Customer Ratings & Reviews

again and again amsoil make superior products a lifetime customer here have been using their products for 11-12 yrs and no problems they stand behind their products and their products are made right here in the USA

I use in all of my small engine lawn maintenence equipment. One mowing season at a time, means one oil change a year. AMSOIL saves a lot of time and money for engine maintenence. If my equipment is not cutting grass, and is in the shop for simple oil changes, its simply not making money. Time is money, make a great decision as I have and stay out of the maintenance shops.

I use Formula 4-Stroke Synthetic Small Engine Oil in my 1979 Toro snow blower. 38 years old says it all.

Great protection at a reasonable price.

I use this product in all my commercial 4 stroke motors.

It's very convenient to use this oil in my garden tractor since it gets used for mowing all summer and sees snowblower duty in the winter. Don't have to change oil just due to the change of the season. I put on less than 100 hrs per year so once a year oil change works great for me.

I use in my landscape equipment for worry free operation. I work in the south where it is hot and it works great. I've been using for quite a few years now with no problems and I work my equipment hard.
