Things to Consider When Buying the Best Oil for Flat Tappet Cam Engine

An engine is made out of many components. To protect them from corrosion, keep them cool, and lubricate them, we use engine oil. It is made out of two main elements. One of them is additives and base stock. And the base stock is made from petroleum or synthetic chemicals, and sometimes they are made of a mixture of two.

To know which engine oil is best for your flat tappet camshaft engine, you need to know a couple of things.

Conventional Engine Oil:

Conventional oil is usually used in new cars. They are considered inferior to synthetic and blended oils. It contains detergent elements, friction modifiers, viscosity modifiers, corrosion inhibitors, and many other essential elements. It is a low mileage engine oil, so you will have to change the engine oil often. That’s why it’s mainly used in newer engines.

Full Synthetic Oil:

if you have a high-performance vehicle, it will perform best with full synthetic oil. Full synthetic oil is intended for engines that have higher RPM limits and high temperatures. Also, that can carry large loads. Different synthetic oil is best for various reasons. One will be better at engine protection, while others will be excellent at keeping your engine clean.

Synthetic Blend:

there is some engine oil that is a mixture of both synthetic and conventional motor oil. Basically, it is a conventional oil with a performance boost. It gives you a performance boost while protecting your engine. Also, it is much less expensive than synthetic oil, and it includes many benefits of fully synthetic oil.

High Mileage:

It is exactly as it sounds. This type of engine oil is specifically made for vehicles that are driven for more than 80,000 miles. Usually, high mileage vehicles are likely to have various operating problems. So these types of engine oil contain additives that address common types of issues that come with high mileage engines.

Viscosity:

Every vehicle comes with viscosity ratings. It is given by many different factors like temperature, engine load, and operating temperature. You have to use the same viscosity rating on your vehicle.

Detergents:

It is not the detergent that we use to wash our cloth. Detergent in the engine does not scrub the engine surface, but they remove deposits like solid elements. Detergents in engine oils’ primary purpose are to clean the engine.

Anti Wear Agents:

Sometimes, the engine oil breaks down and creates a lubricating film. So to protect the metal surfaces, an antiwear agent is a must-have. It is made of zinc and phosphorus compounds.

Friction Modifier:

Friction modifiers reduce engine friction and improve the fuel economy. Many people think that anti-wear agents and friction modifiers are the same, but they are not. The friction modifier is made of graphite, molybdenum.

Foam Inhibitors:

When the crankshaft is whipping through the oil, it creates foam. They are not as effective as a liquid lubricant. So companies add foam inhibitors in the engine oil, and it makes the foam bubbles collapse.

Hopefully, if you choose the oil considering these things, you will serve yourself with the best quality oil which will make your riding experience smooth and enjoyable.
