Bro, its just an octane booster. you can also get similar results by using high octane fuel in your bike. infact, from what I have read, Suzuki GS-150 is built with compression ratio of 9.2 to 9.5:1 which is in the vicinity of 90-96 RON. That means, you don't really need high octane fuel in it. you may get better pick, acceleration and fuel economy but the added cost of fuel will outweigh the benefits.
just mix one liter of ethanol based petrol with a full tank of regular petrol and you'll get similar results, assuming that your bike's tank can hold 12 liters in total. you can get E-10 petrol from PSO station in Constitution Avenue Islamabad. Ethanol has a tendency to eat away fuel lines. if you are concerned about it, then just use two liters of high octane fuel with a full tank of regular petrol.
