So far I've been generally happy with my 2020 5.3 Elevation, but as of late it's been burning oil. 3 oil changes ago, 2 qts low, perform GMs consumption test, no loss, next oil change 2 qts low. I'm still under extended warranty for 14k ish miles, but am wary of trusting it, despite reading how common it is. I would like to keep the truck forever, and if adding a qt of oil will let me keep it theoretically another 5 years, I would, but am not sure that's reality here? With all of that said, the tech kept referencing how ~1/3 of my engine hours are idle hours. I live where there's a ton of traffic and it's pretty cold, so...I either idle in traffic or idle picking my kids up/dropping them off at school, etc. 58k miles on it, mostly city.
Is the idling thing BS, or accurate as it seems from reading? Can I save/protect it by 3-4k oil changes and keeping it topped off, or should I trade it in now?
For clarity, looking at a 3.0, but I don't tow or anything so it would be for MPG only, OR, a 2025 SR5 Tundra. At any other point in my life I'd be like, Hell Yeah, new truck, but I'm at that stage where ever penny goes to my kids, so if I can safely avoid a new one and get another 50-75k miles out of this one, I'd like to.
Would love some thoughts, if anyone has any to share! Thanks!
