Anyone Use BG Products Engine Restoration Before

Agree, if you had blowby or burning oil, it may be worth it. But there are enough of these (and most types of) engines running well with a pile of miles on them to tell me that this is not needed.
Keep the fuel well filtered (2 micron) and OCIs and party on. The rest of the truck will need work everywhere before the engine should need anything internally.
Cheers!
