v1nn1e Posted April 27, 2018 Report Share Posted April 27, 2018 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 Quote Link to comment Share on other sites More sharing options...

carl ekblom Posted April 28, 2018 Report Share Posted April 28, 2018 (edited) 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%. /Carl Edited April 28, 2018 by carl ekblom Quote Link to comment Share on other sites More sharing options...
