Switched to Mobil 1 last weekend. Getting just under 16 MPG now, looks like I picked up about 1 MPG.

Update: I towed my 80, as well as everything I own, from Phoenix to Iowa last weekend. I'd guess I had 14K+ total weight, as both beds were completely loaded and I had a roof rack on the 80 loaded as well. The truck had a surprising amount of power- way more than any TBI or 5.7 Vortec I've driven.
I was able to maintain 65+ up 6% grades (and accelerate) if I was willing to let the 5.3 run at 4500 RPM+. My only gripe is the transmission, it wont let me give it more than half throttle without downshifting from 3rd (D) to 2nd. I never put the truck in OD. I think with a programmer to clean up the shifting the truck would have no problems whatsoever.
The mileage sucked, I got about 10.9 for the 1400 mile trip. Best tank was 11.5-ish, and worst was just over 10 MPG.
I took I17 to I40 to I35, avoiding most of the big grades. I pulled a few 6% ers but nothing like going through Colorado.
For pulling grades at altitude regularly I would want a diesel, but for occasional towing over non-mountain terrain, the 1/2 ton gasser is more than adequate, IMO. Night and day compared to earlier trucks. It pulled every bit as strong as the 150,000 mile 6.5 TD Crew cab I drove (and towed with) at my previous job.

I used to tow my K10 on my a car hauler behind my 01 GMC Sierra.
5.3 4L60E , It has 3.73's and It is Z71 . I hated it . I felt every bit of weight back there. Sold the trailer still have the truck looking to buy an F350 soon if not older Cummins like up to 01.
Oh here are specs on the K10
350/ SM465, Twinsticked 205
D60/14 Bolt 4 wheel disk
44" Boggers on 15" Steels.

Yeah man, I traded in my 06 GMC Sierra for a 07 Super Duty F250 and it is night and day difference. It tows and hauls a lot better, but it is a bigger truck.
