To help prevent vapour-lock in the hot weather, Joan has advised that I mix 50/50 unleaded and 4 star petrol on the hot days and 100% 4 star on very hot days. At that price I will not be flying on very hot days!
Still I bought 40 litres of 4 star, which at 50/50 and 10 litres an hour will last me a month or so. I reckon I might need one more batch before the cooler days arrive.
Hoping to go to Rougham Wings, Wheels & Steam fly-in this weekend.
