Short Review on 5W-20 Engine Oil:

If you want to drive smoothly under an extreme cold atmosphere, this engine can be your right selection. So don’t waste your time, pick out this.


  • Thick viscosity proportionately
  • Inadaptable winter viscosity is good for keeping vehicle movable
  • It is significant multi-grade oil
  • Synthetic, in consequence, protects the usual temperature of the engine.

What is 10w30?

The oil name denotes the viscosity of 10 when the engine has not been heated and 30 viscosity when the engine is heated. The W in between the numbers stands for winter. Motor oil can be thick or thin. You can determine the thickness by number. The viscosity starts at and goes further up to 60 while the 60 is most abundant and 0 is the thinnest. 

Why do we need different viscosity in oil? It’s because the engine is generally cold and to start it off the lubrication has to be very quick or the engine life will wear out little by little. Low viscosity oil can perform this task easily. Same way in a hot region, having low viscosity oil won’t be so economic; you’ll require oil with high viscosity.

Is it ok to mix 10w30 and 10w40?

Yes you can mix this oil as they are almost identical. The oils will mix and your engines will perform smoothly. But it’s not like that it is wiser.

So it is wiser to use a certain type of oil and take care of your vehicle as it deserves.

When to use 10w30?

As the oil has a good balance in the mixture, it can better start than the 5w and economy also in some hotter regions. The intention to use this oil must be regular and if you are thinking of saving your engine against wearing out then this is your go-to oil. Of course, you must follow the recommendation list before applying it in your vehicle. 

What does the “w” in a grade of motor oil stand for?

First number of the oil stands for the Weather viscosity. The W stands for the Weather Winter. The lower of this number will be less viscous Your oil will be in the low temperature or cold weather.
