Um, all of the 4.8, 5.3, 6.0, and 6.2’s too...;)
No consumption or sludge Here
unicorn.


Quick Question maybe your not consuming oil and just some phantom usage

how long do you wait or have the engine off before checking it? level ground too?

Without trying to hijack, has anyone tried a conversion from 5.3 to 8.1 on a half ton 2wd?

Welcome to the party! I have a 2003 Yukon XL 2500 8.1 that I use to pull a 26' 1948 Spartan Manor. I've traveled with it all over the west and for the past couple years I've been pulling it down south of Puerto Vallarta from Oregon in the fall and back again in the spring, about 5000 miles round trip. Performs amazingly well! Only issues I've had are with the transfer case encoder motor and dashboard cluster. Everything else is just maintenance and adding goodies. It gets between 8 and 9 mpg towing and about 12 otherwise. It uses a quart of oil in between changes. It has 160k miles and feels like it'll do at least that many again.

There are some good threads on here if you want to search for 8.1 or 8100. There's also a facebook group that Edward Cross runs with great info.

Enjoy!!

2004 Burb 8.1 with 260k and climbing; it's my daily driver. BlackBear tune really woke it up. 185 t stat helps with oil consumption. What questions do you have?

I'd be interested to hear your experiences with the tune and the thermostat, and how either one affected power, mpg, running and max temps, etc.
