I own a 2nd hand 2001 honda dio. 50cc's of pure scooter muscle.
I live very close to the middle of town and scooter to uni through the intense traffic every day.
I spend NZ$10 on gas every 2 weeks and save hours by being able to scooter between traffic
a gallon of veggie oil (clean, from the grocery store) is still cheaper than gas. if you were REALLY that lazy that you dont want to go around to restaurants to get the oil and filter it then you can still dump just straight clean veggie oil in.
