i have a couple of 80's 2-stroke go karts and they run on Shell Advance R castor oil other than that have never heard of it being used for anything. Thanks for the advise, i will go with the 50:1 semi synthetic and see from there.
Thanks again.

The guy i got it from said to run it at 25:1 which would mean 200ml of oil to 5 litres petrol which to me seems very rich, he also told me to run it on castor based mineral oil i take it he didnt have a clue??
Hello,
