In addition to having the Oil Filter to allow me to go 12,000 miles between oil changes, the AmsOil XL Boosted motor oil is so much better than OEM oil which came in my 2016 GMC Yukon Denali. Thetruck funs smooth as silk and I think its getting better MPG!! Nice!
Always a remarkable change in sound when changing typical oil to Amsoil. We have gone to Amsoil for all our vehicles. This 0W-20, is used for our Suburban. Wouldn't choose anything else. Record your vehicle's sound before changing. Then play it after you've added Amsoil. You'll be amazed.
I send all my oil in my Infiniti G37 Sedan for lab testing, and Amsoil has surprised me and outperformed Mobil 1, Castrol, Motul, Liqui Molly, and Royal Purple. Least wear of any other oil I have tried — especially iron.
As a courier driver I drive over 500 miles a night M-F. My car currently has a bit over 370,500 miles and last year I put 130k miles on my car. I use Amsoil XT because I believe it offers the best protection for my engine and with 12,000 mile intervals it is very economical. Even at 12,000 miles, the engine oil looks far cleaner than conventional oils at 3,000 miles or other synthetics at 5,000 miles. Only oil I'll use.
Best oil ever. Using it from day one on my '09 HD, and my 2013 Highlander and 2018 Tacoma V6. My truck gained 2mpg when I began using in 2019.
Yes, I would recommend this to a friend.

Amsoil products are terrific. I've been using them for over 20 years and have never lost a vehicle due to mechanical problems. Had 276,000 on my '04 Tacoma and still ran great, until someone turned left in front of me on a rainy night. Amsoil won't help you stop, but it will help keep you going!
I've noticed it runs alot quieter some how. Cuz my mufflers have been a little loud on my Chevy Impala. I didn't see any obvious holes.
I don't understand it idles quieter.
Passing others has not been noisy either. Just awful good oil.
