Since I use amsoil in everything else I own I decided to switch my zero turn mower over too. I ordered 2 quarts for my lawn mower and 2 quarts for my generator and they shipped it for free. Love the free shipping!!!
Bottom Line
Yes, I would recommend this to a friend.

Its more than oil- somehow

Ok - so lets start off by saying the mower this is about had its first oil change using name brand oil … it was amsoil. Just because it sounded cool on an impulse buy.
So now the part that matters. We noticed immediate differences right away. It was waaayyyyy easier to start. The mower ran smoother. I could hit whatever i felt like. I just couldn’t kill the mower. It just kept kicking ass for another 30 min on the tank too.
I have no idea how this stuff slams so hard on dollar store oil.
I’m glad i bought a lifetime supply. That gallon jug is a keeper.
And the stickers on the mower? Hell ya.
My neighbors electric mower? Idk i cant hear it. It feels like winning.
I have been using this oil exclusively since last year in my generators. It stays cleaner and lasts longer than the oil I was previously using. I love the protection it gives.
Overall been using AMSOIL for everything since 2004. Have not had a single engine burn oil or break due to mechanical reasons. Purchased my riding mower with Kohler engine new in 2016. Been using small engine oil 10w-30 since new. Engine Still works great and does not burn any oil between oil and filter changes.
I have a Honda engine powered Zero turn with approximately 1200 hours. It was purchased 4-26-2003. I have been using this oil for about 10 years. I use no oil between oil changes. There is no smoke on start-up or while running while mowing. I haven't sent oil sample to be tested because I don't see any kind of wear issues. The next door neighbor is now using it in their new Z-turn mower with a Kawasaki engine. I am very happy with this oil and highly recommend it!
So I ordered this and the filter for my 3 year old cub cadet zt1 50 with kawasaki fr691v engine. After this, no more smoke, ive noticed a literal temperature drop (thermal gun) and it just sounds better overall. Couldn't be happier.
The top engine rebuilder's said this is the Oil with zinc for the air cooled engines. These engines , air cooled need zinc! I use this oil in all 15 of my Gravely Kohler , Vnaguard and Onan engines - they work hard summer and winter!
Bottom Line
Yes, I would recommend this to a friend.
