Best Oil Additives

There are many more types of oil additives and these type have even more sub-types. But importantly there are just two general type in which the first one is Oil Stabilizer, we also called it as a viscosity modifiers and the second one is Extreme Wear Additives.

Viscosity is the most important thing in the oil and it changes when the temperature is high. When the viscosity is worse then engine need more power to move.

We need oil stabilizer to over this problem , when oil stay longer than expected, then its mileage is improved, now additive is just a charm for your car.

Old school type of engine need some compounds to stable their performance and also oil additive have some compounds like zincdialkyl-dithiophosphate, phosphorus. Old type of engine need zinc to maintain the performance stability of the engine.

To overcome this need we need zincdialkyl-dithiophosphate, but we’re adding oil additive, which will not only improve the performance of the engine but also extend the life too.

Let me clear one thing here. 

New school types of engine also need oil additives because their friction modifiers reduce the intensity of friction and it is one of the best way to increase the mileage of your car.

Now oil additive works to cover or protect the metal components of the engine.

Oil additive is explained by the term that addition in the oil. Actually there are two particular functions of oil additive.

You just have to choose the right oil additive that actually increase the performance of your car.

How Oil Additive Works

First we have to know what viscosity is and how much it is important for an engine. Viscosity is the rule of measurement to check the efficiency of any motor oil.

If your motor oil have high viscosity then it will mess your engine and if it too flowy then it will flow like a water and miss most of the internal components to lubricate.

Viscosity is also effect the temperature from both internal and external sites.

You can run a car without its body but you can’t without the high performance engine.

Whenever we buy a car then its engine condition and performance is highly measurable.

Oil additive alter the viscosity of you engine’s motor oil and make it efficient as you car needs.

Temperature regulation and a fluid use of all moving parts are essential to your engine.

Difference Between Oil Additive and Fuel Additive

Oil Additive

Oil additive is used to prevent your engine from dark rust that damage your engine instantly and keep operation of engine as efficient as possible.

Fuel Additive

Fuel additive are used to modify the octane rating or corrosion inhibitors for the parts that is associated with the fuel. Mostly fuel additive use for proper lubrication which increase your car’s MPG on streets.

After understanding the chemical purpose, then you will easily figure out which one your engine needs.

Phosphorus: ZDDP is one of the most common oil additive and in which we found zinc and phosphorus both. Phosphorus is widely used to make engine performance as efficient as possible and protecting metal to metal contact.

Zinc: Zinc is always focus on small internal parts of an engine and make it good in performance. Zinc in oil additive works as a performance booster that helps older engines to run properly.

These two ingredients are common in most of the oil additive because oil additive working are based on these chemicals.

Reduce Friction

Better in viscosity oil additive can reduce metal to metal reduction in you engine block. In will increase the life of you engine and also boost performance by reducing possibility of friction.

Increase MPG

Oil additive can also increase your MPG after some time. It will give less stress on your motor. It’s a better long terms investment, you can save much more money in a long run.

Rust Inhibitors

Good choice of oil additive can decrease or reduce the rust inhibitors. Prevention from rust can increase your engine performance and also increase its life.

How Often Do I Change My Oil Additive
