[s-cars] Length of S4/S6 Turbo Life

[tblack]

My '93 has 214000km. and is quiet and still gets 1.1/1.2 bar of boost.
Everything dead stock. An Audi mechanic who I respect estimatedthat
250000miles (400000km.) should be attainable with Synth oil changes every
6000km. I use either Castrol Syntec or M1 10-30. New filter at each oil
change.
My $.02 on a quiet Wednesday aft.
Tom Black.
