As I get older, I’m finding that my memory isn’t as good as it used to be. I used to have a 2008 C14, put 111,000 miles on it before my accident. That was 4 years ago. Now I’m back in the saddle of a 2019 C14 and I’ll be damned if I can remember this one dumb question….When changing the oil, do you check the site glass level with engine running or off? I put in the required amount of oil but I’m a visual guy, I like to double check.
