I bought my 2009 Nissan Maxima with 103k miles when it had 80k miles. It was one owner and in pristine condition. %95 of maintenance was done at a Nissan dealership in PA. I have at least 15 documented OCIs most of them done at the dealership ship with what listed as "Nissan 999BK05w30NW" oil with Nissan filters.
I've done DIY oil changes since I got it using Nissan filters. Used Amsoil SS 5w30 once, 2 PUP 5w30, once or twice M1 0w40 and last 2 OCIs with M1 EP HM 5w30.
It "burns" about half a quart every 2k miles or so. PUP was fastest to burn. Which steered my away from it entirely.
But what I noticed lately that the rate of burning goes down the farther I go in one OCI(and rather consistent in each OCI). Example I'm now at 2k this OCI and it seems the rate of burning is less than say during 1st 1k miles.
Any explanation of that?
