Has anyone noticed if on the 20I the oil guage on the tach instrument works or if is even supposed to work as an oil level guage? I have always kept my oil tank full so just assumed the 3 bars stayed lit because it was full. Now I am at aboout 1/4 full but the 3 bars are still lit. I can only assume it is supposed to keep track of your oil level not just sit there doing nothing.

Thanks, John.
