    Motor Oil

    The cheapest oil will probably be fine for short drain intervals, you’ll see benefits in more expensive oils when you run it for 10000 miles The psycological effect is worth something but that motor don’t care much since you’ll drop the oil again in 2500 miles. Non turbocharged engines more...

    2022 6.2 High Country - Low Oil, Likely Blown Motor

    That much going out the pipe figure you’d smell it see it or get a catalyst error 6.2 and 5.3 engines in the past did burn that much oil with pcv issues but that is all resolved by now by design change. assuming no leaks I would indeed question why the low oil sensor failed.

    Ceramic coat questions

    $1795 lot of money but it is on the low end for a pro ceramic coating for this size car. PPF and paint correction generally add few more bucks (why I’m not a big fan) to keep the coating in top shape you do not want to wipe down/touch the car much with anything, so wash with soap gun and Air...

    2023 Yukon Denali - Jack recommendation?

    Carefull with jacking up from the frame. I’s coated with some real slippery anti rust coating, car slipped off my jack in no time. wheels were on it so no problem. used the factory jack to lift it instead. Use jackstands or some other means of supporting the car. don’t rely on hydraulics...

    Chip shortage

    At this point in time “chip shortage” is induced by manufacturers of cars. Cars rely on chips made using mature—40-nanometer and older—manufacturing processes. Those processes make up most of the installed manufacturing capacity globally. If there was really a chip shortage Tesla would not be...

    The recommended GM Dextron ULV fluid is pretty cheap. people on youtube have used Amsoil and the Mobil 1 HP LV as well in 10L80 and 10L90

    2023 Z71 Tahoe Recall

    I’d almost expect these cars, especially the $$ Denalis/Escalades would have adaptive low beam lighting. I get flashed a lot at night. it’s probably the height difference. Europe light years ahead with approving/implementing this.

    10 speed trans question

    Waiting for an appointment (trans guy off sick) to check out the 10 speed shudder I’ve been seeing around 1200 RPM. I crawled under the car just now to check for anything obvious, did not see any kinked/ leaking lines but did notice few things, There’s two aluminum oil pipes coming out of the...

    10 Speed question

    Yes, Dealer looking at it Monday, plan is to swap fluid first. From looking under the Yukon easy DYI access for future, our 2016 MB GLE ATF fluid change is a royal pain in the butt to do compared to this one. (and the “gold” fluid is worth a fortune)

    What’s the Significance of a Build Date?

    Funny thing about build dates, most european countries when you sell a car you always list the build month on a car, like Mar/2022 or Dec2022 build date makes a difference when reselling over there big time. Jan vs Dec…

    10 Speed question

    I can reproduce the vibration in just about any gear now at around 1200RPM, very low throttle input, flat road, worst is at 43MPH exactly. Feel it in the seat / floor mainly. From reading my guess is the fluid change cure it. The fluid change seems real simple on this truck, pretty easy...

    What Oil To Use in My 6.0 Denali

    This is one of those threads that will give gravitational pull to just about any forum. oil when it’s on sale and do it yourself you can do a full synthetic change for about $40 including the filter on your truck. buy something that meets spec. just about any synthetic of the correct weight...

    10 Speed question

    Hi Guys, have a question is it 10 speed + lockup or 9 speed + lockup Last “gear” giving me a slight rumble around 40MPH , wonder if it’s the torgue converter stressing out due to it running at 1000RPM. anyone notice this ? in manual mode if I drop to 9 it’s gonzo but RPM’s don’t really change

    2.7 Turbo

    Back in 1993 a honda VX would get 57MPG on the highway. that was a stock production car. With all the hype and technology available you’d think we’d be able to squeeze more out of todays engines. even hybrid cars have trouble reaching that 1993 number, although the platform may lend itself to...
