      6.2 owner ready to jump ship to 6.6 gasser

      By kevin74 · Posted

      I normally use a mix of 87 and 92, depending on which I feel like buying at the time. I haven't really seen a difference between the 2. I am not sure what the ethanol content is as I usually only worry about that with the lawn mower and atv's. My "normal" gas mileage is around 14 with stop and go traffic, I can get into the 20's (22 showing as best) when on longer highway and interstate trips. I don't get on the gas leaving stop signs or red lights, and I don't idle a lot.

      Engine Failure - only 76,000 miles

      By Grumpy Bear · Posted

      Yes   Several parts of the motor are protected with such screens. VLOM, Oil pump, VVT solenoids, vacuum pump.    The intention is to catch debris that would damage or interfere with that parts job.    Problem is that they also are a collection point for varnish which is not a solid but 'plates out' over hundreds of heat/cool cycles from oils either not polar enough to hold them in solution or in oils run so long they fall out of solution. That is reach their saturation point. Either way, the screen plugs over time and whatever is downstream starves.

      Another 6.2L engine failure!

      By el ess1 · Posted

      When I bought my 2020 Denali 6.2 new (built in late November 2019), I was pretty happy to get all the discounts piled on and employee discount at the time, and all that since the Covid bug was killing sales. Saved a ton of $$ on it. When signing the paperwork, I bought a no time limit, 150,000 mile drivetrain and major systems warranty through the dealership with a $100 deductible per incident because of the then-new to me cylinder deactivation. Wasn't going to at first, but those deactivation destruction stories from years past kinda scared me a little, enough to say yes. The only thing in it that if I have warranty work done, it needs to be done by the dealership or an ASE certified mechanic or shop. Warranty work done at Joe's Machine Shop with Johnny Shadetree as a mechanic won't fly. By the way, buying a new vehicle during the Covid outbreak was a weird experience.   The same dealer services the truck when needed so it's well maintained, even though it only has 8,800 miles on it after 5 years of ownership this month. Since the 2020 L87 has no way of cleaning the backside of the valves of oil buildup, I put a catch can on the PCV system to help cut down oil ingestion) Shortly after purchase, I thought the almost $2K I spent for that warranty was a bad idea because I normally have had good luck with GM trucks, but figured that was a sunk cost and bit the bullet. Now I feel a bit more relieved by having it with this 6.2L thing going on. At least there's a 50/50 chance a new engine may only cost me $100 if the worst happens. What I'm not understanding is if they've had the same issue with the 2019-24 6.2, why did they cut off the range of "recall" coverage? Or was that the NHSTA's assessment to include 19 and 20 models as problem children and GM decided the range?    Crossing fingers, I'm very happy so far that the only issues I've ever had with the truck was the infamous rear window water leak, and a BCM went bad (truck sat at dealership for 3 weeks due to national backorder on those), both issues fixed under factory warranty, and I replaced the original battery in mid-April '25 as it was starting to get sluggish when starting. And most recently a bad fuel pump driver module I replaced myself a week ago. I'm hesitant to put in 0W-40 oil in my truck because if I ever did have a problem, pretty sure my truck's aftermarket warranty won't cover it for not using the "correct" oil, but yet, it kinda worries me a bit of having to leave 0W-20 in it. Guess I'll just roll with it.

      Definitely one would have to do a lot of accurate mileage testing to crack that nut for sure, based on the 3% difference in energy it would equate to around a half a mile to the gallon for example with a truck like mine.
