After using this product for the last 2 oil changes on my zero turn, the oil bow comes out looking almost as good as it did going in. Very happy

As with the other Amsoil product I use this one did not disappoint. I use it in my lawnmower, generator, and other small engines and makes them all run much smoother. I love this product.

Used this oil in my backup generator at home. I change the oil in it once a year, if it was running a lot or not. Oil is clean and the engine in the generator is smooth and quiet.

I use this in my generator and it does an outstanding job!

Great Product. And Fast Delivery....

i use this oil in my standby generator w/ kohler engine. it works great. runs much quieter and very smooth now.i really like this 5w30 during the winter months, its nice knowing amsoil is protecting my engine during this harsh time of year

Purchased this oil for the generator in my motorhome. Noticed a big improvement in the way the engine runs. Smooth and steady. Great stuff!

Put this in my Cub Cadet Edger AND my Stihl pressure washer a few weeks ago. It quietened down my pressure washer so much I thought something was wrong with it. And when I pulled the trigger on the wand I noticed it doesn't pull the RPM's down near as much as it did which tells me it has more lubricity than my old oil! No, it's not snake oil but it's good stuff.

This oil is amazing for keeping older 4 cycle engines alive. I'm sure it's great in new engines also, but if you don't want to have to keep replacing your power equipment every 3 to 5 years, just use this instead. I use this in my 15 year old lawn tractor, and my 10 year old snowblower. By the time the wheels rust off of them and they are no longer usable, the engines will still be going strong thanks to AMSOIL.

As long as I run the best oil in my bikes, it makes sense to use best synthetic oil in my zero-turn mower too.
