Let's see if I understand this: You're saying Castrol came the
closest to failing to meet the specs?

If so, maybe that's why my Olds engine recently ate a rod bearing.

Hmm, back in the 60's my roomates & I all drove BMC cars, MG's &
sprites; and
they used Castrol & I used Kendall. They had several main & rod brg
failures &
I never did. Could have been driving or some other factors but that was
the
main difference I could see.

I raced a 1275 MG Midget, originally on multi-vis Castrol, and the oil
pressure would drop precipitously as soon as the engine got hot. Most of my
racing buddies experienced the same thing with Castrol's street oil.

They had a single-vis racing oil but it wasn't a lot better. We figured they
must have had a special formulation they supplied to pro teams because we
got nothing but lousy performance from Castrol.

In any case, today's Castrol smells nothing like Castrol from the '60s and
'70s. It must be an entirely different formulation.

We wound up using a heavy-duty Wolf's Head that's no longer available, BTW.
It really held pressure well when it got hot, without being excessively
thick when it was cold.
