Re: [Amc-list] Oil Protection - ZDDP or Bust -

["Armand Eshleman" <aje1@xxxxxxxxxxxxxxx>]

Probably not unless you are enjoying the car at lap days at the local road
course, or maybe using the
engine in a tow vehicle. The oil usually is OK if the engine temp is OK. We
of the road racing persuasion
employ oil coolers to keep the oil temps below the oil breakdown range, but
our engines run between 4000
rpm and peak rpm for 30 minutes to several hours.
Just my opinion,
Armand
