I use my small engine (4 cycle) in temps from the high 30's to over 100 F. In air cooled engines this great quality oil gives me the protection I want. Great results in multiple Kohler, Kawasaki and Honda 1 and two cylinder air-cooled engines used in harsh conditions.

After seeing great results with my truck and the signature series oil I had to try this. I used this in a john deere x580 and it seamed to quiet the engine. I recently traded the deere for a new Scag Cheetah 2 and after break in I wanted the best oil I could get for my new toy. It seams to be doing well.

I’ve been running a Honda eu2000i for 24hrs a day 3 years straight. I shut it down once a week to change the oil and that’s says something

Great product, fast shipping.

I have been using Amsoil small engine synthetic oil for my 77 John Deere garden tractor. I'm picky about oil. I've had this JD 210 since May of 78. I'm the original owner and the k241 Kohler has yet to be rebuilt. I've mowed a lot of lawns and plowed lots of driveways over the years. My motto is if it's not broke why buy a new mower. I like the Amsoil 10W40 synthetic small engine blend. It provides fast starting in winter conditions. You can tell the difference from conventional oil which has an increased start time under cold winter conditions. In the summer time it delivers the power you need to keep things running their best. If you wonder about changing your oil think about this. From the beginning this tractor had its oil changed twice a year. It gets an oil change in spring and one just before the snow hits. I don't know how long this K241 will last but it's been going for 44 years now. Changing your oil and filters is key to longevity . Amsoil delivers .

I’ve been using AMSOIL for a very long time. At least 25 years. In cars, manual transmissions, motorcycles and lawn mowers. It doesn’t look like I will stop using this oil in the near future.
