Convert miles per gallon to litres per kilometre how to#

Relative to the optimal speed of 55 MPH, on average, a vehicle is: According to the Department of Energy, maintaining constant speeds using cruise control helps reduce unnecessary acceleration and deceleration, which improves fuel efficiency. Use cruise control when possible, such as on long, straight, and rural highways. Department of Energy, the optimal speed for fuel efficiency is 55 MPH, but this may vary depending on the given vehicle. When allowed by speed limits, 55 MPH (90 km/h) is best for gas vehicles–According to studies by the U.S.Also, ensure that wheels are properly aligned. It is best to consult the driver's manual (also usually available online) or the side markings of the tires to find the optimal PSI range. Rigidity in tires allows for greater frictional interaction between rubber and the road, imparting forward momentum. Tires–Under-inflated tires can lower gas mileage by 0.3% per PSI drop due to wasteful transfer of energy dissipating into the mushiness of the tires when they are underinflated.By powering all four wheels, the engine works harder to move a car the same speed at higher speeds. Overall, 4-wheel drive vehicles tend to be less fuel efficient than FWD or RWD. Drive a fuel-efficient vehicle–Please visit /feg/bestworst.shtml for the fuel efficiency comparison between different vehicles.
