There are as many opinions on what to put in the gear box as there are riders... Either will work fine. Just change it often

Bit of maths comes in for this. You want 40:1 fuel/oil ratio right? Say you've got a 5 Litre gas can, change that 5 Litres into Millilitres > 5000ml

Now, divide that 5000ml into 40 > 125ml

So, you need to mix up 125ml of oil to every 5000ml (5 Litres) of fuel

Measure it out in a jug, add some fuel to this oil, whisk it up for a minute, add this to your gas can with the rest of the fuel in it, give it a good shake for another minute and whack it in your fuel tank. Done.

K..so if u got a full quart of oil,u add to the 16 mark to 5 gallons for 40-1.
Yes, 16 ounces into 5 gallons will give the 40:1 ratio. Alot people just buy a pint bottle and just dump the whole thing into a 5 gallon jug, so there is no measuring required.

The best way to do it is with the RatioRite cup...

Find the ratio you want to mix, fill to that line and mix.. Simple, no guess work.
