There are literally high number of questions on engine oils. What type of engine oil is the best for my car? Can I switch from the manufacture recommended engine oil? What are the different grades of car engine oil? When should I replace the engine oil?
To help you make the right choice, we have compiled a list of 4 crucial questions you should ask about your car engine oil. Know these before your next car service is due.
What are the types of engine oils?
While you’re selecting an engine oil for your car, you should know about the two broad categories of oils i.e. – mineral oils and synthetic oils.
- Mineral Engine Oil: Mineral oils are made from petroleum products and are preferred for older models of vehicles. The mineral oil has low oxidation stability due to which it requires frequent changes. Mineral oil is cheaper than its counterparts. Not the best quality.
- Synthetic Engine Oil: Made by mixing several synthetic components, these oils are suitable for high-performance vehicles. The oil change period is longer with synthetic oils for both diesel and petrol engines. Synthetic engine oil provides the best protection for various driving conditions.
- Semi Synthetic Engine Oil: The semi-synthetic oils give you the best of both worlds. The quality of synthetic oils and the good price of mineral oils. Performance and protection are subjective to the car make and model.
What are the different grades of engine oil?
The engine oils in all around the world have been given grades. Based upon their performance, quality, heating point, and their viscosity.
Let’s break it down and have a look at it. As we all know, engine oil is graded keeping viscosity in purview which is notated with the familiar “XW-XX.”
For instance, let’s take a closer look at 20W50.
Here 20 stands for the rating of the oil at 0-degree Fahrenheit or – 17.8 degrees Celsius. It means that the oil must have a specific maximum viscosity/flow at low temperature. The “W” following the number stands for Winter (not weight).
The 50 in a 20W50 means that the oil must fall within certain viscosity limits at 100°C type high temperatures. Once again the lower the number, the thinner the oil: like a 30 oil is thinner than a 50 oil at 100°C etc.
Having a look on the most famous oil grades in the market:
- 0W40: efficient performance in both hot and cold climate. It makes it ideal for modern-day petrol and diesel-driven cars.
- 5W30: Ideal for modern petrol engines. It is cost-effective and has a low viscosity which fits well with modern age petrol engines and gives good fuel efficiency. Most recommended from majority of car manufacturers.
- 10W40: Available in mineral and semi-synthetic variants. Cost-effective option with good performance.

When should you change your engine oil?
The engine of a car varies from brand to brand and you always have to refer to your car manufacturers recommendations. In some cases, the driving conditions also play a big role in deciding the period of when you change your car engine oil. Taking into consideration, the driving conditions and the road conditions. It can surely be said that our driving conditions are quite different from countries like the USA or some European nations. Traffic, stop and go, etc. puts a lot of stress on the engine.
Most engine oil experts recommend changing your car’s oil at the 15000 kms-10,000 kms mark which is the right spot when using synthetic oil. If you use a mineral-based lubricant you should adhere to the 5,000 kms – 7,000 kms mark.
Can you mix mineral and synthetic engine oils?
It won’t harm your engine in the short run and oil being a miscible component won’t leave any sort of residue but may shorten your engine life time in the long term. The negative effect of mixing both the oils might be that you might not get the proper and up to the mark benefits of synthetic oil when you mix it with the conventional one.
Although, if you’re running low on oil and just have a conventional engine oil handy you should always refill it. Some oil is better than no oil.
