Not Marauder specific question but I am hoping someone knows the answer. I have 3 dipsticks and tubes in my possession. One out of a Crown Vic with 4.6, one out of 2006 Navigator with 3v 5.4 and a Lockar made for both 4.6 and 5.4.
When laying them out side by side they each one shows different oil level in the pan. The 5.4 3v Navigator dipstick reads an inch or more lower than the Crown Vic dipstick. Lockar reads the highest of the 3. I was under the assumption that all Modulars should have same oil level. So, what gives? What should the correct level be from the bottom of the engine block?
