Now this is weird. I've always used Castrol 20/50
in all my LBC's. I had just changed the oil prior to
the Carlisle Import Show trip.
On the way home from Carlisle...we (Gail and I)
noticed the oil pressure was a bit low. Warm, it
was max'ing out 40 psi. And yet at an idle, it never
really went below 20psi.
I was beginning to believe maybe my oil pump had taken
a nose dive. So today, I put in a fresh supply of
Mobil 1 15/50. Wow! Now considering the old 20/50
Castrol had less than 150 miles on it.... why would
the Mobil 1 push my pressure right back up to the
80-90psi range cold?
Right out of the bottle, the M.1. 'swishes' around as if
it's thinner than what came out of the crankcase.
...stumped here....
