I have used their oil (synthetic blend) and also I am currently using their fuel treatment. I don't use the oil now because there is not a dealer local that will sell to me on orders less than $250.
I like the fuel treatment(I bought 5 gal. from my dad) and have been using it for the past 2 years. I have a cousin that is a dealer in south Arkansas so that is where I got the treatment.
As far as the oil. . its suppose to be good stuff. .
They have a citrus degreaser that is top notch... .
