    2017 Escalade/Denali L86 "requires" 93 octane - your experience?

    The 2017 Denali and Escalade Owners Manuals say "Fuel (L86 6.2L V8 Engine). Use premium 93 octane unleaded gasoline in your vehicle. Unleaded gasoline with an octane rating as low as 87 may be used, but it will reduce performance and fuel economy." I know that the engine computer can enrichen...

    2017 Escalade versus 2016 Tahoe for Towing

    My 2016 Tahoe LT has the NHT Max Towing Package and 135K miles with a GM re-manufactured 6L80E a year ago at 125K miles. Two years and 90,000 miles to go on the factory warranty. In south Texas, snow is not an issue. I like that it is 2WD with the locking differential instead of 4WD. I put...

    I have a 2016 Tahoe with the "NHT" Max Trailering Package with a sick transmission. I'm looking at replacement with a reman transmission.

    Help 2007 Yukon XL Denali 6.2 L Dies at idle

    Per the subject line, my brother has a 2007 Yukon XL Denali with the L92 6.2 liter engine. I have looked through recent posts and did not find a situation like his problem. Randomly, it will die as he comes to a stop with a warmed up engine. There is not a problem with starting, so it doesn't...

    Need a backup bells and whistles key fob

    My Tahoe came with only one of these. They didn't tell me until after all of the pre-purchase stuff, which only needed one, was over and they said here's the key to your Tahoe. Huh? Only one? So I didn't have any leverage on them. Oh well. On eBay I see these for anything from $20 to...

    2016 Tahoe 9C1 questions

    Hi. First post. I drove a 1995 Caprice 9C1 for nine years and 100K miles and liked the performance and heavy duty construction. Now I'm looking at a 2016 Tahoe 9C1 to tow a travel trailer. It has the 9C1 code on the glove box Service Parts Identification (SPID) listing. The SPID has the...
