    Dexos D list update!

    Screw it, I'm doing a C3 5w-30. Dexos D licensing is a s--tshow. I'll take my chances.

    Air Suspension v. Longer Wheelbase

    Wheel diameter and tire sidewall profile have an impact on ride quality, as well.

    Does Your 21+ SUV Hold Any Sentimental Value... What's Your Story?

    Waterless wash is really a time saver versus the old way of doing it.

    Does Your 21+ SUV Hold Any Sentimental Value... What's Your Story?

    I had a nonturbo 1980 4 speed GL Subbie wagon I bought new. I had to row the 4 speed between 2nd and 3rd to get it uphill in CO. Cool car otherwise, but the engine was totally underpowered. As far as the Tahoe goes, it's love and hate, love to drive it, hate to wash it; so huuuge! The 2025...

    Test Drove a 26 HC

    Those are the 100 lb wheels and tires. They look awesome, however. The ride is not bad with air suspension.

    Test Drove a 26 HC

    Its probably the Ram charger in his signature. I used to use a brown one on an oil project.

    Test Drove a 26 HC

    Very nice Yukon! FYI, each of those wheels and tire combos weigh 100 pounds. Love the 24" wheels with the air ride but they are heavy to rotate yourself. Make sure you get the wheel lock key; it is different. I bought an extra, just in case; $38.00 plus tax and shipping.

    [SOLVED] Latest OTA update stuck at 68%

    My USB sourced music now repeats an album instead of finishing it once and going to random since 654.60. :dunno

    What’s the consensus on the Duramax reliability?

    '25 Tahoe HC, 9,800 miles now, still 24 OA mpg, love my LZ0, May build.

    Do I wait for the 2027 MY to come out? Buy new now?

    While I would wait, I did buy a 1999 Silverado; 1st year of the new style. I could have bought a new truck with the out of warranty repair costs, however, the 5.3 non-afm and 4 speed trans were solid for 150,000 miles. Costs were mainly suspension and electrical. With newer models being...

    Code P06DD thrust bearing issue...

    Highest LZ0 thrust bearing failure percentage I have seen on the interwebs is about 2.5%. Seems to be a bit of an over reaction to me. I'll take my chances, given I have a power train warranty.

    Fuel Economy Tanked

    '25 HC with 24" factory wheels, LZ0, 9,300 miles now with about 2/3rds highway, no towing, lots of luggage, cargo from cleaning out deceased parents house; lots of highway from that. 24 MPG per the vehicle computer OA. I'm completely satisfied with the mileage, especially in comparison to a...

    GM must be doing well

    Had one in a 1999 new style Silverado. Engine was awesome, 153,000 miles from me, sold it to a neighbor kid and is still going strong at over 200,000 last we talked, rest of the truck demonstrated why you shouldn't buy a first year model if you value reliability. I could have paid cash for a...

    Asking for pricing advice 2025 Tahoe

    I got $4,000 off sticker on a 2025 HC diesel optioned Dark Essentials (24" black wheels) and HC Deluxe, with 9 miles in May of last year. Geography may play a part, demand in different areas of the country and all that. No upcharges either. You might do better if you are not in a high demand...

    [SOLVED] 2026 Tahoe Z71 Duramax Oil Change with Skid Plate

    FYI, the oil really comes out fast from the pan if you fully remove the drain plug. As you probably know, diesel oil stains whatever it lands on more persistently than gasoline engine oil, if that matters. Don't ask me how I know. :confused:

    GM must be doing well

    Last I heard, Escalades are leaving Arlington in MY 2027, Cadillac electrification; maybe, maybe not with the last federal election. That departure will make more capacity available for Tahoes and Yukons. So, demand for full sized GM SUVs is quite high, hence the allocation situation as it...
