Further info... Just a short trip to the store tonight and I got the low oil indicator light. So apparently the oil filter is NOT the culprit.

Twice in a row the oil indicator light went dark while cornering... not sure if that's coincidence or not. Unfortunately by the time I stopped the oil indicator light was out. No oil had been unceremoniously vomitted.

I'm considering putting the vacuum/pressure gauge on the crankcase vent or the oil dipstick tube to monitor while driving.

Thoughts?

Bill
