Yes: It's actually says SoyPower on the gal jug.
I still will order the Opti-Lube, and use it along with the Soyclean. I live in the heartland of the States and I have alot of relatives and friends who grow soybeans, for a living. So I am going too use both.
I will mainly use the Soyclean, since it will support the families around me. Don't get me wrong! I feel Opti-Lube has an outstanding product here. I will continue to use it.
I will probably switch back and forth ea month. I all ready have converted alot of diesel owners within my area to switch to the Soyclean, instead of the in store brand additives. I have heard nothing but praise about this product. Everyone has their preference. So everyone will have an opinion. This is just mine. Opti-Lube and Soyclean both have preformed well within my 7.3L Ya can't go wrong with either one. Again-->This is JMHO.
