2026 Tahoe with 6.2, im all good?

[ReaperHWK]

Solid!

Keep in mind though with the 6.2 I’m using 93 octane so kinda offsets a little with the per mile fuel costs since your paying more than 87.

Yeah exactly. Premium only tends to be 10 cents more per litre where I am…. Like 37-38 cents per gallon. Not a huge hit at these prices but not nothing.

 

[Stbentoak]

Premium is a solid dollar more a gallon most anywhere in the states where we are. Costco usually does a little better It is about 60 to 70 cents higher than regular. No matter what premium is the biggest rip off out there. You have to have it, but it used to be 30 cents more a gallon... now a dollar.... Pretty much common.

Looks like my truck averaged about 15mpg over the 5000 miles since new. On the highway it gets mid-low 20’s.

As much as the fancy displays and computers seem great, you should log fuel and perform manual calculations for comparison. You will find the vehicle calculations vary. City is usually lower and highway (<66mph) could be higher. I have been logging fuel for the last 8 years on 5 different suvs and all are a bit off.

Yeah it’s pretty crazy what some of the spreads are. Complete rip off lol.

One thing I’ve noticed with my ‘24 Yukon XL diesel is the computer read out is insanely accurate. Often bang on or only off by ~1-2% max.

I get that with diesel rides, but I have not made that change over yet.

My computer is usually off no more than 0.1MPG vs manual calculations. But, that is only true if I fill up at the same station using the same pump. If you park on a slight incline vs a decline, or fill at a different pump, you can possibly add or not add a half gallon vs prior fill up. This is enough to make one think the computer is “inaccurate.”

I don’t think one should put all their faith in a pump reading either. I know there are checks and balances but the financial incentive to cheat is a variable that can’t be ignored. One day I will do a manual calculation of my gas mileage for SAG since I do use the same station most times I buy gas unless I’m on a road trip.

Well back to the topic at hand just changed the oil today at 6100 miles. Also before I changed I checked the oil level and there was still ZERO oil consumption. Put in 8 qts and it registered right in the center of the hash marks on the dipstick. Also prefilled the filter with half a quart and oil pressure shot up almost instantly. Would highly recommend doing this especially since the filter is installed vertically and easy to do.

Will change at around 12000 miles and send in for oil analysis. Figure 6000 miles on the oil will be good for the analysis. Will post results.

I used penzoil ultra platinum 0w-20. Oil filter is a carquest premium(advance auto). Also running a catch can and AFM disabler (range) to be transparent since day 1.

Also this is the 2nd oil change. The original oil was changed at 1000 miles by the dealer with whatever crap they used and I changed today at 6100 miles with the premium top shelf oil.

So not to beat a dead horse..... so does anyone know what the actual failure rate is on the 6.2L? Was looking at a FB page with many folks claiming they are on their 3rd or 4th engines and engines are on a 9-12 week backorder. You'd think the roads would be littered with failed vehicles. I've not seen a lot of chatter here in recent months which leads me to believe that those that are going to fail have already done so.

 

[GMCnewbee]

That horse is buried. But to your point, what I have seen here on the Forum is that the "official" numbers from GM for 6.2 engine failure are something like 3% to 5%. When you are talking about 600,000 vehicles that is 18,000 engines, which is A LOT. More importantly is if it has happened to you it could be or it has been a disaster! For me that is that value of this Forum, to hear from those who have had to deal with this, and to be prepared for it or to take action to avoid it. I just did a 500 mile trip to Miami and back, tried to stay in the right lane, keep it around 70, and pay close attention to how the engine was sounding. Everything was OK except for the Fuel Pump Module that failed while we were in Miami. We have a 2022 Denali with 27k miles so far. I will be trading it when the new motors come out and have proven "OK".

As I posted previously on the latest GM earnings report, they beat estimates for revenue and margin with positive guidance.
No mention of warranty issues affecting margin or revenue. That doesn’t give us an exact number but the data indicates
it is not significant.
If the failure rate was even 5% of one the biggest revenue streams it would have to make the earnings report.
Financial reports are subject to scrutiny and SEC rules and if GM was fudging anything that would be sanctioned and big news.
As always if you want truth - follow the money!

This doesn’t help anyone in that 3-5% but perspective is important and any mass production that has a 95%+ success rate is pretty good.

The recalls did appear in the 2025 earnings report, and they contributed to a 35% decline in net income in Q2 2025.

"RISKS
Warranty Costs: Paul Jacobson said, "for the full year, we now expect warranty to be a year-over-year headwind," citing higher claims for both L87 powertrain and early EV software issues in 2025."

35% decline in net income?
That is way more than significant which contradicts guidance from the earnings report.
I looked at the report the day it came out and GM was definitely up on guidance at that time.
I have to check this as it is 180 degrees opposite to the guidance I saw a couple weeks ago.

 

[BacDoc]

Not sure where you got that information but the most recent guidance was raised and the margin is significantly better according to guidance.

The only downside I could find in recent AI search was this:

It says “raising guidance”The only mention of “headwind” is the EV segment.

If warranty claims are 35% that would cut margins significantly don’t you think?

 

[BacDoc]

I don’t hold GM stock and don’t plan to.
Just pointing out how well they performed financially over the year and especially the latest earnings.
This is a snapshot of the company as an investment in the sector and I didn’t see any mention of warranty claims affecting revenue or future earnings.

Mine was from the Q2 earning call in 2025. Remember, the recalls don't go through 2026 vehicles, yet...
