I was going to get UOA on my previous oil change but have a couple of questions.
I drained the oil and it was sitting in the pan for about an hour. I then collected some in a clean pickle jar from the top of the pan (i.e. did not stir the pan).
The jar has been sitting in the garage for 2 months in a dark place.
Is this a good sample? I am wondering about stuff settling in the pan also after a couple of months in the jar is it possible some things (fuel?) has evaporated???
