Mobil One is an exceptional product that anyone would be wise to use - no matter what anecdotal warnings you will certainly get. I'm persuaded that it's a benefit in any car - except for museum pieces....:) PC "ajames" <ashleynopsamifi.co.uk> wrote in message news:tq778to9ecqp47nopsam.supernews.com... | Rolls Royce recommend Esso Ultron synthetic oil for all their cars that have | had an engine rebuild.
