Hey everyone.

I was doing some surfing about fuel consumption, and came across Transoprt Canada website. Here is some info about fuel mileage.

Factors That Affect On-Road Fuel Consumption

Temperature

At 0°C, fuel consumption is increased about 8 percent while at -30°C, consumption is increased by an average 30 percent.
Terrain and road

Twisting roads in rocky terrain may cause repeated speed up/slow down acceleration which increases fuel consumption.

Driving in snow increases fuel consumption because snow increases wheel slippage and resistance to vehicle motion.

Rough asphalt, pot-holes and gravel-surfaced roads can increase fuel consumption up to 35 percent.

Vehicle load and condition

Some vehicle options such as air conditioning or a loaded roof rack may be taken into account during the laboratory tests but their effect on fuel consumption can only be estimated. Additional options which add weight to a vehicle (e.g. four-wheel drive) also increase the load on the vehicle engine, increasing fuel consumption. The same holds true for extra passengers and additional weight carried or towed.

Proper vehicle maintenance helps to ensure proper fuel consumption. Low tire pressure, incorrect wheel alignment, brake drag all contribute to increased fuel consumption.

Driving style

Short trips of 10-15 minutes without engine warm-up cause high fuel consumption because the engine does not remain at its operating temperature for any significant length of time.

Quick accelerations, fast stops and excessive speed also result in higher fuel consumption for the vehicle.

They had links to other websites including U.S. government sites.
