I want to get as much of the old crappy gunky engine oil out of my Ford Ranger before I replace it. Do these engine flush additives actually work? If so what's the best one for a diesel engine?
That’s what my mechanic always said to me...Before you replace the engine or the oil ?
There is the risk that any so called flushes...could dislodge crap to places it should never be dislodged. So just how bad is it inside ? And is there really any reason to tempt fate over a good warm oil change or two ?
