So jello stated tapping today on the way home.... 30 minute ride. No lights, just a tap. I just went outside and the do stick is bone dry. Will get oil in the morning and PRAY until then..... Oil light never came on..... But sending unit might be defective...... Time will tell..... How low is it when it's not in the stick..... I know at the bottom is one quart... Surely if it was empty it would have locked up on the way home at 60mph for 30 miles?
