Choosing between E-Plus 91 and Special 95 is a common consideration for motorists in the UAE. While Special 95 has a higher octane rating, it also costs more per litre. This often raises the question of whether spending extra on higher-octane petrol offers any real benefits.

The answer depends largely on your car’s engine and fuel requirements. Some vehicles are designed to run on E-Plus 91, while others require or recommend Special 95 for optimum performance. 

Let’s compare 91 vs 95 petrol in the UAE and understand which one makes more sense for your car.

What is the difference between 91 and 95 Petrol?

The numbers 91 and 95 represent the Research Octane Number (RON), which measures how resistant petrol is to engine knocking.

Engine knocking occurs when the air-fuel mixture inside the engine ignites unexpectedly, creating pressure that can affect smooth engine operation. Higher-octane petrol can withstand greater pressure before knocking occurs.

Here's how the two UAE fuel grades compare:

A higher-octane rating does not necessarily mean better fuel quality or more energy. If your car is designed to run on 91 RON, switching to 95 RON may not deliver any noticeable improvement.

How much more does special 95 cost in the UAE?

UAE petrol prices are revised monthly, so the price difference between E-Plus 91 and Special 95 can change.

As of November 2026, the approved petrol prices are:

Special 95 costs AED 0.07 more per litre than E-Plus 91. For a 60-litre fuel tank, the difference works out to AED 4.20 per refill. If you fill the same tank 50 times, you would spend approximately AED 210 more annually on Special 95, assuming the price difference remains unchanged.

The additional expense may be worthwhile if your engine requires higher-octane fuel. However, if your manufacturer approves E-Plus 91, paying extra may not offer any meaningful advantage.

When should you choose special 95 petrol?

Special 95 is the appropriate choice when your vehicle manufacturer specifies 95 RON as the minimum fuel requirement or recommends it for optimum engine performance. High-compression, turbocharged and performance-oriented engines may be designed to benefit from higher-octane petrol.

However, having a turbocharged engine or owning a luxury car does not automatically mean you need Special 95. Fuel requirements can differ between engines, even within the same manufacturer's lineup. Check your owner's manual or the label inside the fuel-filler flap before choosing a grade. If 95 RON is mandatory, avoid using 91 RON.

Does UAE’s hot weather mean you need 95 petrol?

The UAE's high temperatures, long highway journeys and heavy traffic can put additional demands on car engines.

However, hot weather does not automatically mean every vehicle needs Special 95. If your manufacturer approves E-Plus 91, you should follow that recommendation unless the manufacturer specifies otherwise for demanding driving conditions.

Higher-octane petrol also cannot replace regular maintenance. Checking engine oil, coolant levels and tyre pressure remains important, particularly during the UAE summer.

Does 95 petrol improve fuel economy?

Not necessarily. While higher-octane petrol helps prevent engine knocking, it does not automatically reduce fuel consumption. Engines designed for regular-grade petrol generally cannot take advantage of the additional knock resistance offered by premium fuel.

Research by the American Automobile Association (AAA) found no significant improvement in horsepower or fuel economy when vehicles designed for regular petrol were tested with premium fuel.

However, some vehicles that recommend higher-octane petrol may experience modest performance and efficiency improvements under demanding driving conditions.

Based on November 2026 prices, Special 95 is approximately 1.8% more expensive per litre than E-Plus 91. If your car supports both grades, it will need to deliver around 1.8% better fuel efficiency on Special 95 just to offset the additional fuel cost.

What about super 98 petrol?

Super 98 offers a higher-octane rating than both E-Plus 91 and Special 95. It is intended for engines that require or benefit from 98 RON. Some high-performance vehicles specify Super 98 as their minimum fuel requirement, while others recommend it for optimum performance.

However, using Super 98 in a vehicle designed for 91 or 95 RON does not automatically increase power or improve fuel economy.

As with other fuel grades, your manufacturer's specifications should determine the right choice.

91 vs 95 petrol in the UAE: Which one should you use?

There is no universal winner when comparing E-Plus 91 and Special 95. The right choice depends on your vehicle's engine requirements.

• Choose E-Plus 91: If your car is approved for 91 RON and does not require or recommend a higher grade.
• Choose Special 95: If your manufacturer specifies 95 RON or recommends it for optimum engine performance.

• Choose Super 98: If your vehicle requires or recommends 98 RON.

   

For most motorists, following the manufacturer's fuel recommendation is the simplest way to avoid unnecessary fuel expenses while maintaining engine performance.

If you own an imported vehicle, particularly one from the US, pay attention to the octane-rating system mentioned in its owner's manual. The US generally uses AKI, while UAE fuel grades use RON. These ratings are not directly interchangeable.

FAQs

Q1. Is 95 petrol better than 91 in the UAE?

Special 95 has greater resistance to engine knocking than E-Plus 91. However, it is not automatically better for every car. The correct choice depends on the manufacturer's recommended octane rating.

Q2. Can I use E-Plus 91 instead of Special 95?

You can use E-Plus 91 if your vehicle manufacturer approves 91 RON. If the owner's manual specifies 95 RON as the minimum requirement, you should not switch to 91.

Q3. Does the Special 95 give better mileage than the E-Plus 91?

Not necessarily. Higher-octane petrol does not automatically improve fuel economy. Any benefit depends on whether the engine is designed to take advantage of higher-octane fuel.

Q4. Which petrol is best for cars in the UAE?

The best petrol grade depends on your car's engine specifications. Check the owner's manual or fuel-filler label to determine whether your vehicle requires E-Plus 91, Special 95 or Super 98.

Q5. Can I use 91 RON petrol in a US-imported car?

Not necessarily. US fuel pumps generally use AKI ratings, whereas UAE petrol grades use RON. Check your vehicle's manual and confirm the equivalent UAE fuel grade before refuelling.
