How do you measure the oil level?
With the stick screwed in or just sat on top?
The difference is probably the top and bottom reading on the stick
How ever you decide to check your oil, you've got to just do it the same way each time. You can get two different readings if you vary your method by two minutes.
The dipstick on my '08 AVL has hashmarks between the Hi & the Lo. Very easy to rub a little chalk into & see the level even with brand new clean oil. Screwing it in or not screwing it in is a very small dimension on the dipstick.
My engine likes to be checked about two minutes after being shut down. I like it right around the 1/2way or just a hair more on the hashmarks. I get VERY little ever out of the CC Breather which ends (with a duck bill) in an old DryGas bottle sprayed black & hidden right in between the frame tube & the front of the rear plastic mudguard. It's barely even noticeable.
If I go down right now early AM & check the oil without running it, there will be NO oil showing on the dipstick.
