How To Choose The Best Synthetic Motor Oil For Your Car

Synthetic motor oil is designed to maximize the motor’s lifespan by decreasing the wear and tear of its internal parts. Synthetic motor oil is a lubricant that can reduce the friction between the motor parts. The properties of synthetic motor oil could be increased by using specific additives, which has led to a diverse market. Selecting the best product from this diverse market is a complicated task if you are a beginner and if you do not have any up hand knowledge on synthetic oils. However, if you consider the factors mentioned below, you would be able to pick the best synthetic oils with ease.

  • Type of synthetic oil

One of the most important things about synthetic oil is that they are available in two different types, synthetic blended motor oil, and full synthetic motor oil. Therefore, before purchasing synthetic oil, the first thing you should consider is if the oil suits your motor. Not all cars come with an engine that is designed to function on full synthetic oil, you should know that full synthetic oil is tailor-made to deliver specific benefits. Full synthetic oil is designed to offer high efficiency and is comparatively expensive than synthetic blended motor oil. On the other hand, synthetic blended oil comes with the properties of both synthetic oil and standard engine oil, as the oil itself is a mixture of synthetic and standard oil. If compared to full synthetic oil, synthetic blended motor oil is cheap and a good alternative to full synthetic oil.

  • Viscosity grade

When it comes to motor/engine oil, viscosity is one of the most important factors to consider. Let it be standard engine oil or synthetic oil, you cannot neglect considering the viscosity. Why is the viscosity of motor or engine oil very important? The answer is simple, as the viscosity of the motor oil changes, the overall property of the oil changes. Now, here is how to select suitable viscosity synthetic oil based on the temperature of the engine.

  • High engine stress and high temperature 

There are several circumstances where your engine will be stressed; this includes harsh driving, long drives, racing, climbing uphill, towing, etc. If the engine is under high stress, it will obviously produce more heat, so the temperature will be high. The engine oil should be thicker or else the oil would burn and kill the engine at such engine conditions. Different synthetic oil comes with different viscosity and here you will need synthetic oil with a 10W-40 viscosity. Using any other synthetic oil will reduce your engine lifespan and gradually kill your engine.

  • Medium stress and medium temperature 

An automobile engine will be under medium stress while traveling on a paved road or in cities. While there is medium or typical stress on the engine, the heat and temperature produced by the engine is medium or typical. For such engines, synthetic motor oil with a 5W-30 viscosity is the best. If you are a daily commuter, then, 5W-30 viscosity synthetic oil is the best recommended for you.

  • Cold weather 

Do you live at a place where the surrounding temperature is comparatively low? Do you find it difficult to start your car because the temperature is too low? If yes, it is very important that you consider purchasing synthetic oil designed specifically for such conditions. It is best recommended that you go for 0W-30 viscosity synthetic motor oil, as oil with this viscosity can tolerate low temperature and it can help the engine function smoothly.

It is very important that you read the above-mentioned facts and consider purchasing synthetic motor oil with adequate viscosity. Remember, synthetic oil with right viscosity can keep your engine safe and increase its lifespan. On the other hand, if you end up choosing the wrong viscosity, then it could do harm and waste of money.

  • Additives 

As already mentioned above synthetic motor oil is tailor-made to deliver a specific set of benefits to the engine/motor; the additives in the oil will decide what the oil could do. This is why it is very important to know about additives and the common types of additives added.

  • Viscosity-index improvers – This additive is added to synthetic oil as it plays an important role in reducing the thinning character of oil at high temperatures. If you are purchasing synthetic motor oil for a high-stress engine, then this additive is very important.
  • Detergent – It is a well-known fact that detergents are something that does cleaning better. When it comes to engine/motor oil, detergent additives serve the purpose of removing debris in the engine. In other words, detergents help oil to deliver a better cleaning job.
  • Antioxidants – As the name itself suggests, antioxidants prevent oxidization. When it comes to oil, antioxidant additives can prevent the base oil from decaying due to oxidization.
  • Anti-foam agents – Foaming is one of the common results of fast-moving parts when it comes to oil, foaming can lead to oil losing several properties, this is why it is important to prevent foaming.
  • Conditioners – If your motor/engine is old and if you think the engine already has some wear and tear, then your synthetic oil should have conditioner additive. This additive will help the old and loose seals swell and prevent any oil leaks.
  • Dispersants – The basic purpose of this additive is to prevent the debris and particles in the engine to stick together to form a sludge or block.
  • Zinc dialkyldithiophosphate (ZDDP) – The exact functioning and purpose of this additive is still unknown, however, some of the experts have reviewed this additive to deliver an anti-wear property as it reduces the wear and tears inside the engine.

The above-mentioned are few of the common additives used in synthetic oil, now; you know the purpose each additive, based on this knowledge, purchase suitable synthetic oil.

  • Brand 

As already mentioned several times above, the motor oil market is diverse and so is the synthetic motor oil market. Check the market and you will find more than a dozen different top brands competing for market dominance. However, when it comes to synthetic oil, we would like to recommend that you consider the brand only after you have considered the type of synthetic oil, viscosity, and type of additives included. And while purchasing synthetic oil, it is very important that you consider purchasing it from a top-rated brand and not a generic brand.

  • Price

Synthetic motor oil is comparatively expensive than standard engine oil. At the same time, synthetic blend motor oil is cheaper than full synthetic oil. However, let us inform you that, synthetic oil is not expensive in the end. If you are confused, consider this, standard engine oil has to be changed after approximately 3500 miles, while synthetic oil has to be changed only after 7500 miles. Therefore, synthetic oil reduces the oil replacement by half and synthetic oil is twice as efficient as standard oil.
