'05 Suburban 8.1L vs. 3/4 ton as dedicated TV
I have been searching for a used (~2003-2005) 3/4 ton truck to use as a dedicated TV but am considering going with a 2005 Suburban with the 8.1L with 130k miles on it. Specs on my TT are: Dry we...

"You may want to reconsider that 8.1. They have oiling problems. Do some research..."
Well, I had a Suburban 2500 with the 8.1L, and I did the "research," and the only thing I found was that the engine does "use" some oil. Doesn't leak any...just uses it.
This was the case with mine (a quart every oil change @ 5K miles) until I switched to synthetic....then no loss.
I work with a few ex-GM techs and they all told me that yes, it does use some, but it's just the nature of the beast. The start-up "piston slap" that so many bemoan is nothing to worry about....their words.
They also mentioned that there was a reason the engine was spec'd in so many industrial type applications .....they are super solid engines that have a very long lifespan.
I was very happy with mine. Still kick myself for selling it....sigh
