Re: Oil Additives
Preferred?
1. I think if one drops the oil pan & removes the valve cover to clean out non-detergent oil sludge, (if any), & replenishes oil with a name brand oil specified by current auto manufacturers; and/or,
2. If one has a new rebuild or a cleaned Model A or Model B engine with good compression & tight fitting rings; and,
3. If one changes oil on a regular basis,
4. Then Marvel Mystery Oil & Sea-Foam are not really necessary unless one has some other unique engine problem.
