Best Synthetic Oil - Buyer's Guide

There are two types of oil i.e.

  1. Conventional Oil
  2. Synthetic Oil

Conventional Oil: It’s a pure crude oil/mineral oils or the by-product of it or derived from crude oil.

Synthetic Oil is petroleum/ crude oil which is chemically treated or went through the chemical process.

The similarity between both oils is that both originate from the ground. You have an option to shift from synthetic oil to conventional oil, or even mix both of them and used but with due precautions and care.

What Is Synthetic Oil?


Typically, synthetic motor oils are known to perform better than conventional fuels, as they refined. The chemical process they go through purifies it, removing impurities from petroleum/crude oil and making all molecules provide a higher level of protection to the modern engines.

However synthetic oil is not recommended if your car is new or if it’s a high mileage car because the engine of the new vehicle is free from wear off initially and you need free-flowing thin oil respectively.

Why Synthetic Oil?

  • Synthetic oils are an incredibly refined lubricant, which offers more excellent protection to the engines of your vehicles and ultimately resulting in better performance and adds life to your engine to the longest possible period. This is one of the most significant advantage this oil offers.
  • Synthetic oils are being made to cater extreme engine conditions,e. stability in high. (when running your vehicle in hot weather conditions, it can cause oil even to evaporate and making your vehicle’s engine catch wear). and low temperatures, i.e. Pour point (an ability of the fuel to move/flow at low temperature), protect against deposits, keeping the engine clean etc.
  • Unlike conventional oil which takes time to in circulating and create friction in the engine, synthetic oil smoothly flows and circulate in the engine during warm-ups of the vehicle without creating any conflict thus lubricating and protecting every part of the engine.
  • With these oils, fuel economy visibly increases as they are not thick like mineral oils and work at a faster pace to make the engine work at its fullest efficiency level.
  • Synthetic oils are also eco-friendly, reduces and making engines to discharge fewer contaminants (reactive, sulfur and unstable hydrocarbons etc.) as compared to unrefined oils.


Some essentials that you should know and consider before buying synthetic oil for your vehicle are:

  • What your vehicle needs: Every car or vehicle’s engines need different oils to make it work appropriately. You must understand the need of your vehicle first to select the best oil for it.
  • Which type of oil is needed: it essential to understand that term ‘Synthetic oil’ is generic, it may be blended or fully synthetic, or it may contain additives (discussed later).
  • How much to invest in synthetic oil: the fact that nobody wants to go for products with a higher price. However it is always good to think long term, investing in cheap synthetic crude may look good for now but to avoid regretting it later and to even saving that amount going total waste, it’s good to spend a little more on a product which will benefit you and your vehicle in the long run.


Viscosity: means the thickness of oil, usually mentioned in the container of oil.

For instance: ’10W – 40’.

(where first number 10 is for viscosity at 0 ° F, W stands for winters and the second number 40 refers to the viscosity at 212 ° F)

Also, consider that oil becomes thin when it’s hot and thick when in high temperature. A proper balance between the thickness and thinness is essential regarding fuel economy and adequate lubrication of engine.


these are commonly added to synthetic oils for the additional benefits like increasing viscosity, adding life to the engine, work as cleaner etc.

Mileage: A good mileage coverage/range is one of the essential factory a good oil offers.
