You will also find that alcohol blends dissolve practically all the dirt and sediment in the fuel system and wash it through to the carburettor. This may be alright on a new car, but in a car which has been in use for some time, you may suffer considerable inconvenience due to accumulated deposits of various sorts being dissolved into the fuel system. Finally, I would say that, from the point of view of your work's tests it might be quite safe to use Koolmotor Alcohol blend as supplied to yourselves, but I should be very careful regarding the supplies you pick up from the ordinary road-side pump. I hope to come up and see you after Whitsun, but I have been abroad fairly continuously during the last month or so and it has been impossible to make a definite appointment. Will you be working immediately after Whit Monday? Kindest regards, Yours sincerely, H C Banks P.S. If you like to send us a sample of Koolmotor Alcohol blend I'll do a test on it. HCB | ||
