I tooo am a big fan of synthetics, but only on new engines(rebuilt as
well). In fact my older cars (ok most all of them) run on Pennzoil crude
base oil. Why?? No I don't own stock in the company, the reason is that
it is a good oil that does not have the high detergent content of
Valvoline or Quaker State. Now that Pennzoil has been bought out this
may change, but I cannot recommend Synthetics in a used engine, unless
all the seals in the engine are renewed. This comes from a guy that is
sponsored on the track buy a synthetic oil manufacturer.
