Very good oil

My wife talked me into buying 2 scooters to putt around the countryside. They are only 49cc engines but since I changed the oil to synthetic they picked up a few miles per hour. I believe synthetic oils are great for any moving metal parts. No wear, No friction, saves money in years to come and makes my engines very dependable.

Amsoil oils review

I have used Amsoil oils for the last 15years on all my toys. Never had a problem. These oils are prime quality at a reasonable price.
You can't go wrong using them!

The only oil for my mower!

I bought a new riding mower and wanted the best oil I could find for it. I found the Formula 4 Stroke small engine oil and liked the fact that it was specifically designed for small engines. This year has been very hot and the grass has grown like crazy so the Amsoil has been put to the test and passed with flying colors. This is the only oil I will put in my mowers from now on.

Quality alternative/peace of mind

I use the formula 4 stroke in all my small engine equipment: pressure washer, lawn mower, engine-driven air compressor, brush mower. I feel it's a quality alternative to brands at local parts stores and it gives me peace-of-mind for longer oil change intervals and severe duty service-just as intended.

Best warm weather oil for outdoor power equipment

We use Formula 4-Stroke in our commercial lawn mowing business...45 deg F to 100 deg F. It is proving a great oil, no consumption, engines still running like new, and the oil still looks fresh at the OCI. At the 10w rating, it will be fine for cool weather mowing. I'd use the 0w40 formula for severe winter OPE use.

Great small engine oil

I use this oil in my 36 inch walk behind mower, the snow blower and a permanent outdoor standby generator. These small engines are still full on the dipstick at their annual oil changes and the oil looks clean. All of this power equipment is now 10 years old and they are still going strong. Thanks for making such a great product for small engines.

Excellent protection, as you would expect!

I use this oil in my walk behind mower & lawn tractor. One change through the season with about 50 hours on the work horse lawn tractor & the oil is still still clean, I almost feel wasteful when I change it.
However, I know better. I've used Amsoil for the last 12 years & have not been disappointed.

repeat buyer of this oil

I use this oil in riding and push mower with no problems and know its of the same quality as the automotive oil. I've found Amsoil to be a very reliable especially when I lived in the midwest and will continue to run Amsoil is all my vehicles. I give two thumbs up to the Z-Rod oil as well my '62 Galaxie sure likes this oil.
