    Lost the 6.2 (was: May have Lost the 6.2)

    Perhaps he was trying to "prove" that the 0W20 oil he loves so much can handle the abuse of such a situation (because you know GM had that use case in mind when they spec'd 0W20). Of course no oil can magically fix manufacturing defects or remove machining swarf left in the engine, but there is...

    Lost the 6.2 (was: May have Lost the 6.2)

    This has already been answered (a few times actually) and the answer is no. There is no proof because its just not true. Plenty of people have been using 0W20 with no issues for years, it is adequate in many (probably most) cases if no factory defects or abnormal use/abuse exists. 0W40 is...

    Lost the 6.2 (was: May have Lost the 6.2)

    Testing requires money, and the results of that testing would need to be financially beneficial to someone before they'd flip that bill. But there is, IMHO, enough field data to say pretty certainly that under ideal conditions (no manufacturing defects present or abnormal use) that an 0W20 is...

    Lost the 6.2 (was: May have Lost the 6.2)

    Wouldn't be the first time a vehicle manufacturer knew an life threating fault was present and chose not to do anything about because the cost of fixing the issue was more expensive than the lawsuits. Ford did exactly that with the Pinto back in the 70's, see link below to an article talking...

    Help, Need Guidance. 5.3L engine failure with no brakes

    You are "on here seeking guidance" well,,,,The issue is you don't understand how your vehicle works and as a result don't know how to drive it when all its systems aren't working perfectly. In plain English, the reason the vehicle didn't stop was you. Your "fear" and "lack of trust driving this...

    Help, Need Guidance. 5.3L engine failure with no brakes

    I get what you're saying, and that may very well be the way you remember it (panic and stress can cause some weird things to happen and result in your mind playing tricks on you). Unless the brake system was physically compromised in some way such that the fluid was gone, what you're saying is...

    Lost the 6.2 (was: May have Lost the 6.2)

    And you keep repeating what are blatant misinformed lies. Take the time to actually read what I wrote (assuming you understand the language). Physics does not change when boarders are crossed, 0W20 still NEVER outperforms or protects better than 0W40 oil in any situation, regardless of how the...

    Help, Need Guidance. 5.3L engine failure with no brakes

    With the power assist being gone, you just hit the hydraulic resistance of the master cylinder piston. Assuming the brake lines hadn't broken and all the fluid hadn't leaked out, the brakes would've worked if you'd have pressed them hard enough. The brakes requires a lot more pressure with the...

    Lost the 6.2 (was: May have Lost the 6.2)

    If the main bearing shells spun (which is typical) then the block is trashed too. Dealers here charge such a high labor rate, that its cheaper to replace an entire engine, than it is pay the labor needed to repair it. As for the 0W40 oil, no it will not fix bad machining or remove debris that...

    Lost the 6.2 (was: May have Lost the 6.2)

    Is it safe to assume that it was running 0W20 up until the test 38K miles? If so the bearings might have already been damaged during those initial 38K miles, but the PICO test should have detected that. Please keep us updated with what's going on as the saga unfolds. ...

    Help, Need Guidance. 5.3L engine failure with no brakes

    If the engine shuts off the power assist of the brakes and steering stop working, but both systems will still function,,, you've just gotta put A LOT more effort turning the steering wheel and pressing the brake pedal. Many people alive today (even some old people) have never driven a vehicle...

    Looking at buying a '22 - '24 Yukon Denali or Escalade L87 6.2

    The 6.2 recall issue is a problem for sure. But just playing the odds, its not a deal breaker yet IMHO. GM says the failure rate is 3%, but,,,they're probably low-balling the number some. Some of the pearl clutching click-baiters out there are saying the real number is closer to 6% (which is...

    I don't believe so, at least without lifting wires. I'm sure its technically possible to change the buttons operations via CAN programming, but its not a user option. ...

    What Oil for a 6.2 that passes the PICO test?

    Aren't those are just the different part numbers for various size containers the oil can be ordered in (i.e box of six quarts, 55 gallon drum, etc.)? Here are four of the part numbers (same two oils, just different quantity), there is a a fifth part in your pic, but its for a 5w50 variant of...

    What Oil for a 6.2 that passes the PICO test?

    There are actually two Mobil 1 oils , in 0W40, that are Dexos approved. The green labeled one on the right below is Dexos-2 approved and of course the Mobil 1 Supercar which is Dexos-R approved Screenshot below is from the Mobil 1 website, they even state that the supercar oil was...
