07 FLSTC I would like feedback on the proper reading of the oil level. The manual indicates to set on jiffy, and top off to full mark. I have found that when I fill to the top and then take a good ride till hot, the SYN3 oil expands enough to cause some performance degredation. I have also noticed that the overall level when hot is above the full mark. However, a cold check on the stick shows much less than full, but between the add and full marks. I have also noticed on a fresh oil change with SYN3, after priming filter and adding to about 1/3 full, then running the engine, the level is less than full, but after a long ride till hot, idle for 2 minutes, and checking, it registers at the full mark. What do you think?
