Should Your Next Car Be Petrol or Diesel?

As car buyers, we have the freedom of choosing a car with a particular powertrain. Primarily, the choices in Malaysia at least, are either petrol and diesel. As such, the variety of options for new cars are pretty diverse. But it all comes down to which type of powertrain you should go for. The age old question comes down to this, petrol or diesel. Which should you go for? In this article, we’ll give you the low down of the pros and cons of both powertrains. For the purpose of this article, we’ll be using the Mazda CX5 as a comparison for both petrol and diesel power.




To many, this is the most common fuel type in Malaysia. In fact, petrol powered cars make up to more than 50% of the entire number count as compared to diesel. So, the buyers can’t be wrong right? Well, the answer is not that transparent as petrol cars do have its own share of good and bad points. For the good points, petrol cars in Malaysia is significantly cheaper to tax. The rate to insure a petrol car is as low as 2.3% and the petrol itself isn’t priced as high as a fortune. As for the bad points, petrol isn’t exactly the most efficient fuel in today’s market as its alternatives. In the case of the Mazda CX5, we get a choice of two different petrol engine variants with different displacements, the 2.0 and the 2.5. Both are naturally aspirated lumps for your information.


If you are looking to purchase a car with an engine capacity of 2.0 and above, bear in mind the cost of the road tax and insurance premiums that comes with the purchase of the specific car. It’s simple, if your next car is a petrol and has a displacement of 2.0 litres, the average price for your road tax is RM379 for non-sedan cars. However, if your next car has a 2.5 engine, expect the average road tax rate to be around RM839.




For the oily movers, diesel is the more efficient option on the market today. Not only that, it also provides better performance which comes to no surprise. Diesel is known as the power house in the automotive world as it provides a lot of torque from down low the rev range. If this was possible in a petrol powered car, no matter whether it is a naturally aspirated car or a turbocharged car, there will be a tremendous impact on fuel economy. However, there are a few downsides to diesel power. 


The first being taxation. In Malaysia, diesel powered cars are taxed a lot higher than its petrol counterparts with some going up as high as RM600 per annum as opposed to RM280 for gasoline. Another downside, is the added weight. Diesel engines weigh a fair bit compared to gasoline cars.




Now that all is said and done, the choice is in your hands. If you were to buy a new car and the final answer comes down to the choice of powertrains, what would it be? Would you go for petrol power because it provides better savings? Or diesel power for better efficiency? Not only that. What about the size of your engine? Would your next car come with a 2.0 or a 2.5? Or even a 2.2 diesel? Let us know your thoughts and comments.
