Is diminimous.

This is a new record low for me.

This is in 9500 miles of mixed city and high speed driving consumption of Penzoil Platinum 5w30

105K miles on the car.

Ill measure how far down this really is at oil change time 500 miles from now, but I'm guessing its about a pint or so.

Pretty happy with this performance.

Nice. What oil? At 98,000 miles, over 5,000 mi. intervals my Cruze uses zero. Same on the few 7,500 mi. intervals I've done.

Perfect time to change the pcv valve with an oem unit and run an interval or two of High Mileage oil. Take your pick on which one to run. Probably stick with Pennzoil HM synthetic or Vavoline SynPower with Maxlife.

I wouldn't worry with that interval.

PP 5w-30

Sounds really good, but I imagine with such a low profile vehicle the running load on a car like that is quite small.

Usage was effectively undetectable until about 7500 in this case.

I had 2 1K trips up and down the state on the 5 freeway in searing 100+ heat with a mountain climb at the south end and those trips saw the "increased" consumption.

I'm unsure why I would want to change anything.

Yes and no,

Between the 2 holes is easy, but there is a barely perceptible line in the metal under the top hole. (where I drew the top red line)

This is the oil level where the recommended factory fill amount ends up.

Yeah Justin, Im thinking about the same.

That's very good for almost 10k miles! Wish my Kluger would only use that much. I definitely wouldn't change anything either. I'd try high mileage stuff if it used that much in 1000 miles.

Thats 1/4 to a 1/2 quart max. If this is the first time you see this and have run pennz 5w30 previous 2 changes, I would swap the PCV valve. It might be the only thing causing the very slight usage. Yes its barely anything over the 9500 mile run but still..if you have never swapped the PCV, its a cheap thing. If you choose not too, so be it. Still barely anything.
