It is a misconception that engine oil reduces friction between the moving parts of an engine. However, engine oil plays an important role in removing excessive heat from the cylinder liners of the engine. The life of engine oil is measured in kilometres or miles, whichever distance a vehicle has covered. Engine oil needs to be replaced at regular intervals as per the manufacturer guidelines attached to the engine oil. Also, if the vehicle is used in moisture or in a high dirt environment, replacing the engine oil is crucial as dirt and moisture cause damage to the engine.

Tip: While working on the car s engine which is still hot, ensure that there is enough space for movement and the workplace should be organized to minimize the risk of getting in contact with the hot parts of the engine. 2. Open the engine oil drain plug. Torque is to be applied anti clockwise. If the plug seems to be jammed use a long rod to increase the level of torque. Tip: The engine oil drain plug should be removed gently but as fast as possible because the used engine oil will start draining as the plug is removed. 3.

Then close the hood

If the leaks are visible, then slightly, torque the cap and plug wherever required, do not over tighten up the parts. Troubleshooting Engine will not start even though engine oil has been filled.

Crank the engine and keep it running for at least four to five minutes to detect any kind of leaks. 2. If the leaks are visible, then slightly, torque the cap and plug wherever required, do not over tighten up the parts. Troubleshooting Engine will not start even though engine oil has been filled. Less than the prescribed level of the engine oil may lead to such situation. Ensure the level by looking manually, if it is decreased while you have filled in as per the requirements, then check for leaks. Engine oil drain plug s head broke on loosening or tightening.
