Great product

My preferred choice for my generators. Once I switched the didn’t burn as much oil during use.

Always my go to oil.

I have been using this for a while, both machines run smoother,quiter and they run cooler.I would recommend this to anyone who has a generator.

By using Amsoil, I've noticed better performance and less fuel consumption in my lawn care equipment. It doesn't break down as quickly as other oils I've used, and it has a much slower evaporation rate.

I use this in both my Honda generators.They run smoother and quieter.Also they seem to start easier.

I use this Amsoil in my zero-turn, which is an air-cooled hard-working lawn mower, that works out back on the hard stuff, and not on the lush easy front lawn. I get smoother stops and starts, and peace of mind knowing the level of protection for my small equipment.

Small engines need good oil too. Especially generators which are seldom used. I use Amsoil small engine oil 10W-40 in my generator because I know it will stay good for a long time. Also use the same thing only 10W-30 in my Honda lawn mower. Pleased with the oil.

I’ve used AMSOIL in my motorcycles for years with great success. I used this small engine 5w-30 for my home generator and it’s been just as great.

Since I use amsoil in everything else I own I decided to switch my zero turn mower over too. I ordered 2 quarts for my lawn mower and 2 quarts for my generator and they shipped it for free. Love the free shipping!!!

Ok - so lets start off by saying the mower this is about had its first oil change using name brand oil … it was amsoil. Just because it sounded cool on an impulse buy. So now the part that matters. We noticed immediate differences right away. It was waaayyyyy easier to start. The mower ran smoother. I could hit whatever i felt like. I just couldn’t kill the mower. It just kept kicking ass for another 30 min on the tank too. I have no idea how this stuff slams so hard on dollar store oil. I’m glad i bought a lifetime supply. That gallon jug is a keeper. And the stickers on the mower? Hell ya. My neighbors electric mower? Idk i cant hear it. It feels like winning.

I’ve been using this oil for years in my mowers and side by side, this purchase was for a neighbor that still had break-in oil in his mower

Did a flush with this oil and refilled my old mower. Decided not to throw out the mower since it made it run stronger and better than before.

It works great

I have been using this oil exclusively since last year in my generators. It stays cleaner and lasts longer than the oil I was previously using. I love the protection it gives.

A must have in your garage.

I have used this oil in my small engines, seems to do well. The price point could be better.

Had to pick some oil up for hurricane season. Air-cooled generators work hard in the south.

Arrived as scheduled. Oil looks great and has a smoother texture than standard oil. Lawn mower & generator seemingly run better.

Great oil. Never use any other brand. Thanks AMSOIL!
