You can save 3% fuel with a new spark plug. Confirm that the spark plug model is correct and the du ignition gap is appropriate. Check the spark plug wire for cracks or burning, and check the insulation for damage. A broken high-voltage line will increase fuel consumption because it cannot conduct enough voltage to the spark plug. Make sure to adjust the ignition timing according to the instructions. If the electronic ignition system is not used in the car, it is necessary to check and maintain the contacts, ignition head and distributor cover of the distributor according to the instructions.

2. Replace the air filter regularly.

A dirty air filter will thicken the air-gasoline mixture and increase the fuel consumption by 10%. Replace the gasoline filter at the time required in the instructions. Ensure that the mixture of idle speed and carburetor is properly adjusted according to the instructions. Use oil with specified viscosity to reduce friction. Use rear axle and transmission oil with specified viscosity. broadsword

3. Repair the cooling system on time

Check whether the water tank cover is cracked or damaged. If the water tank cover is not tightly closed, the cooling system will not work properly. Verify that the thermostat is working properly. If the thermostat is slow and does not open for a long time, it will also delay the engine heating, and the fuel consumption of a cold engine is twice that of a warm engine.

4. Confirm that the tire pressure is normal.

Insufficient tire inflation will increase fuel consumption. When inflating, a little more pressure can save fuel, but it can't exceed the maximum pressure of the sidewall standard. Make sure the drive belt is normal (especially the fan belt) and adjust it properly. Make sure the battery is fully charged and easy to start. Make sure all tires are properly balanced. Make sure the front wheels are correct and accurate.
