Is unleaded 98 good for your car?

If the fuel flap tells you to use 98, that’s what you need to do. It can’t hurt your engine if you use a higher octane fuel.

Is it worth putting 98 octane fuel?

Depending on the car you own, fuelling up with 98 octane will result in increased performance that will see you produce a little extra power when compared to lower octane petrol. But for example, if you’re driving something older that hasn’t been tuned to run on high-octane, you’ll likely see no tangible benefit.

Does 98 octane clean the engine?

Octane is the measure of a fuel’s ability to resist the phenomenon known as ‘knocking’, not its cleaning ability. Knocking is the uncontrolled combustion of fuel that can destroy engine internals. But that’s not the sort of ‘dirt’ that fuel companies are talking about.

What is the difference between unleaded 95 and 98?

The differences between 95 RON and 98 RON Fuels such as 95 or 98 RON (octane rating number) have a higher resistance to burn which indicates higher levels of energy available for the vehicle’s engine. Using 98 might give 3 per cent reduction over 95, again assuming the computer adjusts the engine parameters.

What fuel is better 95 or 98?

Engine Protection The main difference between 95 petrol and 98 petrol is ‘knock’ resistance. 95 petrol works as well, but if your engine is powerful, it will use higher pressures that 95 petrol may not be able to withstand. If you want to be on the safe side, 98 petrol will offer your engine better protection.

What is the difference between 95 and 98 unleaded gas?

Whether 95 or 98, depends on the compression ratio of the engine. Most engines today are so compressed that unleaded 95 is the best choice. Since unleaded 95 burns faster than unleaded 98, 95 is required for low compression ratios and, vice versa, 98 is required for high compression ratios or high filling levels.

Is 98 Premium Unleaded really better for your car?

Fuel companies such as Shell, Caltex and others often tout this cleaning ability as a unique advantage of 98 premium unleaded, however vehicles today are already equipped with fuel filters to keep out any impurities that can damage components such as the fuel injection system.
