Millions of dollars worth of gasoline is wasted every day by motorists, because simple and inexpensive vehicle maintenance is neglected.
Fuel Savings Maintenance Tips
- Check vehicle gas caps - About 17 percent of the vehicles on the roads have gas caps that are either damaged, loose or are missing altogether, causing 147 million gallons of gas to vaporize every year.
- Make sure tires are properly inflated(do not over pressure the recommended pressure use the recommended pressure as in car manual - When tires aren't inflated properly, it's like driving with the parking brake on and can cost a mile or two per gallon.
- Replace spark plugs regularly (Recommended every 5000km~8000km as max)- A vehicle can have either four, six or eight spark plugs, which fire as many as 3 million times every 1,000 miles. That results in a lot of heat and electrical and chemical erosion. A dirty spark plug plus causes misfiring, which wastes fuel. Spark plugs need to be replaced regularly.
- Replace dirty air filters - An air filter that is clogged with dirt, dust and bugs chokes off the air and creates a "rich" mixture - too much gas being burned for the amount of air, which wastes gas and causes the engine to lose power. Replacing a clogged air filter can improve gas mileage by as much as 10 percent.
Fuel Saving Driving Tips
- Don't be an aggressive driver - Aggressive driving can lower gas mileage by as much as 33 percent on the highway and 5 percent on city streets.
- Avoid excessive idling - Sitting idle gets zero miles per gallon. Letting the vehicle warm up for one to two minutes is sufficient.
- Observe the speed limit - Gas mileage decreases rapidly at speeds above 60 mph. Each mile driven over 60 will result in an additional 10 to 20 percents oil loss per gallon. To maintain a constant speed on the highway, cruise control is recommended.
