This might be a silly question, but I can't help but be curious. I changed the oil in my 2000 C10 about a month ago, replaced the filter, and added 3 QT 6 oz. Ran it and checked for leaks, let it sit about 5 minutes, and checked the level in the sight glass-it was just above the full mark. I haven't ridden it since, but when I checked the oil level today, the sight glass was almost empty. Just a hint of oil at the bottom. Still no sign of visible leaks, no sign of smoke at start up even tho the bike just turned 100k on my way home from AIMExpo.
So, did the oil 'shrink' with the cooler temps? Where did the oil go?
