It's probably more beneficial to sludge-prone engines (I know one of my cars is on that list) but I was wondering if it would be good practice to use it on our oilheads let's say 100 miles prior to an oil change. However, given the design of our oilhead engines, I have some concerns about altering the oil properties and potentially affecting critical parts of the engine. I could be wrong, though.
