I have over 2000 miles on my moped and I just used the last of my first qt. of oil. I’m sure your car is spewing out more poluttion than a moped.

Does your oil mix with and get ignited with the gasoline? That’s what happens with a 2-stroke moped engine. Some unburned fuel and oil also leak out with every cycle of the engine.
My car, if i had one, might be said to “burn oil,” but the oil isn’t part of the combustible fuel. I suspect that when one says a car “burns oil” it means that the car loses oil via other means: oil breaks down, leaks, perhaps evaporates…
In any case, the linked Wired article states Vespa engineered a 4-stroke moped engine that solves that problem.
Also, you’ll note that newer lawnmowers are frequently if not entirely equipped with four-stroke engines for environmental reasons.
[QUOTE=Johnny L.A.] Gas mileage: My R1 gets almost 40 mpg. My 600cc XJ-600 gets 50 mpg. So IMO a 600cc motorcycle is better (mileage vs. utility) than a scooter.

You get 40mpg with the R1 ? :eek: The best I’ve got with the R6 is 30-35 mpg. It drops to 25 when I am pushing it really hard. My R6 is a 2000 model (carburated). Is your R1 fuel injected?

Almost 40. In L.A. traffic, where I can’t ride too fast With the lane-splitting and the open sections and the carpool lanes, I averaged up to 40 mpg. I’ll have to check it again when I just go out riding. (Which I just did, but there are old people and slow speed limits here.) I’ve just assumed it has carburettors. I think the new ones have fuel injection. Mine’s a 2003, so I think it has four Mikunis.
