Fuel consumption

[Sam410]

According to my app, my 410 has averaged 16.7 mpg (calculated tank by tank) over the last 35,000 miles. High is around 22mpg, achievable if I sit at a steady 70-80mph on the motorway for the whole tank. (I have sometimes filled up from empty three times in a day if travelling long distances.) Low was 7.7 mpg, achieved by filling up in east London one Friday afternoon and after taking well over two hours to get across town I filled up again in west London, just out of interest to see how low the mpg could go.

The overall average reflects quite a lot of short journeys, as I frequently use the car locally, but also my lead footed driving style. The engine is the 318, but was slightly overbored in a 1990s rebuild, and I think it has a slightly hotter camshaft than standard. Gearbox is standard 3-speed.
