From the moment a vehicle owner drives out of a dealership, it is important to know the type of fuel the vehicle requires to perform at its optimum level. 

Vehicles have different fuel requirements, and it is crucial for motorists to understand what type of fuel is efficient for their vehicle. To determine the type of fuel a vehicle needs, motorists must consult the vehicle’s manual or enquire with the relevant dealership.

The Difference in Octane Ratings 

The types of petrol available to motorists are based on different octane ratings. The octane rating is a measure of the fuel’s ability to resist knocking during combustion, which is a high-temperature chemical reaction between fuel and an oxidant. 

The Octane 93 and 95 are the standard types of petrol available in South Africa. These ratings are determined by the Department of Mineral Resources and Energy (DMRE). The higher the octane rating the more the fuel can withstand pressure. Compared to octane 95, octane 93 can withstand less compression pressure before it ignites.

Octane 93 is the standard fuel for inland areas as the atmospheric pressure is much lower in inland areas compared to the coast.

Which vehicles need Octane 93 or 95?  

The difference between the two octane ratings is likely to be impactful if it is a high-performance vehicle driven at high speed, while most cars can function efficiently on octane 93 fuel. Automobiles that have more advanced engines with supercharging or turbocharging require higher octane fuel as this helps these engines to improve fuel economy and performance.

If a vehicle is a high-performance one, using a lower octane on a can cause damage to the engine and emissions control system of the vehicle. It may decrease the fuel economy of a car, trigger a rattling noise etc. 

Educating South Africans on being #BeFuelSavvy

To create awareness about the importance of fuel efficiency, the DMRE and Central Energy Fund (CEF) have introduced the #BeFuelSavvy education campaign.  At the heart of the #BeFuelSavvy campaign is the digital fuel buddy ‘ReseGo’ a futuristic and energetic character that seeks to make a difference through informing, educating, and alerting South Africans about the need to be fuel efficient.

ReseGo, which stands for Renewable, Energy, Solar, Electric, Gas and Oil, educates South African households by sharing tips and tricks on how to save fuel, providing the latest on fuel prices and driving engagement across social media platforms such as  TwitterFacebookInstagram and LinkedIn.
