LOL. No, I'm just reading too many articles on the dollar stretcher website. It's addicting, and makes you want to save money on everything in your life.
My Quest for Good Cheap Oil

Fortunately we have rigorous specs so we have more objective measures to compare the quality of oils. Supertech appears to meet API SP and Dexos 1 gen 3. Quaker State Euro on the other hand:
Enough evidence for me.
This winter it started at - 15° C without problems. 20w60 can do that, wow! Even if it gets late to get to the engine, that engine can take that punishment
I have QS synthetic in my garage, as well as Kirkland (same as Supertech). The Kirkland is a recent purchase. I'm more than happy to spend more on M1, QS, etc, synthetic, but until I can't find any evidence suggesting the Warren oils worse. Just opinions.
I'd love to learn more about Euro oil qualifications, showing they are more strenuous than API SP, but I've yet to see that. If anyone has info, please share. All I've seen up to this point, is opinion.
If he has the V6, I have that same engine. Maybe I should be the one preaching Supertech.This winter it started at - 15° C without problems. 20w60 can do that, wow! Even if it gets late to get to the engine, that engine can take that punishment
Yeah, V6, 3.4 I think.If he has the V6, I have that same engine. Maybe I should be the one preaching Supertech.
It costs money to test for different specs. Not all manufacturers want to invest the money. Particularly when it comes to Euro oils, because the number of BMW's, Mercedes, Porsche, and VW vehicles on the road doesn't make it worth the investment.
Ah ok so you hypothesize that the kind souls at Warren formulate Supertech to be robust enough to pass the rigorous tests for Euro specs out of the kindness of their hearts then without seeking the approvals?
Hopefully when I visit my dad when things get better, I will take three cases of Amsoil SS 5W-30 and nice oil and air filters for him. He won't have to worry for a few years. And some nice transmission and diff fluid too. I want to gift him an Eaton rear diff locker too but not sure if mechanics there can install that. Open diffs are not fun, he got stuck once.
First off, where is the evidence showing the Euro tests are more "rigorous" than API SP? I know they are different, but are they actually stricter? Is there evidence showing that Euro specs protect an engine better than SP, ILSAC: GF-6A? Or are the test just different?
I prefer the lowest cost option whenever I buy anything. All that money saved over the next decade will add up.

These house brand blenders buy pre-approved additive and base oil packages. There’s no cost for them to create and test creative blends. It’s bare bones and I highly doubt they pass more stringent approvals.
I searched on YouTube that are all oils equal. It turns out they are not. It's like getting all the ingredients and trying to make a cake, you cannot beat experience. You will make a horrible cake. I think we should trust Exxonmobil, Shell and Castrol for their cakes
I'm sure if you poke around enough here and there, you will be able to find answers to those questions.
True. In fact even within the Mobil 1 lineup you will find differences between oils with the same approvals. For example, M1 Truck and SUV is extremely shear resistant. M1 EP isn’t as shear resistant but is better for extended drains.

I spent a great deal of time in the BITOG UOA section, comparing wear levels of different brands and normalizing by miles driven in each sample. The end result is that all brands are within the statistical margin of error of the UOA tests.
As long as the oil meets a specification such as Dexos 1 Gen 3 for example, which sets stricter limits on sludge and varnish deposits than API SP, any other differences between brands are not statistically meaningful.
I prefer to do oil analysis the same way new medical treatments are evaluated and tested. Hunches and speculation are prohibited from medical testing. Only scientific evidence that a treatment works is allowed. We should apply the same standards to motor oil.
Assumptions like brand x is better than brand y, because brand x costs more than brand y is faulty reasoning.
Imagine if that faulty reasoning were applied to testing the effectiveness of different medicines.

Yeah, so true. Those two oils have identical approvals yet they are different. So what's the guarantee that Super Tech that has identical approvals is any good. That 400k Jeep on Super Tech says a lot about that Jeep, not Super Tech.
