Benefits of synthetic oil

Synthetic motor oils offer a wide range of benefits to your car when used. These benefits are what distance then from conventional oils thus making them to be a great choice for motorists and mechanics around the world. These are as follows:

  • Synthetic motor oils are naturally very high viscosity index. A high viscosity index offers you a more stable viscosity in the different temperature ranges. Apart from performing excellent in low temperatures, the oils resist thinning at higher temperatures leading to greater protection across higher operating temperature range.
  • These oils have great wear protection. The latest car models must handle increased shock loads and the highest torque. Synthetic engine oils offer greater anti-scoring performance, thus increasing gear life under shock loading and high speeds scenarios. They offer outstanding wear protection.
  • Great low temperature performance. Pour point measures the power to flow at low temperatures. Synthetic oils are created to lower internal friction. This leads to excellent flow aspects even at low temperatures. As a matter of fact, your internal parts are protected from wear and tear that usually takes place during a cold start.
  • Since these oils are pure and custom made, they offer low traction force, this means less friction thus lowering fuel consumption or raising your horsepower.
  • Instead of having several hydrocarbons, synthetic engine oils are just pure. Thus, their volatility level is low when compared to mineral oils. As a result, this will reduce oil use and emissions in the air.
  • Also, these oils have a great thermal stability. As the temperatures keep rising in your engine, the oil remains the same.
  • Since synthetic vehicle oils have no impurities, they have a great oxidative stability which means fewer deposits as the oil doesn’t break down.

Factors to consider when buying synthetic motor oil

If it’s your first time choosing synthetic motor oil, there are few things you need to know about them before you pick wrong or less effective oil. With our years of experience, we’ve created a list of some of the most important factors that you need to be well versed with before choosing. These have been discussed as follows:

  1. Type of synthetic oil

Usually, there are two types of synthetic oils. The first type is the synthetic blend oil and the second one is the full synthetic motor oil. Synthetic blend oil is a mixture of synthetic oil and conventional oil. On the contrary, full synthetic oil is where a synthetic base stock is utilized and is not mixed with any additive.

  1. Fuel economy

Highly effective synthetic vehicle oil lowers friction in the internal pathways of your vehicle to increase fuel economy. By reducing friction, the engine will have little work to circulate the oil. High quality synthetic car oil will lead to huge improvements in fuel economy in modern engines.

  1. Viscosity

This is one of the major aspects of any engine oil. Viscosity means how fast the oil flows. Ensure that you select an engine with a thin viscosity so that it can be able to spread evenly all over the engine surface and flow through oil lines at low temperatures, but at the same time it should be thick enough so that it can lubricate and protect the engine of your car.

  1. Special additives

Another crucial factor to consider when picking the best synthetic oil for your car is the special additive it has.  A good number of today’s oils come with special additives or oils blends with useful additives that assist in preventing sludge build-up, deposits and oil leaks inside the engine of your vehicle.

  1. Frictional and lubrication aspects

Acquiring quality synthetic oil will lubricate and lower friction of the internal components of your car engine. The modern blend of synthetic engine oil is created to offer long lasting lubrication and drastically reduce friction to important moving parts of the vehicle engine.

  1. Needs of your vehicle

This is another important feature to look at before acquiring synthetic engine oil of your choice. Check the needs of your car engine so that you can select the most effective oil for it. Different types of car engines need different types of synthetic oils. So, ensure that the oil you’re buying for your car engine is compatible so that you don’t make a mess.

  1. Price

Price is another vital factor to consider. In most cases, people usually prefer cheaper things as they are afraid to spend. Believe me, you are better off with a quality and costly synthetic engine oil rather than going for a cheap one. This is because they perform better and are long lasting too. So, if you want your car to function excellently, go for nothing less than the best.
