Re: Diesel Engine Oil for older cars?

["Fred Thomas" <vafred@erols.com>]

John, I think this might not be a good idea, our cars may be old, but most
of them have new rebuilt engines, also with the frequency of oil & filter
changes, sludge build-up should never be a problem, STP might be good for a
old almost worn out engine, yet I certainly do not want any in my rebuilt
engine. Just my .00002  "FT"
