I had a friend who almost never changed his
oil, just changed the filter and added enough
oil to make sure that the
oil level was right. His Ford engine lasted for a long time!
I am not advocating that, since I feel the oil gets contaminated with corrosive combustion byproducts and even the oil industry says the additives are the first to go. Every second or third oil change my friend would add a container of Rislone...did it make any difference? We'll never know...he's gone on to that great boneyard in the sky!
Cheers!
