An Introduction to the Segment of Automotive Oil via Viscosity

Press release   •   Dec 03, 2011 16:21 IST

Though the automobile industry is promoted as a speed oriented domain, it has always been a performance oriented one; after all, speed is just one of the facets of an automobile. Now, considering all the facets of the automobile sector and its capacity, one of the main aspects holding ground in the race of performance is oil, or rather different types of oils having many different functions. Zeroing in to the core, the one thing which would be the difference between running of your automobile and running it excellently is: the right automotive oil.

Choosing the right automotive oil is nothing but fitting perfectly into the cavity called manufacturer’s specifications. This would not only help you to maintain the coverage of warranty (indirectly) but would help you get the best deal (smoother operation) from your automobile. Automotive oil is a part of the ‘oil engineering’ or ‘liquid engineering’ segment and over the years, this segment has advanced to match the aggressive requirements of engines.

Prior to that, users need to understand the basic type of classification in this segment, mentioned as follows:

  • Straight oil

  • Multi viscosity oil

  • Synthetic oil

The part of differentiation in the above classification bows down to the viscosity aspect. Viscosity is the property that eases the flow of a liquid, or in other words, it is the thickness of any fluid. Hence, higher the viscosity, thicker is the liquid (commercially available Vaseline is thicker than oil, water etc). Viscosity of any type of oil gets adversely affected by alterations in temperature, both the decrease of it and the increase as well.

Talking about automotive oil, a rise in temperature reduces its viscosity which puts the engine vulnerable to friction. The other side that is decrease in temperature is also quite catastrophic to the engine. Straight (often dubbed as first generation or direct) oil caters to the high temperature end but fails to cater to the low temperature zone (during winters). Here, the second type, multi viscosity oil or second generation oil pitches in. Like the name suggests, this automotive oil caters to both ends of the temperature spectrum (high and freezing temperatures).

But, this multi viscosity oil doesn’t carry the same properties over a period of time, hence there is a need of a type of oil which not only works effectively, but works over a period of time as well; this gap is filled correctly by synthetic oil or the third generation oil which not only performs the standard function but reduces wear of the engine components. The cost factor increases in the ascending order from straight oil towards synthetic oil.

Lastly, apart from the owner’s manual and viscosity aspects, the other aspects that hold ground towards finding the right automotive oil for your automobile are as follows:

  • Users living in cold temperatures would prefer lower W rating (10W-40: here, 10 is the index and W stands for winter).

  • Post performance zeroing-in also works with good monitoring of the engine.
