When it comes to car maintenance, the first thing a car owner must take care of would be the engine oil levels.
The thing is, no matter how technically fit your car is, so to speak, if your car fuel is running low, your engine will start choking. The real danger, of course, is that it can even fail completely if you drive your car for long enough without adding engine oil.
Our 5 Favorite Best Synthetic Oil For Cars
Now, as far as adding more motor oil to your car’s, well, motor, the procedure itself is fairly straightforward. All you need to do is unscrew the motor oil cap, add the oil through a funnel (or directly from the bottle if the shape of the engine and the parts underneath the bonnet allow it), and then simply screw the cap back on.
That said, there is only one thing you need to pay attention to before you do this – the kind of oil you’re putting in. Roughly speaking, there are three types of engine oil
- Full conventional motor oil,
- Conventional and synthetic blend, (the mixture of the two kinds), and
- Full synthetic motor oil.
All car manufacturers declare what the type of oil is that you need to be using for the engine of your car. If you pour the wrong sort of oil in your motor, you can reduce the engine’s life, because the lubrication won’t be as good.
In this article, we’re going to talk about synthetic motor oils, in particular. So, if your car’s engine runs on synthetic motor oil, sit back, relax, and read through the list of products we’ve prepared for you. In the passages below, we’ve ventured to compile the best synthetic oil consumer reports suggest, so to speak.
Here’s the lot.

What is Conventional Oil and its Limitations?
Older models of vehicles that are used in routine low-mileage travel activities such as commuting, messenger errands, vacation trips and other common trips often use conventional motor oil.
Later models of vehicles, which are designed for more tedious high-mileage travels and sports races, used highly specialized synthetic motor oils.
Conventional or regular oils showed problematic properties in many aspects because of its molecular composition vary in size and shape, making it prone to oxidation that wears out the oil, reducing its potency in preventing friction in moving engine parts. The formation of sludge reduces engine efficiency and longevity of its life.
Types of Motor Oil
- Synthetic blend motor oil – This is made for engines carrying heavy loads regularly, engines operating at high RPMs every day and trailers used in towing. Synthetic blends possess the best oil property to cope with low temperature and to combat oxidation common in older conventional engine oils.
- High mileage motor oil – According to synthetic motor oil reviews, this motor oil is specially formulated for vehicles with 75,000 or more miles used up in travels. The best kinds of high-mileage engine oils use advanced additives that help stop oil leaks in aging seals, helps reduce burn-off, and helps restore engine compression.
Consult a mechanic before filling-up with high-mileage engine oil. Some older vehicle engines models work best with common synthetic oil.
What are Motor Oil Ratings?
Synthetic oil ratings determine the kind of oil fitted for the requirements of your vehicle’s engine. When you want to know “Who makes the best synthetic oil?” this is the answer you are looking for.
The multiviscosity types of engine oil today are labeled with a designation of the oil’s performance at certain levels of temperature. A 5W-30 label means that it flows better at colder temperature compared to a 10W-30 labeled oil rating.
The number before the ‘W’ denotes the viscosity rating when the oil functions at cold temperature or at engine start-up. The letter ‘W’ stands for winter. The number after the ‘W’ shows the oil’s performance level at high temperatures.
Using and Safety Tips
Ask a certified mechanic what is the best synthetic motor oil when it comes to the oil viscosity level fitted for your car and your climate. Using the wrong oil rating may damage your engine, or shorten its life without you noticing it.
Usually, the properties of the engine oil have something to do with the price. The lower temperature or the higher the temperature that the motor oil can withstand, the more expensive it becomes, in most cases.
The Advantages of Synthetic Oil
Minus the impurities, the best synthetic oil should keep your engine clean and keep it cleaner with the aid of formulated additives. When top rated synthetic oil circulates inside the engine, the special additives picks up dirt and impurity deposits.
The best brands of synthetic oil contain only a minimal amount of impurities from its original crude oil form. It could resist better sludge formation preventing unwanted deposits accumulating in the engine.
The early formulation of synthetics had a bad reputation for leaking. The swelling of seals in crankshafts and rocker cover has been noted. Things get worse when owners change back to mineral oil, or when it adds some oil to the engine when no synthetic is available.
The seal of valve covers compress when swelled, and when different oil is added, leaks take place.
The best fully synthetic oil sold today now allows shifting of use between mineral and synthetic oils in the same engine. Adding a quart of conventional oil to an engine crankcase filled with synthetic oil is just fine. In fact, some synthetic oil brands in the market are formulated blends with a substantial mix of refined conventional mineral oil.
A partnership between MIT and Infinium have examined specific areas related to a future synthetic oil magic formula which is hinged on a major strategic advance in lubricant-rheology. They looked at several factors to reduce mechanical losses, such as:
- The benefits of using low viscosity oils
- Testing of advanced synthetic engine lubricant and engine lubrication system concepts
- Theoretically building a model of the friction of lubricated components in the power cylinder, valve train, and crankcase
- On-site control of lubricant properties
Reduction of Engine Friction
Tremendous research and development efforts were exerted in many years to reduce engine friction. Design factors looked upon by engineers include engine component, component materials, and surface characteristics of moving parts. Most importantly, all further improvements inside the engine will eventually shape the formula of future synthetic engine oils, says Victor Wong of MIT.
Actively Reducing Mechanical Losses
Wong said the centrepiece of their pioneering research at MIT from 2002-2007 is focused on measures to reduce mechanical losses. Some of these measures are shown by the advancements in lubricants, surface characteristics of engine components, and component designs.
The Department of Energy of the United States is funding a lubricant formulation program along these lines of research.

The best synthetic oil remains tied to improving engine efficiency. Unlike in the past decades, wherein the automotive industry aimed to build bigger, faster and more powerful engines for our vehicles, today’s consumers, governments, and industries shifted their attention to increased engine efficiency and reduced emissions.
But generally, the future of synthetic motor oil remains to be focused on reducing friction inside the engine’s crankcase.
Until now, only a few lubricant properties were examined. In moving forward, more design variables will be evaluated by scientist all over the world in relevant test engines.
These might include different viscosity modifier polymers and oil base stocks. In the quest for the best synthetic oil, Dr. Wong believes there must be a balance between fuel economy development and improvements in wear protection.
