Let’s get started by taking a look at an overview of this particular motor oil.

Shell Rotella T6 5W40 Overview

First of all, for those who do not know, regular motor oil is that which is made from petroleum – or oil-based motor oil. Synthetic motor oil is made by man. It does not come from natural resources, and so you can feel good about the environment while you are using synthetic. But synthetic motor oil is also really good for your vehicle.

Shell Rotella T6 5W40Synthetic oil costs more because it is much higher quality oil without some of the destructive qualities that wear out your engine that you’ll find with the petroleum-based motor oils out there. This T6 5W40 is synthetic as well as low ash, so you’ll have a much cleaner engine when using it.

Product Features

Now, let’s take a look at some of the features of this oil. There are a lot of great things about it, but the best place to start is with the protection that it offers.

There are three areas where this oil is superior: acid, deposit and wear control. These are three critical areas to look out for because they protect your engine under a variety of driving conditions. Everything from the type of environment you are driving in to the temperature is all affected by these three things.

This oil protects your engine from combustion acids, as well as dirt and silt deposits, which together with a couple of other nice features, help to keep your engine running longer.

The second thing to keep in mind is that this oil is made for heavy-duty use. That means that you are going to be able to keep your engine clean and lubricated even if you use your car all the time. That makes it the perfect engine oil for those who drive their vehicle for a living, or use it as a tool to do their job.

Third, this oil is completely synthetic. There are no petroleum products used so it will adjust to any driving condition and make your engine last longer. Plus, you will notice that you get better performance and better gas mileage. You’ll also notice that this oil has some of the lowest additives of any other motor oil on the market, so you can feel even better about your impact on the environment.

Shell Rotella T6 motor oil is well known among those who use it as a low-viscosity motor oil that will allow your engine to start in a variety of conditions – including extreme cold. In addition to this, there is improved flow at low temperatures because of the way that the oil is manufactured. All of these factors also mean that it is super easy to drain when it comes time to do your oil change – whether you do it yourself or take it to the garage.

Finally, you should know that this synthetic oil meets API CJ-4 and SPI SM specifications – which are extremely difficult to meet. In fact, this oil exceeds the specs required for API SM applications, which is the standard for gasoline engines.

While this is generally intended as motor oil that is used for diesel engines, it can definitely be used for gasoline engines as well.


Some of the advantages of this motor oil include:

  • The fact that it saves energy and therefore saves you money.
  • Plus, you get protection in extreme temperatures and it is compatible with both gasoline and diesel engines.
  • In fact it can even be used in some motorcycle engines.

You will want to check out the technical specs on your bike before you use it in your bike though to ensure that it is going to work properly.


Of course, no motor oil is perfect and even this is no exception. There are some disadvantages to Shell Rotella T6 that you should be aware of, because being informed is the most important part of a review.

  • The main disadvantage is that this isn’t good for gear motors. If you have a gear motor, then you should avoid it because gear motors require thinner oil than this.
  • Another disadvantage is that this is a little bit more expensive than regular motor oil. 

But in terms of quality, as with most things, you get what you pay for!
