Introduction
Fuel powers your vehicle, but lubricants play a different and equally important role in vehicle maintenance.
Engine oil helps reduce friction between moving components, supports heat management and helps protect engine parts against wear. Selecting the correct lubricant and changing it at the recommended interval are important parts of vehicle care. Here is what every motorist should know.
What Does Engine Oil Do?
An engine contains numerous moving parts that operate under heat, pressure and friction.
Engine oil creates a lubricating film between appropriate surfaces, helping reduce wear. Depending on its formulation and the engine design, it also helps manage contaminants and supports cooling and corrosion protection.
Over time, engine oil degrades and may become contaminated. That is why regular inspection and timely replacement matter.
Why Does the Correct Oil Grade Matter?
Engine oils are available in different viscosity grades and specifications.
Viscosity describes how easily a fluid flows under particular conditions. Manufacturers specify suitable oil grades and performance requirements based on engine design and operating conditions.
Using an unsuitable oil may compromise the intended lubrication and protection. Before purchasing engine oil, consult the owner’s manual or an authorised service professional. Do not select a lubricant based only on its price or viscosity number.
What About Synthetic and Mineral Oils?
Broadly, engine oils may be formulated using mineral base oils, synthetic base oils or blends.
Different formulations can offer different performance characteristics. However, the most expensive or most highly marketed oil is not automatically the right choice for every engine. The manufacturer’s specification should guide your decision.
How Often Should You Change Engine Oil?
There is no single oil-change interval that applies to every vehicle.
The recommended interval depends on factors such as the engine, oil specification, mileage, age and driving conditions. Follow the maintenance schedule in your owner’s manual. If you frequently drive in demanding traffic conditions or your vehicle has a specific service requirement, consult a qualified technician about the appropriate interval.
Signs That Your Vehicle Needs Attention
Pay attention to: • An engine oil warning light. • Oil levels below the recommended range. • Unusual engine noises. • Visible oil leaks. • Unexpected changes in engine performance.
An oil warning light may indicate a serious problem. Stop safely and follow the vehicle manufacturer’s instructions rather than continuing to drive without checking the issue.
Are Lubricants Different From Fuel Additives?
Yes. Engine oil is primarily used to lubricate and protect appropriate engine components. Fuel additives are different products designed for specific purposes, depending on their formulation.
Never pour a lubricant into the fuel tank unless a product is specifically intended and approved for that use.
Choose Lubricants Carefully
IndianOil offers the SERVO range of automotive lubricants. Availability of individual products may vary by station.
Bowring Service Station, located on St. Mark’s Road, Bengaluru, lists SERVO lubricants among its offerings. Customers should confirm the availability and compatibility of a specific lubricant before purchase. The right lubricant, timely maintenance and professional advice can help you care for your vehicle throughout its service life.
