OnTheReel Posted September 26, 2025 Posted September 26, 2025 The pendulum is starting to swing back from these low viscosity oils, I think. Maybe CAFE softening up a bit or the amount of warranty claims is becoming unsustainable. Early 5.0 Fords called for 5w20. They quietly bumped it to 5w30 for 2021. And if you add the factory supported Whipple supercharger? The spec becomes 5w50. Waiting to see if GM will follow suit. Even their non-defective “healthy” 6.2s have no business running 0w20. Not at the oil temperatures I saw on my stock 2019 and not at these OCIs either. In fact, studies have shown increased piston ring and bearing wear when the HTHS viscosity is at or below a typical hot SAE20. And the handful of 0w20s that actually are stout enough in HTHS are niche, expensive and carry no approvals. So for practical purposes they don’t exist. 1

OnTheReel Posted September 29, 2025 Posted September 29, 2025 It’s from Facebook so probably a big “if”…but “if” this guy is telling the truth about the oil change interval, that leaves the quality of the oil used, and the viscosity of said oil as two big question marks here. Even the non-wiped lobes on the cam look terrible. Not saying every truck is eating a cam at 67k miles but I’ve seen enough low mileage failure cases to be highly skeptical of generic 0w20 being run in any full size trucks. 1 2

This is what you were seeing in Your analysis when I saw it earlier. How’s the reports now?

Wear much improved! Nitration looks like Nicks! sux. A new engine well tuned should be much less than 11 abs units. If ring seal better it drops.

Boys we aren’t making meth or spraying nitrogen on fields. No engine oil has 10 abs units of nitration reading. You are nuts.

Grumpy Bear Posted October 1, 2025 Author Posted October 1, 2025 (edited) I've supplied numerous STLE and SAE articles and equipment vendors instructions on this topic. You can't wish a thing to be true. I'm not suppling more TRUTH from YOUR PEOPLE for you to ignore and confuse people with. Nitration levels are all over the map. 2 minutes googling others VOA samples. Background matters. It matters to the STLE and the SAE and to the people that make the instruments that measure it. You call me a liar and a fool and whatever else come to mind but it still won't make you right. Make you opposed to your own craft. Produce ONE single credible source that agrees with this fiction and I'll give it a second look. But until then...fiction it is. Edited October 1, 2025 by Grumpy Bear
