Slowly racking up the miles on the oil while monitoring wear and oil condition to determine the best interval for this freakin Rotary engine.
Only 4 quarts drain out during an oil change. Total sump capacity is 7 quarts, so 3 quarts of old oil remain and instantly contaminate the new oil... it sucks, but what can you do?
Thinking of just calling it quits @ 1,500 mile OCIs. My cost per 4 quart drain n fill = under $10 and takes 5 minutes. Seems like a no brainer since my goal is to try to keep this thing spinning happily for as long as possible. Thoughts?
