A .3 Four Stroke model Car engine ?? It must be complex and expensive. Does it use regular valve springs ??
An eye dropper for an oil change?
Fuel injection or carb? A 4 barrel and dual turbochargers would really make it go !!
One a more serious vein, VW now has an experimental absolute economy vehicle employing a single cylinder 4 stroke Diesel (what else?), pushing out all of 8.5 hp. It can cruise at 60 - you may want to know the MPG, or the more up to date, l/km,(Liters per kilometer) (European)..
