Tips for Diesel Car Drivers
This type of car is by far the smartest choice for everyday motoring, and as the majority of diesel cars have a Fuel Cut Off valve, which cuts off the fuel supply when you take your foot off the pedal. In the grand scheme of things, it does a similar job to the EFI setup in a petrol car. Although the Fuel Cut off Valve in a diesel, is entirely different to the EFI setup in a petrol car, they both cut off the fuel supply when you let off the throttle, so the same driving style applies. For this reason I recommend all the same tips described for a petrol manual car. The bonus with a diesel engined car, is a lot more engine torque/pulling power, this enables you to change gear earlier, and cruise at much lower revs. Diesels engines are also much more efficient at tickover, than petrol engines, and as far as driving techniques are concerned, I’ve more or less covered it in the Petrol/manual section.
