Totally agree with you, man. I've been around long enough to see people recommending all kinds of products with dubious claims that were never objectively verified or that, in some cases, were proven to be non-sense.

They happen on every forum. This one is, so far, very nice and civil. Some of the ones on NASIOC got outright nasty.

Agreed, most dudes have been nice. Only two dicks so far and one got banned.

Here we go someone said NASIOC. 2hat happened to those guys anyways.

That is interesting considering the "diesel like" sound you hear is coming from the injectors and high pressure fuel rail.

There are two kinds of snake oil. There was the 19th century folk remedy from actual Chinese water snakes where the chemistry made sense as pain relief. Then came the type that fools people.

I'm sticking with the idea that a known brand of oil that meets an engineering specification is exactly that and good.

This was long ago now, but in our fleet then we followed a few new semi tractors and light trucks life with oil analysis after break in. Synthetic type and not the brand is what was shown to be superior. Fleet was not my responsibility late in my career but the fleet people said that had not changed. They stood on getting the right spec at a good price was most important.

Guys, I am not bashing Amsoil products - they maybe a great products and alot of people swear by them. My concern is Amsoil will not state or guarantee their products meet or exceed the manufacturers specifications. If there is an oil related warrenty issue, using products that are not proven to meet the specifications would make it easy for Toyota to not accept the issue and void the warrenty claim.

I can't see Toyota taking it that far and opening up that can of worms; Amsoil isn't exactly a new, fly by night company.

Admittedly influenced by fleet and enterprise operations experience plus age I stick to a manufacturer's terms during warranty period and often beyond. Also get service performed at the dealers. It has never been any significant expense and has had times when I got coverage past warranty or the dealer on my side. The point of the fleet and work ops was that greater scale was showing more instances when it makes a difference.

So I'll throw my hat into this ring. I've been a long time Amsoil fan. Their fuel system cleaner (PI Fuel System Cleaner) has been amazing across both my Tacoma, and my previous Truck. While I've been trying to save money on oil this time around, since I'm changing every 3-5k on my truck, I flipped to using the Costo Kirkland brand. A week ago I've been intrigued with the Valvoline Clean and Protect oil. Research that if you wanna find out good things! I can tell you that my engine is actually silent now (just over 30K miles), so clearly -- to me this Valvoline oil is better than that Kirkland brand (no knock on it. It rates very well).

Furthermore I've drained both of my diffs same day I did the oil change and filled with Amsoil 75w-85 severe gear and man what a difference. The driveline is nearly silent, and zero lash or whip back at low speeds now. Just feels smoother. Damn if I'm not impressed.

Did the Transfer case tonight with Amsoil 75w-90 although I've not driven since refilling with that as of yet. Soon the Transmission is up, have 6 quarts of Amsoil ATF ready to go. Longtime proponent of their products.

0W 20 on the Restore and Protect? "Silent" is impressive.

I should point out that my Taco just rolled 30K miles, and It has become quite a bit more quiet staring around 24K miles. I barely hear the injector pulses anymore as I once did.

My understanding is that the Valvoline Restore and Protect is essentially a cleaning oil, almost like a regular oil combined with an engine flush.
