I change the oil on my car myself. I drive about 13k miles a year and currently I have 76k miles on the odometer. I change my oil every
7k-8k miles. When I change the oil, I do notice some drop of the oil level on the dip stick, still within the normal range. And believe it or not this is still considered normal, so the engine does consume some oil. It becomes a problem if you have excessive oil consumption, and by that I mean significant drop after say 1k-2k miles, then you have worn piston rings. And as you said if you drive the car hard and at higher RPMs the oil consumption is worse.
I called my local Lexus dealer and they said it's normal. Being slightly paranoid, I put the car on a lift at the corner tire store and looked underneath, no sign of oil leaks either. I'll continue to monitor oil level just in case it's a piston ring or PCV issue.I'd say going over passes at 15,000 feet makes for hard driving... I also remember some oil loss on my previous trip. Good thing it's not an Audi! 😋
