re: Power out put (carburation) from Bentley engines.
----------------------------------------------------

"Sr" has requested we to drop you a personal line as to the best petrol or mixture of petrol to use in order to obtain maximum power when giving special trials to customers where there is the possibility of competition from other makes of cars such as Alfa-Roméo, Bugatti etc..

We, at present, use Esso petrol.
