Maths not being my strong point, I've been looking at those fancy pre-mix containers like the Accu-Mix. Problem being that the Accu-Mix apparently only goes to 50:1 when the Montesa manual states 80:1 (or maybe 70:1). Has anyone got round this problem or bought a similar product?

Hey If you look at this chert it tells you how much oil to add to a gallon (5 litres) of petrol

Hope this helps

Oooh, thanks Sean and thanks John Hird, whoever you are

I stumbled across this very trick little calculator for mixtures HERE

Great chert Barrybaines.If your mix is 80:1 you can buy a 10Litre can put in the 8 Litres add 100 millilitres of oil or 1/2 the amounts if you haven't enough room in the can.

Just use the 40:1 amount and add it to two gallons instead of one.
