Great product at an affordable price.
I use this product on my home Honda generator. It works great and is fairly reasonably priced compared to some other offering.

Makes mower easier to start
After changing to this synthetic oil, my Honda mower starts on the first pull and seems to run smoother. Great product at a good price.

Good oil for lawn equipment
I thought I was buying full synthetic... It is a blend. I needed more oil and I ultimately decided to keep it as for the use -- it will be fine. Usually I use Amsoil but my local shop sold out to a larger fish and they stopped carrying the product line. I know this is a big jump between the two, but I do change the oil annually and for my mowers, power washer, and snow blower -- this worked just fine for this time around. Next time I will be going back to my preferred Amsoil small engine full synthetic oil.

Does the job for a great price
Seems to work great so far in my cub cadet lawn mower. The price was great and the convenience of shipping it when it was in my mind was the key. I don’t anticipate any issues but so far it has worked perfectly.

Great Syn Blend!
Some of the best for high revving 4-cycle Honda engines. I use it for my snowblower, power washer and Exmark mower with Kohler Commercial engine. All run great with this syn blend!
