You are correct that this is a Unicorn 6.0. Normally the 6.0's did not have AFM but because it's a hybrid it did get the AFM.

Having said that, I have a 2008 6.0 with 185,000 miles that does not burn oil but it's a cast iron block. You have a rare bird. What year is it and what is your city mpg?

2008 Tahoe Hybrid (PPV 3.08 Gear ratio) She gets 25MPG combined with the 11 year old battery

if it had a new battery it would be 31 to 34MPG combined. with the way I drive..

It was well taken care of Powertrain.... the old [censored] billionaire(the nooby billionaire) took very well care of it I mean they paid almost $70,000 for it. (right out)


the only thing that was not taken care of is the rear seats

(by the second owner) but I'm trying to rehabilitate them with heavy amounts of leather conditioner.... (they dried out) as they had car seat on them(so they did not get the care they needed)

i'm the 3rd owner so i have been keeping up on the maintenance and frequent oil changes 3,000 miles rule.. i might go to 3500 miles if it is still clean


the frequent oil changes = good for it
I'm quite surprised that it has no SLUDGE..


my old car had sludge but the transmission died at
189k due to a leak.. repaired at 129k so that is why I got another vehicle...(not economically viable to repair any more)




Also Legally it has 840,000 miles on it they screwed up on the title so i'm waiting on a replacement title with the corrected 84k miles
