It's that 1.2L of oil to me thats too much to me. And your should be check your oil more frequently. I checked every 500 miles and normally add 1/4 of a quart that equal about one quart every 2000 miles.

 

the dip stick from the first X to the top is one quart, you should just take off the oil filter and drain it. start the car, re open the oil cap close and repeat. then you should be at about 5.1/5.2 quarts.
i keep it at around XXX when cold. when its warm the oil will be around XXXX

 

Expect to burn 1qt per 1k miles driven. Top up and monitor. When you do an oil change make sure the cold oil hit the top x or H. Ignore the hot/cold flux the car was built to deal with the marginal expansion.

I like castrol ti but prefer redline 5w40. Run the 40 if it's 100f+ out and you drive hard. Otherwise 5w30 is good stuff.

PVC might need cleaning but more often it's how you drive north of 5k revs and expect to increase burn rate.

All good motors burn oil to "protect" themselves when pushed to the limit.

Whatever you do dontt stress just monitor and name sure you're never below half way between L and H.

 

I was over way more than I thought and drove it back to my friend's house (2 miles round trip) to drain oil from the filter. I repeated your steps 4 times and now the oil is directly at the "H" line. Before the car was idling bad but since the top of it seems to have helped it. I guess Castrol Edge is going to be my main oil from now on until they discontinue the oil. Thanks all for your help and hope this can benifit other newer owners like me!

 

2004 model here, no oil use at all between changes, which usually range 4-5,000 miles with costco chevron 10-30wt oil. I check every gas station stop, or 260-280 miles. Never been any use. 60,000 on the odo and 8 years of ownership already. I must use some, so i can say less than 1/2 quart between changes.

 

2004+ models are honed with a dummy head attached, and have a different PCV design; they don't use oil like 2000-2003 models do.
