07 SL AWD 72K miles.

My last oil change is about 5 months and 6K miles with mobil1 synthetic, 5 quarts poured in, only about 3 quarts +- drained. Previous oil changes may be a little low but not by much, didn’t measure carefully.
Emission test was just passed with no problem. Never had a smoking issue. The car drives very smooth on some days, but a little rough on other days. Going to the dealer tomorrow for a unrelated axle leak. Have about 1200 miles and 2 months left on extended warranty. I see a few people here reported same issue, but no real fix other than engine rebuild. Don't know what if any dealer will offer, but at least have them document this.

Maybe leaking oil around plug seals on valve pan covers that's where mine was

Oh man people around here get upset if you revive old threads like that.... But I like the homemade drip catch can. Reminds me of some old story (no idea if it's true or not) that the death of the british bike industry came about because of poor attitude about innovation and correcting problems. Like rather than figure out the root cause of the problems they had with engine oil leaks, they designed catch pans to put under the bike to deal with it. Then the japanese bikes came along and that was that....

Hi all, my murano started to consuming about 2qts of oil between oil changes. It's a 2007 with 80k and I also noticed it felt like the idle was different. It wasn't missing or stumbling but like it had a bad pcv valve so I changed the pcv valve and spark plugs. I noticed 2 plugs had ash deposits and there was a puddle of oil in the plenum. Afterwards the engine still felt like it did before but oil consumption dropped a bit but not completely gone.

I was wondering if anyone else had any deposits on their spark plugs and if they noticed their murano's idling any different?
