I know why I can't read it, the oil is too clear. I got this a few months ago from my son in law, it was given to him from a friend who claimed it seized and would not start! A few weeks later I charged the battery and tried to turn it over, it did turn over but sounded strange. I drained the oil and it had 5 quarts of what smelled like gasoline! Google informed me that some of the older Craftsman with NIKKI carburetors had internal problems and since the gas is gravity fed it would continue to leak past the internal parts of the carburetor and into the crankcase. My 2006 Craftsman with a Kohler carburetor did the same thing about the same time as the 1997 Craftsman. So that is one thing we can't blame on the crummy NIKKI carburetor.
Now, the point of the story is there I was with 2 Craftsman tractors with fuel in the crankcase. I drained both engines and I ignored them for about a week while they "evaporated" the fuel while I turned them over a few turns every day and rebuilt both carburetors. Then I replaced the oil filters and oil. They both started and I let them run about 1/2 hour each and drained and replaced the oil and filters again. Now I have oil so clean I can't read the dipstick. I have run both engines quite a bit since that time with no problems although I do expect to be adding oil since I am sure there is some ring wear while using diluted oil.
Question, is there something (color) I can add to the oil so I can feel comfortable I don't have fuel running into the crankcase. I did add fuel cut-off valves to both fuel lines!
Finally, I have a question: What can I add to the oil so I can read the dipstick?
