Just thought I'd clarify a few of the common petroil mixtures - do please someone check my maths!

Ratio             Percent               Oil/Petrol

80:1                1.25%                12.5ml/litre

66:1                1.5%                  15ml/litre

60:1                ~1.7%                17ml/litre

50:1                2%                     20ml/litre

Just use one of the many pre mix calculators on the web like the one above......

v1nn1e:  Your calculation is correct 

1.5% is what I use for trials two strokes or 75ml/5 litre

Or Aspen 2-stroke petrol which is 2%.
