Car Engine Oil Buying Guide in India with Synthetic Vs Mineral Oil Differences Explained

Car Engine Oil Buying Guide on Viscosity Grade, Differences in between Synthetic Oil and Mineral Oil with Best Brands and Prices among Castrol, Mobil One and Shell Helix Brands

 

Car Engine Oil Guide

Engine Oil is the most important component for Lubrication of Car Engine along with protecting wear and tear of engine parts and prevent corrosion. Thus, is utmost important to choose in right grade and timely replacement for Optimal Performance of your car

Shelix, Castrol, Mobil One are well known names and are endorsed by several manufacturers in India and worldwide as recommended brands for refilling Car Engine Oil. Below are prices and range from these companies

Before Choosing Engine Oil - its recommended to check your Car Owner Service Manual for

» For API standard such as API SL, SM, SN or SJ - API Standard basically is benchmark set by American Petroleum Institute about performance and power of Engine Oil. Its recommended to check your Service Manual for API Standard recommended for your Car Engine Oil

» Viscosity grade - Viscosity Grade is basically the thickness been defined for Engine Oil and defines the stress holding capacity. A thin Engine Oil may well be recommended for Winters, while Engine Oil with higher Viscosity is recommended for Summers Environment. For example - Water has lowest Viscosity as its the thinnest.

Viscosity Grade comes in 2 numbers :- Like 10W-30, 0W-40 or 15W-40 or 5W-30 . To make it simple to understand - a lower Viscosity means Oil is thinner. When Oil reaches full temperature - the weight is thus determined which is 30 or 40.

» ACEA Rating - The Lubricant Properties are determined in ACEA Rating and one can find ACEA rating as A3/B4, A5/B5, C2 etc. The properties are determined basis Wear, Sludge, Soot Thickening, Oxidative thickening, Fuel Economy and lot other factors to determine the best oil type for your car

 

Decoding Engine Oil Grade

Correct Engine Oil Grade is utmost important as it determines the free flow of Oil to several Components. Incorrect Viscosity grade can lead to premature wear and tear of several small engine parts.

First Part Winter Grade (0W, 5W, 10W etc.)

5W-30 - Here W is Winter Grade. 5W is Viscosity Grade of Cold Start

0W- 40 indicates that Vehicle can start easily in even Coldest or Freezing Conditions. The Oil is relative thin enough to free flow across all components

10W-30 - it would have implied 10W for conditions where temperature remains a bit higher. The Oil is relative thick

Low Winter (W) viscosity lets Oil flows in Engine in colder conditions much quickly with lesser dry running. Less dry running means much less engine wear.

Second Part Temperature Grade (20, 30, 40)

5W-30 - Here 30 determines the thickness of Oil at Engine Temperature of 100 Degree C. Its best to follow the recommendation as per Owner Manual on thickness on maximum operating temperature. 30c is a thin Oil than 40 in maximum operating temperature of Engine

0W- 40 indicates the thickness of Oil on maximum Operating Temperature. 40 means that oil turns relative thick against the scenario of 5W-30

 

Type of Engine Oils with Prices

There are 3 Types of Engine Oil available - Synthetic, Semi Synthetic and Mineral Oil. Difference in Performance is :-

» Synthetic oil : Here the Molecular property of Oil is engineered to give best protection to car from regular braking, clutch, acceleration - i.e if you commute daily and faces traffic will produce lesser sludge and wear and tear to Engine. Its the best Suited Performance Oil for Cars and can even lead to slight mileage improvement too.

Due to Oil Molecular property been developed and arranged - this Oil leads to lower NVH Levels and best suited for those who drive long distance, drive in heavy traffic, start-stop drive or in Diesel Engines looking for best performance along with optimal protection

Synthetic Oil Cost in around Rs 1050 to 1250 per Litre

» Semi Synthetic Oil (costs much less) can be used in cars, as cost effective solution. Especially, where one your annual running is not more than 10,000 Kms.  Semi Synthetic Oil costs in range of Rs 550 to 650 per Litr

» Mineral Oil - Cost Effective solution for cars with smaller engine and less driven. Mineral Oil is priced just 1/3rd against Synthetic Oil . To our view - It may be used, if looking for cost effective solution for cars, with less driven (under 500 Kms a month) or not to commute in daily bumper to bumper traffic.

Mineral Oil Costs in range of Rs 300 to 350 per Litre

General capacity on most of Hatch, Compact Sedan, Mid Sedan and Mid SUV is in range of 2.9 Litre to 4.6 Litre Engine Oil.

Replacement Cycle of Engine Oil: Though - for changing Engine Oil - its best to again refer to Owner Manual. But - for a common understanding (as extracted through Engine Oil Makers) - it can just prove to be ideal to replace Oil as below:-

» Mineral Oil in after 5000 Kms or 6 Months of Usage.

» Semi Synthetic in 5000 to 7500 Kms or 12 Months

» Synthetic Grade lasts ideal if annual running mileage is from 10000 to 15000 Kms or 12 Months.

Synthetic Oil Grade offers best life to Engine, Prevent Sludge from Daily Traffic Drive with Lowest Noise Levels and Optimal Performance for Mileage and Pickup. Using any Grade beyond its Life will tend to break in Viscosity Molecules and may enhance friction to Engine Components for quicker wear & tear along with deterioration in Performance.

 

Should you Replace Engine Oil if driving Car for Less Kms

For some who drive less like 2500 Kms or say 5000 Kms a year, while the Owner Manual mention replacement as 10000 Kms or a year - its also important to replace Engine Oil on time as  the bare basic. Engine Oil is made up of Viscosity Molecules.

When Oil is poured in Engine - with usage and time shelf as suggested - there is a high probability that Molecules tends to breakup over period of time and oil tends to be thinner beyond its shelf life (and if continued) leads to friction of engine components with faster wear & tear

Ideally Engine Oil change is best when followed in Manufacturer Schedule which is based on

> Kms Driven

> Time Factor

as whichever earlier. 

 

Engine Oil Grades (Best Oil basis Indian Driving Conditions)

In terms of Oil Grade

» 0W40 / 0W20: Is considered the Most Superior Engine Oil Grade in Indian Market. It Performs well and efficiently in both Hot and Cold Climate with Least Sludge and Top Notch Efficiency. 0W40 Grade is Ideal for Modern Engines in Both Petrol, Diesel or on CNG Driven Cars - unless specifically referred in Owner Manual

» 5W40 : Ideal for Diesel Cars - Available in Semi Synthetic to Synthetic Grade. The Oil Performs Equally Good as what 0W40 - except in extreme cold Situations. Prevent Sludge and Provides Optimum Performance

» 5W30 or 10W30 : For Modern Petrol Engines - looking for Mineral or Semi Synthetic Oil - yet Light and Optimum Engine Performance. Cost Effectiveness and Low Viscosity makes Oil Performing Well on Modern Age Petrol Cars with Good Fuel Efficiency.

» 10W40 : Available in Mineral or Semi Synthetic - Ideal for Diesel Engines and where Climate is not much Colder. Works extremely well in Summers and considering Indian Climate - where barely temperature goes to Minus Degree in Plain region - its an Affordable yet Effective Grade for Diesel Oil

» 15W40 or 20W50 : For Older Age Cars - wherein recommended Grade is 15W40 - however this Oil is thicker and is barely recommended in any Modern Age Cars having Superior Engines.
