Best Synthetic Motor Oil Reviews

A car can’t function without the oil. This is because the moving parts will be worn out due to friction. The oil also helps in reducing the build up of heat in the engine. It actually serves as cleansing agent. The other advantage is that the oil traps all the deposits such as dirt and debris that find their way into the engine.

When looking to buy engine oil, you have the option of choosing between synthetic and conventional oil. Synthetic oil is usually pure because it has been refined through distillation to remove the impurities that come with crude oil.

Due to its purity, synthetic oil doesn’t emit smoke or smell. On the other hand, conventional oil is not pure because it’s not distilled. It therefore emits a lot of smoke and a choking smell.

Although conventional oil is cheaper than synthetic oil, it’s expensive in the long run. This is because it doesn’t last long in the motor.

It actually requires to be changed regularly after doing a few thousand miles. The other disadvantage is that it can’t be recycled. The oil therefore contributes towards the pollution of the environment.

How to Choose the Best Engine Oil

There are many brands of engine oils in the market. This makes it hard for a newbie to settle for the best deal. For a start, the best brand will definitely have many customer reviews than an emerging brand. When choosing engine oil, you should consider its ability to run on both gasoline and diesel engines.

Oil that supports both types of engines is better because you will not buy two types of oils which in return helps you save money.

It’s also advisable to settle for a brand that has been approved by major automakers. Such a brand will offer an excellent performance. In fact, when a brand bears certification from major manufacturers such as Ford and BMW is the best because such companies are very good in testing consumer products.

The good thing is that some brands exceed the requirements that are specified by these manufacturers. Besides that, the oil should retain its liquid state when exposed to high temperatures. Ordinary oils tend to breakdown when subjected to a lot of heat. Such an oil is not ideal for an engine that’s run for many hours.

What to Look For in Good Engine Oil

When buying engine oil, you should settle for a brand that works well regardless of the changes in weather. There are oils that freeze during winter because they can’t withstand low temperatures. When this happens, the engine of the car or any other equipment takes long to start due to the fact that the oil flows slowly.

There are also others that evaporate when you drive in extremely hot climate.  It is also important to consider the viscosity of the oil. This is normally abbreviated SAE 0W. The lower the number before W, the better.

Most oils have a viscosity of 5W. Such oil can remain thick despite being exposed to harsh weather conditions. This thickness helps in keeping friction at bay because the moving parts can’t come into contact when the engine is turned on.

You don’t have to settle for an expensive brand because competition among manufacturers has led to the emergence of low budget oils. Good oil comes packaged in a plastic corrosion.

This kind of packaging gives you the convenience of carrying the container to wherever you are going. Besides that, buying oil in 5 quart is economical than settling for 1 quart. High quart means you are getting more oil.
