There is a LHS in Adams and I will find a ride to get there, but he contradicts what others here say.
When I bought some fuel from him he told me that 15% fuel is best for all trainers, that is why I asked here what fuel was best.
And the answer here is no more than 10% nitro.

I have not seen an engine run on the fuel I bought from him last year as that fuel is now with someone else. But if I go to him to buy the fuel he will again tell me 15%. I want to take the advice given here so I see it as being easier buying it online.
