Noticed my XTown has only 1 qt oil capacity....and oil in engine is unfiltered/protected only by screen. Based on about 175,000 mile experience with 4 Honda Helix---about same oil capacity as Xtown, same unfiltered system......and small engines working very hard, I
CHANGE OIL every 1,000 miles---used oil comes out black....meaning additives are working.
What oil do I use? WalMart house brand 10-40. Priced right and works, no engine trouble in the last 500,000 miles or more, scooter and motorcycles.
Looking at Kymco shop manual,it shows only using drain plug for oil drain---makes oil change simple. I think I will look at screen only every 10,000 miles or so.....saves hassle.
