6 Best Synthetic Oil Reviews

It’s funny how somehow when you buy an oil for a scheduled car repair you never come to think what kind of oil it is. Only with time experienced drivers and those fierce car lovers realize that there are at least two types of motor oils: synthetic and conventional. So what’s the difference?

Natural is better, but not always. Synthetic oil is a kind of purified natural oil that is free of any impurities or compounds. These filtered particles could break down under high temperatures and leave different crusts and coating on motor parts. Obviously synthetic oils are better for your vehicle since their molecules are specifically raised and tailored to satisfy the needs of the engine without leaving harmful traces behind.

However, no synthetic motor oil is the same. There are so many kinds of additives blended with the base oil that today you can find an oil that will perform any kind of function: from boosting an octane number to substituting the synthetic oil filter substances. Let’s see what mixes are worth trying:

However, it runs extremely well at -20F for sure.

But one of the biggest advantages of the Shell Rotella synthetic oil is that can easily be found at any store, gas station or repair shop. Every manufacturer claims that their oils are compatible with each other, but we all know that it’s better to stick with one kind whenever possible.
