Measures to be taken to conserve oil are: 

1. Walk, ride a bike, carpool and use public transportation whenever possible. 

2. Prefer public transport system like bus or train instead of travelling in personal vehicles. 

3. Choose materials other than plastic which uses crude oil for household items. 

4. Use cloth or paper bags instead of plastic bags when shopping. 

5. Use organic fertilizers for agriculture and gardening because fossil fuels are used in making chemical fertilizers. 

6. Produce renewable biofuels to power cars and trucks. 

7. Vehicle owners should keep their vehicles serviced i.e., correct amount of air in fires, oil change, spark plug/fuel injector checks, often-at least quarterly. 

8. Drive in the correct gear. Incorrect gear shifting can lead to as much as 20% increase in fuel consumption. 

9. Consider a hybrid vehicle or an electric vehicle.

If we do not conserve oil, we never get oil after 46-47 years. So all the industries that depend on the oil for energy will break down. Facilities linked with oil will be hampered. So the future generations will suffer.
