If I am not wrong, there is a minimum fuel requirement, eg
95-Unleaded. Prices range differently from different petrol kiosk.
If u see carefully, the petrol kiosk has different numbers, eg 92,
95, 98, the smallest no means the cheapest. They simply mean the
percentage of octane in the petrol.
My bf's SP can pump RM18.00 (@ RM1.58/litre) from almost empty
tank, and his mileage is around 220-240km for full tank. The fuel
consumption differs from bike to bike. So don't expect 2 same bikes
to have the exactly same fuel consumption. It all depends on your
riding style and engine condition and types of 2T oil u use.
