The best diesel engine oil Full review

Best diesel engine oil

The engine is the heart of every machine or vehicle therefor, giving it a wrong oil could spell trouble or void your vehicle warranty. But how do we know which oil is the best diesel engine oil as there are so many different engine oils out there? And each of them is claiming to be the best in the market.

Don’t worry; we’ve interviewed the road masters and even pilots. We also collected customer reviews from different third parties. We compiled these reviews and listed the best diesel engine oil brands.

How do we review products and why you should trust us? We sometimes earn a little commission from our selected affiliate links at no extra cost to you. However, this does not compromise the quality of our reviews at all!.

In fact, most of our reviews are coming from different third party sources and here is how we do it.

Why do we need engine oil?

Diesel engines are likely to generate soot and byproducts from combustion. An engine oil is needed to treat the wear. Engine oil is also essential for lubrication and other functions of the vehicle.

Oil change intervals

There are two types of car owners. Those that change their car oil or do maintenance at the due date. And those who wait for the vehicle to break down on the road before they know something is wrong.

Most vehicles are equipped with indicators that tells you when it’s time to change your oil.

There are few things to keep in mind that will help you determine the right time to change your engine oil.

One thing you need to consider is the age of your vehicle. You also need to determine your driving conditions and the type of oil you use.

Therefore, the intervals in which you should change your oil varies greatly depending on the age of your vehicle, your driving conditions and the type of oil you use.

In those days, it was normal to change your engine oil every 3,000 miles. Thanks to modern Lubricants; many engines are now recommended to change oil after every 5,000 to 7,000 miles.

And again, it depends on the type of oil you use. If you are using a full-synthetic motor oil, you may go as far as 15,000 miles!

Cars are like humans; as they get older, their ability to move or function diminishes. Older cars need frequent checkups and services than new cars.

So it’s recommended you check or change your engine oil at least every 3,000 to 4,000 miles.

Types of engine oils and how they function.

SYNTHETIC OIL

The first type of engine oil on our list is called Synthetic oil. This brand is a man-made lubricant consist of a set of synthesized base oils that are mixed with additives.

This oil was developed in 1929. Synthetic engine oil has been around for decades and has been used in almost everything. This oil is not just for cars; synthetic oil is used for daily-driver, high-performance vehicles and even jets!.

Yes; I’m not kidding you. Jets and other high-performance require synthetic oil. In fact, no other engine oil has been able to compete with synthetic over the years. We will talk about the difference between synthetic oil versus conventional engine oils later in this post.

CONVENTIONAL OIL

The second type of oil is called Conventional oil. This brand of oil is also a lubricant derived from crude oil. Thanks to its excellent properties; Conventional motor oil is able to provide lubricant at high temperatures.

Conventional oil is also capable of maintaining its stability for a very long period of time. In fact, Synthetic oil begins its life as Conventional oil and was later modified to enhance its protective and lubricant properties.

HYBRID FORMULA OIL

Hybrid Formula diesel oil is another type of oil, second to the full Synthetic oil. It’s one of the most popular engine oil in the market. This brand is made up of conventional and synthetic ingredients so it offers both benefits.
