Customer Ratings & Reviews

I purchased 6 bottles of this oil to try it. I really don't know how you can tell if it's any better than any other name brand automotive oils in small air cooled engines. I've been using Classic Car 10W-30 oil or 10W-30 Racing oil in my 4 stroke small engines for many years that contain higher levels of zinc without any issues or problems. These oils can't be used in cars with a catalytic converter as the higher levels of zinc known as ZDDP will destroy the converter. I probably won't buy this oil again due to it's very expensive cost plus I'm not convinced bottles labeled "small engine oil" is really any different than regular automotive oil!

Purchased this for my power washer. Decreased the sound noticeably, for a machine that works only at max all the time. Even after extended use oil is still clean, motor is quite. I believe this to be a good product for long term preservation of your equipment. Right now 20 hrs in, after the change.

Changed the oil in my two lawn mowers and noticed a difference in the sound and smoke when starting. Will be changing the oil in my John Deere lawn mower soon and hope to have the same results.

Peace of mind for all your small engines. I use in lawnmowers, log splitters, generators, etc. Makes cold starts a breeze too.

First time using in some new equipment and some older equipment. It may be in my head, but I swear, my old John Deere garden tractor starts easier, runs smoother, and is quieter, if that is possible. My Scag commercial mower also starts easier. I will be a customer for life as a result.

My spouse prefers synthetic oil in all equipment. This is our second year using for all our small engines and without a doubt very good. Also notice the oil seems to stay cleaner throughout the season. We have always had to replace synthetic oil after every season use when using store bought oil. Some of our machines still had fairly clean oil ready for another season

This oil is the best for small engines. Keeps engine protected and clean especially in high heat climates.

Great product 👍

I use AMSOIL in all my small engines. cleaner burning and great protection!!

I use this in every small air cooled engine I have.

Product comes highly recommended for small engines is what I’m using from now on.

This oil may be overkill. I've used it and my engine on my 22 hp Kohler engine on my ZTR for 13 years. The mower rusted out, but the engine runs like new. I was able to re purpose it for another application.

Use in all my generators , push mowers , power washer , roto tiller , snow blower and Lawn tractor. Engines perform and sound as they did when new. I use nothing but Amsoil in everything that reciprocates or rotates.
