Just another lapping day at BIR last Wed.
50 laps on the 10 turn road course = redline in 3rd about 300 times (6 times per lap) and redline in 4th about 100 times (2 times per lap). Result: 150 miles and 1 qt. oil. The perfect result because I added a qt. when I started lapping so I was qt. over and when I was done, I was back to the correct oil level.
GM must have had 50 laps at BIR in mind when they made the pcv system.
I've done about 650 miles of wot at BIR this year and the car uses about a qt of oil to 2000 miles of normal driving (whatever that is).
