Engine Here are few tips that can increase the engines life: -

• Make sure that you change the PCV valve annually. Change the air filter after every 15,000-20,000 miles and the antifreeze after every 2-3 years. Always use a good motor oil, this is very essential to increase engines life
• Running an engine while under power and with high temperatures can be harmful. Make sure that there is an optimal coolant temperature, somewhere between 160' and 210'. Excessive temperature may harm your engine. Avoid higher oil temperatures as it can break down your motor oil. Moreover, it can also be a cause for the metal parts coming into contact with each other.
• One of the best ways to increase engines life is to maintain less compression. Also, proper ignition timing is important. Little timing can lead to exhaust valves turning red-hot and excessive timing may lead to pre-ignition, which can hit the piston with the sledge hammer. If an exhaust gets too hot, the engine head may eventually crack or get destroyed. To increase engines life, it is important to know the right timing.
• Always go for optimum oil level. Too much oil can lead to the rods and crank whipping it up and adding air, and that's not a good sign at all.
• Proper Start-up is very important to increase the life of the engine. You should not start your car when its completely cold, instead give the engine the sufficient time to warm up. Allow the car to warm up to operating temperature until the needle on the gauge is midway, this will probably make your car's engine last longer. Do not start your car unless and until the engine is warm.
• Proper Clearances are important. Lash, piston to wall clearance, main bearing clearance, rod bearing clearance, etc., all are extremely important.
• Time-to-time check-up of the engine is important in order to find out any leakage. Engines should be checked periodically in order to increase its durability.
