How does Performance oil affect my car Engine?

Whether it’s better hastening off the line in your Holden Commodore, better top-end speed from your BMW M Series, or a few extra clicks in the range from your old diesel, you want to squeeze the best out of your engine.

Performance oil has long been touted as the solution for more power and better fuel efficiency, but is it true?

Engine Oil DOES Affect Performance of your car Engine. The oil you choose for your car’s engine makes a difference in its economy and power production.

Oil viscosity is the main focus here to make it high-performance oil and it all boils down to the basic laws of physics. The lower the engine oil viscosity, the better it works.

That’s why you see oil grades changing from the traditional 10W-30 to 5W-30 or 5W-20, and more recently, 0W-20.

At lower temperatures, engine oils with lower viscosity like a zero weight (that’s the 0W) are more fluid than higher weights.

That matters for one reason: resistance.

Your engine has to work harder to move internal parts with thicker oil in the crankcase, sapping energy before you ever have a chance to use it.

Imagine the difference between stirring a cup of molasses with a spoon as opposed to a glass of water. Not only is it impossible to match the stirring speed with molasses, but it takes more energy.

That’s how it works for moving parts in the engine crankcase.

Two types of performance Oil – Conventional Oil vs Synthetic Oil

By and large, the best oil viscosity is found in synthetic oils.

That’s only because it’s extremely difficult for oil manufacturers to obtain the same properties in conventional oil. When you lower the friction and resistance inside the engine, like you do when you choose low-viscosity synthetic oil, your engine doesn’t need to work as hard.

It can rev up faster and, potentially to a higher max RPM.

And because there’s less energy needed to do it, less fuel is required to obtain that power.

How Much Difference Is There?

It sounds great, doesn’t it? But how much gain is there?

With one high-performance car test with leading synthetic oil, torque improved by less than 1 percent and horsepower was up around 1.5 percent. Fuel efficiency gains were better – up nearly 1 mile per gallon.

Wait a sec… that’s not exactly gangbusters for gains! While the truth is that you’ll squeeze more power and economy from your engine with low-viscosity synthetic oil, you may not actually notice the difference.

Which Oil Should You Choose? Don’t take the minimal gains as a detractor for synthetic oil, though.

It’s still the best choice for your engine, even if it’s not like a rocket booster strapped to the back bumper.

The best benefit of synthetic oil isn’t for more power or fuel-efficiency, but that it reduces engine wear by up to 90 percent. Use your car manufacturer’s recommended grade of performance oil – just switch it up to synthetic to get the benefits.
