Just another comment and question to add to this huge thread. I agree with Sandra that the oil viewing port on the motor doesn't work very well because the first thing I did after reading her post was to check mine with a flashlight. I've checked it before also. My motor is mounted upright in my garage but it is really hard to tell the correct level viewing through the port window. The oil is so clean that it is almost clear. Has anyone tried using a synthetic oil that has the red color added to it to make it easier to see? Or is there something that one could add to the normal oil to color it? Engine/Motor experts please let us know. I have learned so much from this BB and look forward everyday to reading the daily posts. The people here on the BB are just just great! Maybe someday I will share some of my really stupid mistakes that I have made (when I get over the embarrassment). It seems we all have the stories. Thanks everyone, Peter Peanut M15 #618
