Your usage is normal for an AP1, but a little unfortunate on a 2006 AP2 motor, as those had a dummy head installed during honing, specifically to reduce consumption.

The XXXXs on the dipstick are about a liter, so if you're at the bottom of the X's you'll need to add 1 liter...the oil is FAR from empty, and it's doubtful engine damage would occur except maybe doing laps on a track. It's when the oil level is lower than the dipstick that causes problems.

My own car's oil usage is similar to yours. I'm not sure if it's my rings or a valve guide, but I don't drive the car very much so it's just a minor annoyance on what I consider a great car. My car is 14 years old and makes great power, there's no way I'm going to tear it apart to reduce what used to be considered light oil consumption

You can rationalize it sort of like this. All S2000's consume oil...every car does. Even if you burn none, you'll be consuming 5L ever 10,000KM since you need to throw it out anyway. Yours may consume 10L using that metric. It's annoying, but not the end of the world.

Since your car is an AP2 with the improved F20C, you may very well have luck replacing your PCV valve, and that's cheap. 2nd most likely it's valve guides. It's much less likely to be an extremely expensive fix like new rings, since your car is vastly improved over mine in that respect.

10w30 oil synthetic or not. Change it every 3k if conventional and every 6k if synthetic. I use Castrol Synthetic Edge. All s2ks burn a bit of oil. I have 92k on mine and use about 1 quart every 3k miles

Have you used a 10/40 high mileage oil yet? If not and you have it where you live I'd try that next and still do the 10k oil change. Every time you add oil you replenish the add pack of the oil, its not like the oil that gets burned away is only the good stuff and whats left is all the crap that the rings let by. I would rather go more miles on the oil on a car that I have to add some oil than one that I don't.

10k Kilometers(6200 miles) is not to long, if you want to know for sure you can get a UOA and that will tell you how good or how used up your oil is.

Hello again.

I changed the pcv valve to a new one and there was no change in the oil consumption.
the problem is now more oil is burning does it make any sense?

Thanks!

Maybe, the engine is wearing out more, or the ambient temp is now higher => quicker thinning of motor oil.

Is the car burning oil or venting oil? Without a catch can there's no real way to tell. It sounds like a lot of oil loss.

My experience. Your mileage may vary:

I have an '06 AP2 (2.2 liter) with 48K miles on the odometer (up 10K since 3 Jul 14 when I bought her).

Every time one of these threads comes up I rush out to the garage and pull the dip stick! Oil level after sitting two days is right at the full mark.

Oil and filter was changed 4830 miles ago (call it 5000 miles). 5.1 quarts of oil for the change. I bought 6 quarts for a complete fill and have topped it off periodically so I've lost 0.9 quarts in 5000 miles. Hardly an "oil burner!"

Oil is Royal Purple Synthetic API-SN 10W-30. Spec for these cars is 10W-30...

I have a strange one with mine. If I thrash it no smoke at all. Put driving gently and then pull into traffic it starts pluming out of the exhaust definately oil. Until thrashed again

Sounds like valve stem/seals. High vacuum (like at or just off idle) ---> oil sucked through valve stem seals, into combustion chamber, out exhaust.

Low vacuum (like at wide open throttle) ---> not as much oil passing from valves & heads. Oil consumption at WOT prolly worn oil rings.

Just bought a tool to do them in situ

I burned a quart in 200 miles before my oil change, changed it with castrol edge, haven't burned a drop in 500 miles, no smoke or oil smell anymore. Just keep checking your oil as long as you make sure it's filled your car will run.
