How Britain compensated for limited domestic oil

How could Britain support an oil-fuelled fleet without large indigenous oil supplies?

It lined up multiple external sources, including Canada and the Middle East, rather than relying on domestic production.

Britain did not possess the indigenous oil supply implied by its fleet's needs. Canada and the Middle East provided external sources instead. Planners had arranged more than one supply route. Domestic resource ownership and a diversified fuel supply were therefore separate questions.
