and right now I'm hoping this will not be the norm. I've driven 193 miles and I have a 1/4 of a tank left. Normally at 1/4 of a tank i've gone 250-275. I filled up two friday's ago and put 22.71 gallons in. If I get 225mi out of this tank that wld be 9.9 mpg, 250mi that wld be 11 mpg. Before the 22's i was getting 13-14 city. So again, I will check with my next tank. Getting a BB tune next month, don't know if Justin can tune it to help accomodate for the 22's but I hope so. I should add that I need to get an alignment real bad and that will be next week, this has a slight negative impact on mpgs so not panicing yet.

Its a very good possibility that I could be wrong on the amount that the tank will hold but I know for a fact I can go 200 miles starting with a full tank and have more than half a tank leftover and thats with about 2 hours at 55-60mph and the rest of the drive on the interstate doing 70-75mph.
I'll see if I can get a more accurate reading the next time I go home for a weekend.

[01HDtahoeNJN]

Dont really know with out being able to look at it first hand.

When was the last time it had a tune-up? Filter clogged up? Brakes dragging? Bad U-joint in the driveshaft?

 

[01HDtahoeNJN]

Not quite sure but its probably had one before I hit 100,000..I got it at 91,00p

Bro, 245 sounds low, on my stock wheels i would go 290-315 on a tank. Take it to a local shop other than the dealership and have them look it over.

size of tank should make no difference when calculating MPG anyway because it's miles driven divided by gallons used. The gallons to fill up the tank don't factor into that calculation

my 2004 Yukon only has 18k miles, stock everything, nothing done to it at all...i took her on a road trip this last weekend and got 18 mi/gal.

 

[Twinrotor]

Combined mine stays right at 15 mpg, that is a range on 390 miles. When we took a road trip two weekends ago, it ended up going 430 miles on one tank, and I only put a little over 24.5 gallons to fill it back up thats an average of 17.4XXXX mpg.
