Has anyone else noticed a tendency for M1 5W-30 to get burned off while racing?
I made a good 11 passes at the track yesterday (44F-48F) and this morning the oil was low by 1/8 to 1/4 of a quart.
When I made 7 passes last summer (90F temperature) with dino Chevron Supreme, I didn't lose a drop of oil.
The only thing different about the engine is that I went to a set of aftermarket camshafts for a Ford 4.6L SOHC V8 (12,800 miles - bought new in 2000).
