<VV> Oil

[BBRT]

I get a LOT of trade publications in the automotive field. Never heard that synthetic oil wears seals, rubber or otherwise.
Ethanol affects seals.. Reported numerous times plus other ill effects. VITON seals are great for static seals like o-rings on push rod tubes. Not so good for rotating surfaces.

Sounds like an old wive's tale to me. Can you forward a link to the offending article?

I just read in one of those ASK THE EXPERTS columns that synthetic oil can ultimately wear away rubber seals in the engine.  I know synthetic is better for hotter running engines....I was about to put it in my 66 Monza but now I don't know.     Richard Simoff
