Engine Oil Knowledge

What is the function of Engine Oil ?

The principal function of the engine oil lubricant is to extend the life of automotive that operates under different conditions like speed, temperature and pressure.

Sufficient lubricant in automotives reduces friction and removes heat from the engine. At low temperature to maintain the performance of the engine, where at higher temperature to keep the engine apart to minimize engine wear. Regular oil changes have a variety of benefits: they should give your vehicle a longer life, make you engine run smoother, improve your MPG and reduce emissions. So, in the long run this should mean more money in your pocket as your car's day to day functioning is improved and its life time is extended. It may not affect your car insurance rates, but it should cut the cost of servicing and maintenance. So, just by using sufficient engine oil you should make your car healthier and happier.

How to read engine oil label ?


API Service Symbol
The API (American Petroleum Institute) shows you the performance level.
The first letter indicates the vehicle fuel type that the oil is designed for.
"S" (Service) is intended for Gasoline engines. "C" (Commercial) is for Diesel engines. The second letter designates the quality level of the engine oil. The higher the letter, the more advanced the oil. Refer to Engine Oil Guide.

The SAE (Society of Automotive Engineer) Viscosity Grade, it is define as the measure of oil’s thickness and ability to flow at certain temperatures.

Total Base Number (TBN)

The total base number (TBN) indicates its acid-neutralizing ability and is expressed as mg KOH/g of additive.

TBN determines how effective the control of acids formed will be during the combustion process. The higher the TBN, the more effective it is in suspending wear-causing contaminants and reducing the corrosive effects of acids over an extended period of time.
