Does Mobil 1 5W-20 thicken or thin out as it degrades with use and time?

Wrong forum.

oops, hopefully the administrator or moderator deletes it. I was searching and failed to notice which forum I was starting a topic in.

greg,

Look up some used oil analysis for the Mobil 1 5W-20 oil and see if the oil has thickened or thinned out with use.

I did try searching but everything seems to be for 5W-20 mixed in a brew or with other additives or with fuel dilution but rarely just Mobil 1 5W-20 with lots of miles. I seem to remember the old Mobil 1 5w30 had a reputation for thinning and I was wondering if there was a consensus on the new Mobil 1 5W-20.
