It’s true AMSOIL is outdated, but in a good way. Nowadays companies pitch a whole lot of fluff stating their products are the best and list a bunch of “scientific terminology” to persuade customers to buy into their cheaply made products. This is where AMSOIL is outdated because they take pride and truly stand behind their products like companies use to do in the good ole days, while still advancing their lubricants (oil, transmission fluid, coolant, brake fluid, etc.). They’re underrated because when it comes to the government setting the bar on classification labels AMSOIL says that’s not good enough and sets the bar even higher. Long story short, AMSOIL is the bar and no other mega company comes close.
More power, better gas mileage, smoother running engine it sounds like and feels like it doesn't have to work so hard to get the same power as before. I'm homeless so I idle my car a lot summer/winter since I idle much more than a taxi cab or police officer remember I live out of my car year round I might go with 5w40 next time instead of factory recommended 5w30 this oil ain't no joke!!! 2005 Toyota Solara V6 SLE

I did the first oil change in my buddies new Lexus at 500 miles for the break in service. I will update this review at 3,500 miles at the next oil change service.
Manufacturer calls for 0W-20. 5W-30 just feels better for my hot climate. My 6.2 purrs as quiet as a mouse (If you ignore the growl of the Flowmasters)
Bottom Line
Yes, I would recommend this to a friend.

AMSOIL Products

I continue to use AMSOIL products, because they are excellent. Also, they ship their items extremely fast. The quality of the products far outweigh the cost.
Well, oil is oil, so there is not much to say about the oil. Now the bottle is worth talking about. The wide mouth on it meant I didn't spill any oil while pouring it into the engine.
My order arrived very quickly, which is a plus these days. I have been having issues with parts arriving promptly.
