My two cents is that you're not going to find an "expert" anywhere that can give you a conclusive yes or no answer for the Hemi 5.7L. A lot of folks "feel" like 5W-30 may protect better in the heat but FCA apparently didn't come to that conclusion during their testing of 5W-20. Apparently GM...

I don't know, if you really, really, really love your truck wouldn't every 2,500 miles or 3 months be even better for it?;)

Think you can hold out for a whole year?;) Yeah, the rear window frame is a bit worrisome, I can see the mold lines others have seen but so far no leaks and it's been out in some heavy rain. I replaced the halogen bulbs in the CHMSL and cargo lights with LED's and have worried about it leaking...

OLM down to 0% should've been a choice, which I guess is sort of covered by the <25%, which is what I do instead of picking a random number.

Agree that the one year maximum is what they could fall back on if someone neglected to change the oil for a long time, which does happen. The one year clock starts when you actually put the vehicle in service, not the build date, because it's not unusual for new vehicles to sit on a lot for...

Failed as in they didn’t perform well enough according to his tests to advance further in his competition to determine the best oil in the US. I can’t even say “his tests” with a straight face. Also, your experience with the Amazon Basics is not a bit surprising. It’s a very high quality oil...

I don’t think time really is much of an issue, oil doesn’t suddenly go bad after a year. My guess is it probably isn’t synthetic since Ram doesn’t require synthetic for the 5.7 it wouldn’t make economical sense to put it in as the factory fill, and most conventional oils anymore have at least a...

I’d like to see a couple of the oil companies that spent millions of dollars on research, development and legitimate testing in order to offer a quality product to their customers take legal action against him for earning an income by claiming their products “failed” his phony tests. But it’s...

Looking forward to a UOA with almost 5K on the factory fill.

That's the purpose of the Noack volatility test, which he tried to replicate. It estimates the amount of oil loss due to high heat in the engine. Some companies show the Noack percentage on their product data sheets and others don't. Valvoline just shows that theirs is <15% on most of their...

Oh yeah, no doubt! People just need to understand that he’s selling a product with his “tests” and he has to make them entertaining and lead people to believe he’s proving something. His cold flow tests are a great example. In this one he tests two synthetic oils of the same grade, they both...

The ASTM has several tests to determine the approximate pour point of an oil, D97, D5949 and a couple others. Pour point is the approximate lowest temperature that an oil is able to pour or flow out of a container, the idea being that if it won’t pour from a container it can’t be pumped by the...

Project Farms "tests" are entertaining, and make him a lot of money, but they really should be taken with a 10 pound grain of salt. His Noack volatility test is laughable. ASTM has had problems with repeatability for years with Noack testing, if anyone is interested in reading about it I've...

The folks in Japan have been working on 0W-12 and 0W-8 for the areas north of Alaska.

Here's an SAE chart posted at the PQIA website that the OP might find interesting. I've never noticed this before because I've had no interest in the 0W-16 oils since I have no vehicles that use it, but according to this there is a little overlap between the 16 and 20 grades. So, if a...

How's it asking for trouble if they've submitted the product for testing and it passed and is certified by the API and ILSAC and meets the manufacturers requirements? ST has passed the GM Dexos 1 Generation 2 testing which is an incredibly tough standard to meet.

I'd give you multiple likes if I could for being so right.

And I'd be willing to bet the rest of the truck will rust away long before the engine begins to wear out on that combo.

From what I've been able to learn from our mechanics the police Chargers are equipped with the severe duty II engine cooling system, which I believe is the same as what's in the SRT. I have not really researched this much, just going by what I've been told but it makes sense. But I think a...

Kind of long and rambling but he gives a credible response to the Uncle Tony video. Make of it what you will.
