At some point in your life, you’ve probably wondered whether you should use 93 or 95 octane fuel in your car, but ended up sticking to the one you’re used to just to be safe. In this article, we’re going to debunk some of the myths between these two fuel grades, as well as break down what makes them different.
What is the difference between 93 and 95 octane fuel?
Despite both fuels typically being petrol in their makeup, these two fuel grades do vary in more ways than one. Firstly – price. Yes, there is a price difference between the two octanes and 93 is usually the cheaper one if you’re comparing the two on a Rand per litre scale.
The number 93 and 95 refers to the fuel’s octane rating, and according to Sasol, you will receive more bang (mileage) for your buck when running the lower octane 93 fuel as opposed to 95. This is contrary to what many motorists and experts who have dabbled in both fuel grades have found. Most people who have used both grades in their vehicles report having paid less for 93 and yielded fewer kilometres on the odo. If your vehicle can run on both fuels, we’d encourage you to do some experimenting of your own and see which fuel performs better and gives you more range.
Which grade of petrol should I use in my vehicle?
Before you panic, you should know that using either 93 or 95 octane fuel in your petrol vehicle by accident is not going to destroy the engine. Both grades of fuel are still petrol and it would be a different story if you poured diesel into a petrol car. Performance cars generally run better on 95 and this is normally the recommended fuel for such cars. Experts say it’s with these types of vehicles that you may notice the performance difference offered by 95 vs 93 octanes.
However, we would encourage you to follow your car manufacturers recommendation when it comes to which fuel grade you should use in your petrol-powered vehicle, but you’ll be glad to know that most petrol cars can run on both grades of fuel without hassle.Finally, although the lower octane rating fuel is cheaper, if you do the sums you’ll find that the saving you’ll make by using this fuel is minimal. For instance, if you’re filling up a 50-litre tank with 93 octane instead of 95, based on the current fuel price you’ll spend roughly R908 and make a saving of R10.
