Thanks Rick, you're always a wealth of knowledge.

I too have had several engines go over 200,000 miles, I think mainly because of my good maintenance. And that's with no,....additives.

"THEY WANT TO KEEP SELL NEW PRODUCTS!!!!"

You're correct. I feel the same with rust on bodies. There's no doubt they do the same with all the parts on vehicles, otherwise there would not be any need for the OEM or aftermarket replacement parts and put a lot of people out of business, including me !
