Winter doesn't just bring snow and cold weather, it also brings it's own challenges and obstacles that make it harder to improve gas mileage. Outlined here are two things you need to do in winter to promote good fuel economy.

Make sure your oil is the proper grade for winter. As temperatures drop it causes the oil in your car to become thicker. If it gets too thick it will not be able to properly lubricate your engine. Not only will an engine that isn't properly lubricated use more gas but it can also sustain considerable damage. It could even cause damage to the point where the engine would need to be replaced.

Check your owners manual to determine the proper grade of oil for the winter. Generally cold temperatures require a thinner oil then you would use during warm weather. If you are using a multi-grade oil it might work just fine in the winter. Again, check your manual or ask your car dealer what the proper grade for your car is.

Another challenge that winter weather brings is a change in tire pressure. In the winter the tire pressure drops. It is one of the laws of gasses you learned about in chemistry class. A gas compresses as temperature drops. As it compresses, the pressure in your tires drops. If your tires were at the proper pressure at 70 degrees, those same tires will be 5 to 10 pounds too low at 20 degrees and will be 7 to 14 pounds too low at zero degrees.

Low tire pressure is one of the most common gas robbing conditions. It has been estimated that more than 25 per cent of all vehicles on the road have at least one tire with low pressure. You will be decreasing your fuel economy by 4 percent if your tires are 5 to 10 pounds under inflated

Every 10-degree drop in ambient temperature results in a one to two pound reduction in tire pressure. If you set your pressures in November, they'll be too low in February.

To maintain proper tire pressure and avoid losing fuel economy, you need to check your tire pressure at least once every month at a minimum. You should also make sure they are properly inflated when there is an extreme change in temperature.

These are just a few of the fuel robbing conditions that winter brings. You can prevent the decrease in gas mileage and in fact increase fuel economy by knowing about these conditions and taking the necessary steps to avoid them.
