Rislone engine treatment buying guide

Well, if you have come this far, you should know how to choose the best Rislone Engine Treatment oil for your particular need. Before going to any decision, first focus on what your primary needs are.

For example, if your primary concern is to reduce the wear and not the noise, then go for the first product I’ve mentioned here. On the other hand, for those who are worried about the unexpected noise from the engine, the second product may be the best suit for you.

To get the combined result of both of these two, the third product may be what you are looking for. It basically depends on what your particular requirements are and how you want to solve them.

How to use Rislone engine treatment?

There is no hard and fast rule to using this oil in your engine. It’s nothing but some simple steps to follow just like you do while changing engine oil. The steps are as below.

  • First, remove the oil cap from the engine.
  • Open the bottle of Rislone engine oil treatment and pour it inside.
  • Put on the oil cap as it was.

You can use Rislone engine treatment while changing the lubricating oil. You can add it to the oil before or after pouring the oil in. So, it completely depends on when you feel the need to use it.

Talking about how much to use, I’ve already mentioned before that, it depends on what is the condition of the vehicle. For example, the oil treatment can work for 4 to 6 quarts of oil. For regular use of heavy vehicles, using 1 bottle for 5 to 6 quarts is okay.

On the other hand, if the dirt level is too severe, the company suggests using two bottles in that case. You can modify the quantity to some extent as per your requirements. 

Rislone engine treatment vs Lucas

There is a huge debate regarding this thing. Some people claim that Lucas performs the best while others are praising Rislone. I think that depends on what perspective you’re looking for.

Let’s elaborate on what I’m trying to say. What Lucas does is thicken the oil that you use. So, it can perform well for a long time. A similar result can be achieved by shifting to oil of higher viscosity.

But Rislone oil has some additives that provide good protection to wear and also reduce engine noise. So, both of them basically do the same thing in different manners.

  • There are many premium brands that are offering much more features and great performance than Rislone Engine Treatment.
