Have tried 10% kerosene in petrol in a 1926 Vauxhall - it gave it a slightly higher top speed in tests - would expect it to be fine in a Seven. I believe that the adding 10% is allowed in the UK, but it wasn't really worth it from the power point of view. As to helping vapour lock - not sure about that - would be interested to hear if it does make a difference. Not that I have a vapourisation problem in Cheshire - as yet.
