Today I lowered the oil level to 3/4 on the dipstick. I read some post somewhere that having too much oil in the crankcase caused a guy poor economy. I think he said that the manual even says to do that... doesn't sound right, but I'll try it.
I believe I would rather have poor economy than low oil, but thats just me...My scooter only holds .9 mils of oil and I want it all in there.
