Puzzle 5

During a recent trip to Scotland, I filled my car's 10 gallon fuel tank to the very top.

I travelled at 60 mph up the motorway, and I knew that I averaged exactly 40 miles per gallon.

However, the moment I started, my fuel tank developed a leak, and four hours later I came to a complete stop as I'd run out of fuel!

How much fuel did I lose through the leak?
