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.
