Quality of the product of course. Very dependable everything's so expensive now excellent product
Highly recommend. I used to build small engines. And this oil is the best I've ever used. I've probably tried at least eight different products and this is the one I've been buying for The Last 5 Years.

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.
