Hi guys. Thanks for your answers so far.
Mike, the oil was changed about 3 weeks ago.
John, my engine has maybe 40k on it since it was rebuilt. Anywhere above idle it runs about 55psi cold or hot.
The only other thing I can think of are that I now use 10w30 since Jiffy Lube doesn't carry 10w40 or 20w50 anymore.
