Hey yall, im new to these bikes and need some help with gas ratio.

For convenience, i would like to carry in my backpack a 6.4oz bottle of 2 stroke oil mix, so when i fill up at a gas station, i can pour in the mix and keep riding.

NOTE:
6.4oz oil mix to 2.5 GALLONS of gasoline = 50:1 ratio

My gas tank only holds 2.5 LITERS of gasoline, and i think 20:1 ratio is what i need for my 2 stroke bike engine?

Problem: how much mix do i pour in my tank when i fill up??

Use 30:1 or more, unless its in break in

You can do a quick google search and find an oil to gas ratio or premix calculator... It really takes a few seconds... no more..

I'm not going to be an as***le, so i'll just say 1.1 to as low as 0.8oz for a liter.
You may have to shake it around a bit in the tank. Dont fill it to the top.

Ok thanks 👍 Now just to be clear, im specifically asking about a 2 stroke oil that creates a 50:1 per 2.5gal gas

Edit: also there is alot of conflicting opinions out there on what ratio to use, which can be quite confusing 🤷

heres the pics

If you want 20:1 use 50 ml/L 125 ml for you 2.5 litre tank. If you want 25:1 use 40 ml/L or 100 ml for your tank.

Mark gave a clear answer above.

The bottle of oil gives the ratio for 2.5 gallons. I was looking for a ratio conversion for my tank which is 2.5 liters.
