searching for bubbles on MUD gave me hundreds of threads about bubbles in the overflow tank. On my way back from Moab I stopped for gas, had been cruising at 80-90mph for a couple of hours. When I checked the oil. there were bubbles on the dipstick. It was a little darker than I expected, but then again the lighter color of the bubbles threw me. I will check it again after it has cooled down, but what could this be?? Thanks!
