How much oil drains from the oil pan compared to the oil reservoir when you change the oil? The reason I ask, is when I was complaining to a guy who works at a cycle/marine shop, he said it would be easier to change the oil if I used one of those oil removal pumps to drain the reservoir rather than fight all the drain plugs. His theory is that changing every 3,000 miles with synthetic oil is overkill and what remains in the oil pan would not be a big issue when blended with new oil. He said full oil change service every other or every third time should be fine. Don't know if that makes any sense, but if it is feasible, it sure beats jack stands, breaker bars, crush washers, frying pans and and hour and a half of labor.
