I've seen many different tests over the the last 20-30 years and Amsoil usually comes out on top and if not, it's second. No other oil ever tests that well across a battery of tests.
It's why when someone asks what's the best oil for xxxx, I have no hesitation saying Amsoil.
I have used Amsoil for 20-30 years in everything, 2-stroke oil (Actually passed the tests at 200:1 or 300:1 ratio but the engineers decided no one would believe them so they just called it 100:1), Diesel and Gasoline fuel treatments, greases and obviously oils and filters for Jeeps, cars, Diesel pickups, multiple ATV's, Zero Turn mowers, Push mower, Pressure Washer, Edger.

Not necessarily. Amsoil synthetic can be ran a lot longer than the non-synthetic oils and even longer than many other synthetic brands.
"Guaranteed protection for up to 25,000 miles or 1 year" for many Amsoil motor oils.
Amsoil doesn't cost much more per quart/gallon if you're a Dealer or Preferred Customer (PC) so actually over 1 year you can save more money using Amsoil, even factoring the cost to be a PC.
Then there's the added benefit of knowing you have the best protection available for you engines if you use them in high temperatures or very cold climates.
