Hello guys, I have a question concerning the looks of the oil on the dipstick. I have a 05 caddy cts with 102k miles. Its the second time that I do follow the OLM on the car for the oil change and right now, I'm at 9% engine oil life and almost 10k on the oil. I use M1 5w30 gm4718m specs only. When I check the oil level when the oil is fresh up to 9k miles approximately, the oil stay on the dipstick. But yesterday with almost 10k on the oil, I found something weird. On one size of the dipstick, the oil stay on it, on the other side, its the same thing as if the oil doesnt stay in place. I dont have a picture but check this one its exactly how the oil is on the dipstick looks like like water dripping from a window. Is this normal?
