John Kmetz Sr. uses Lucas Heavy Duty Oil Stabilizer in 1984 Plymouth Voyager

I have a 1984 Plymouth Voyager with a lot of hard stop and go miles on the engine. It was a delivery van for the bakery where I work before I bought it. Well as of about a month ago it started really running ruff, and I noticed really low oil pressure. So my friend at the auto parts store suggested I add your product with my oil change, if I didn't see and hear the diff. myself I would have never believed it. I used to work at a automotive parts store myself, and always recommended that other oil additive, no more. Great product, think I will try your fuel additive next. Looks like old blue (my van) will live at least a few years longer. Thanks a million times.
