Well I have just "gone for it" after getting nowhere and so much mis-information everywhere
Initially had a mix of around 37% SVO to 63% diesel no probs so on next fill up i put a 50/50 mix in right upto the brim (76 litres) done around 250 miles so far in it but have noticed its more difficult to start

other than that seems ok, bit dis-concerting about starting as the current ambient air temp must be 15-20c, so I guess it would be much worse in the winter, heard a cap full of thinner may help this issue although not tried that yet, also pre heater is an option but as yet I dont know how difficult or how much this is likely to cost
Viva la revolution
