changing vehicle oil

You have probably read about articles about how many times you should change your car’s oil many times. However, there is much more to an oil change than how often you change it.

If you need to change your car’s oil. You should buy the oil from Car Smart because they have every type of oil you could possibly need.

You need to change your car’s oil because it becomes contaminated and inefficient after using the car for a long time. The clearance between different parts of a vehicle leads to mixing of oil and fuel which contaminates it.

The evidence that your oil is contaminated is that it will turn black. Your filter will not be able to clean the oil after a certain distance.

The following is what you should know about changing your car’s oil.

 Oil Viscosity

Oil Viscosity

The viscosity of a liquid is essentially it resistance from flowing. Therefore, fluids that flow freely like water are highly viscous while molasses have low viscosity.

The viscosity of oil in your vehicle has a significant effect on its performance. Higher viscosity oil offers more protection when hot, but on the other hand costs you power and mileage. Lower viscosity oil offers more horsepower and gas mileage but there is less engine protection as oil flows between different parts.

Many vehicles have a recommended oil which determines its viscosity but some do not. Therefore, when changing your car’s oil, you will have to carefully choose the oil viscosity.


Many drivers adhere to the 3000-mile oil change rule which has been around for so long it is obsolete for most vehicles. The 3000-mile guideline was created for old cars with very different characteristics to those we see today.

Many experts agree and will tell you that the rule is not applicable today. The reason it works is because it is not likely to have an adverse effect on your car.

Cars today have more tolerance so you should check to see how much mileage your car allows before an oil change. For most modern cars the mileage ranges between 5,000 and 10,000 miles.

Conventional or Synthetic Oil

Synthetic oil is not a new thing and it has been in use for over a decade. The reason that conventional oil still exists is that it is cheap to extract from crude oil and it still works.

Synthetic oils are better because they have less impurities and a more uniform molecular structure. These characteristics make synthetic oil more consistent and durable offering better flow and protection for your engine at varying temperatures.

Synthetic oil costs more than conventional oil. On the other hand, it allows for longer intervals between oil changes. You should consult your vehicle manual to find out which is the best for your car.

Your Oil Filter

No matter how closely you follow the oil change guidelines on your car’s manual, it will not matter if you do not change your oil filters. Even the very best of synthetic oils will quickly accumulate contaminants if you don’t change your oil filters.

Therefore, when changing your oil, it is crucial that you evaluate the state of your oil filters. You should view it as a cheap and easy preventive measure.
