The cost of fuel is a constant frustration for the domestic motorist and professionals in the motorsport industry, and deriving maximum efficiency from fuel makes sense.
A vehicle that is running well will use fuel more effectively, so regular maintenance of any vehicle is important. Ensuring engine parts and fuel lines are free of deposits is important for smooth operation. Effective maintenance also includes making sure that your tyres are inflated to the correct pressure for the type of car and the kind of driving you’ll be doing. Pressure can also be different for front and rear tyres, and correct rotation of tyres will also help ensure the vehicle is balanced. Increased tyre pressure may be required for extremely heavy loads or demanding surfaces.
Driving aggressively also uses more fuel than is necessary. Stop start driving requires more energy than smoothly maintaining a constant speed, so gently accelerating and driving defensively to avoid sudden braking will conserve fuel. Another trick to conserving fuel is to drive at the highest gear possible while staying within the speed limit, and revving the engine as little as possible to reach that speed. The ultimate cruising speed to achieve maximum fuel efficiency will be different for every vehicle, and will be a balance of factors such as wind resistance, the gear being used, and how fast the engine is spinning. Choosing the optimum fuel type for your vehicle could also play a part in how efficiently it performs. Road conditions can also play a role, as driving into a strong wind will need more fuel, as will poorly maintained tarmac. Most vehicles are at their most efficient regarding fuel consumption in the region of 45 to 50 miles per hour.
Quality and performance
Of course, competition driving is all about speed, but the purity and consistent quality of motorsport fuel leads to greater efficiency and consistent performance on the race track. Top grade motorsport fuel is distinguished by its precision formulation and finely tuned balancing of all ingredients.
A warm engine is also a great deal more efficient than a cold one. So the fuel efficiency you will attain at the beginning of a journey could be much less than what you can achieve when all the engine parts are warmed up, well lubricated and operating smoothly. Making one long trip is more effective for saving fuel than a series of short trips. Planning to combine a number of trips in one will save fuel.
Generally being organised and putting some thought into your motoring will help with conserving fuel. A well maintained car travelling on tyres inflated at the correct level, sensibly planned journeys and driving with the aim of decreasing and increasing speed smoothly will all increase fuel efficiency. Remaining at the same speed in the highest gear when possible will also contribute to saving fuel and money.
