Excellent , safe way to check oil level... Thank you....
One more question, why in the world is my friends new F6B say in the manual 3.9 quarts of oil (with filter change) and the Valks say 4.1 Quarts of oil (with filter change)... I thought drive trains were same...
There are two basic oil filter sizes that fit. Unfortunately, I don't have my list in front of me, but it's the length of the two filters that is different. Different by about an inch.
1 inch of filter will make 0.1 or 0.2 Qt difference in oil capacity.
If I had to make a guess, I would say the Valk uses the longer filter in stock form, thus the difference between the manuals.
However, the engines ARE the same and either of the two lengths will work fine.
