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!
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.

It was a very simple process to order from my phone and got the product when expected will be a repeat customer
I've been using this small engine oil for years. Cost's a little more but it's a lot cheaper than a engine cylinder rebuild. Consistency holds up like no other. You get what you pay for folks and Amsoil is #1 in my book.
Bottom Line
Yes, I would recommend this to a friend.
