Neither do I. 99% of my driving is 50mph and under and definitely not what I would deem harsh driving. I have taken it down several dirt roads fast, but never redlined or anything.
Even cars that I have truly "beat up" on havent had oil consumption problems. Only oil-related failure I ever had was a Sentra with lots of miles that burned a quart a week. But I only paid $400 for the Sentra.
I agree with fyboy about the readings, mine are virtually the same hot or cold too. It dont take long for the 0w20 to drain down. Hell youre supposed to check it when you gas up. no way to do that cold!
