ust ordered a case soyshield 139A, from Mark. I could not find any thing to read in the search engine. Anyone got anything to add about this product ( good or Bad ) ?
I use it in my tractors and diesel generator. The engines run quieter and smoother with it. Start easier, too. It's a good bit less expensive than Schaeffer's DieselTreat 2000, and seems to work just as well (I've used both). Hope this helps.
