You just buy regular unleaded gas and mix it with the oil that you can buy at any convenience or hardware store, such as, Walmart, Dollar General, etc.
You'll use just good old two-stroke oil of any kind and will want a mixture of anywhere from 32:1 to 50:1.
make SURE it is 2 STROKE OIL its either red or a bluish color DO NOT mix with motor oil.
oh and most importantly, when u get it started.......if its ur first start.....go easy. NO FULL THROTTLE untill at LEAST 3 or 4 tanks of 50-1 mix.
oh yea and most of all.....
