I suspect most old car guys are familiar with Seafoam. Though I can't recall exactly what is in it. I've always used it as an additive for gasoline engines - boat fuel, mower fuel, oil mix for power tools and the outboard. I think of it as a better alternative to Stabil.
Can't say as I've ever thought about it as Diesel additive, or added it to engine oil. Might be a good thing to check out.
