[QUOTE=Ed Wright;569241]I was thinking amount of oil. Or, drain back issue. Returns blocked off? Personally, I would try adding a quart.[/QUOTE
My last oil analysis was the last 26 runs from 2017 and that oil sat in the car over the 2017 winter. I forgot to send it in until a few weeks ago and when I got it back it showed 5% fuel dilution. My only explanation for that is a couple start ups in pretty cold weather over the winter with no choke and a very lean idle circuit. I just sent in a sample for the first 31 runs this year and if the dilution numbers are still bad I'm thinking that could be the issue.

The oil is fresh now and if pressure doesn't improve, I'll add a quart and see what happens.
