Update: I checked all my vehicles last night just to make sure and all are fine. My blue KJ is my daily driver and even so only has about 39K miles on it. My daily commute is short and i average about 100 miles a week. No funky residue to be found.
My wifes KJ has around 11K miles on it and most of that is from trips to Moab, the Rubicon and AZ and to trail heads around here. Very little of those miles are commuting miles. It was switched to Amsoil just prior to our trip to Moab last year in March after buying it and it still has the same oil in it. It had 4700 miles or so on it when it was changed. there are No signs of the goop in the oil filler or cap.
The also checked our 05 Scion XB (Toaster), bought new in mid 04, and has had Amsoil in it since around 7,000 miles (first couple changes were free from dealer) and it now has about 27k on it. It is used the most for running around town on short trips, etc. and it shows No signs of oil goop.
I agree on the above about overfilling. Not sure if that is what is causing the problem as I doubt that many have overfilled and I know that wasn't the problem w/ mine when it did that w/ Mobil 1. BTW, I certainly am not blaming Mobil 1, just noting that I had the problem early on when using it and don't have it now.
JJ you also live in desert, so that could have something to do with in. Out here in Ohio and Michigan it is substantially more humid and alot wetter. We often go a whole weeks where it never really stops raining. Roads remain wet and the sun doesnt come out.
I wonder if climate has a lot to do with it. For example, I've never seen it happen to my Jeep in New Mexico, even with lots of short trips. Here in Ohio it happens alot, especially if I do alot of short trips.
I've had it just as bad as depicted and my engine is still running strong.
