Kirkland motor oil

I used it in my wife's Prius. Check back in 5,000 miles.

Ignorance is bliss (so they say at least) until you have a lubrication related failure. Then you'll change your tune.... as your wallet gets emptied.

Show me any documentation that the use of one oil over another, with regular oil and filter changes, caused any engine failures.

You're right, there aren't any.

Actually there are. In the early/mid eighties, Audi had 1,000's, of premature turbo failures on their I5 (2.1 liter) engines (which they fixed under warranty) due to oil coking up the turbo housing bushings because the turbo would overheat if it wasn't cooled down properly prior to engine shut down. (after spirited driving) It cost Audi $$$$$$. The fix: Change the specs to improve the temperature stability of the oil which led to Audi specifying synthetic oil and changing it more frequently. Also, install after run electric water pumps, water/oil cooled turbos, and after run radiator fans. To be fair, Audi warned owners about the cool down issues but hey, . . . . . who reads owners manuals? Some, not all, of the turbo failures led to premature catastrophic engine failures.

Other manufacturers had similar issues with their turbo models until the learning curve took over.

As I pointed out earlier, Kirkland's full synthetic oil is the same as Amazon Basic full synthetic. There have been several test done on Amazon's oil (been out longer than Costco's label) so you just need to look at those comparison test to see where it stands. As also mentioned, Project Farm's YouTube channel has at least two side by side test of Amazon's oil compared to other top premium oils. If you like what you see for Amazon's, you'll also like Kirkland's.

Look on your manufactuers website. Somewhere there is a list of approved oils. If Kirkland is on it you are golden.
I just bought the oil to do my annuel on my ISM and the generator. I am running Shell Rotella T-6. Dealer said he could get it for $35.00 a gal. I said I would bring him some I had from Walmart at $22.47. Keep in mind the ISM takes 10 gal+ then add for generator, it totaled at $339.78. That is just oil, no filters.

OK maybe we can get back to Kirkland synthetic now ;)

Exactly what specification does the Kirkland synthetic oil not meet for your 2020 F150?

If you read through the prior posts, you would see my comments were in reference to an oil marketed by a certain "national retailer", which was introduced into this thread by ItzyRV. It was not referencing Kirkland oil. That national retailer is Dollar General and is the defendant in the frivolous class action mentioned.

Oil that states this CLEARLY on the label.

So, it's all based on what can be tested now.

It still does not do away with the fact that it was a frivolous lawsuit as supposedly the oil in question was clearly marked with the grade and other language, like not made for most engines made after 1930 er duh.

The ambulance chasers mentioned fine print and being on the shelf beside oil that had a higher spec. Fine print my rear end. All legalized extortion and DG will settle as that will be the cheaper route, the class will get a Dollar General gift card worth $2.00, and the ambulance chasers will get millions.

It's not unlike the McDonald's coffee foolishness. Sure its hot, it's coffee. Just because your an idiot and spill it on your hoohaa, that should not give you the right to perform legalized extortion. I digress.

Well digressing as well, she lost the lawsuit in appeal, so McDonald's did not pay.
