What happens if you put 98 instead of 95?

According to NRMA motoring expert Jack Haley, on average 95 RON can give around 4 per cent lower fuel consumption than 91, assuming the engine computer adjusts to take advantage of the octane difference. Using 98 might give 3 per cent reduction over 95, again assuming the computer adjusts the engine parameters.

Can I put 99 octane in my car?

It is perfectly fine to use a higher-octane fuel than the manufacturer recommends for your car – though it’s unlikely to offer any discernible benefit.

What is the best quality petrol in UK?

Super Unleaded (97/98 RON) Super unleaded is the highest octane petrol that is widely available in the UK. A higher octane rating means that the fuel will tolerate greater compression (more pressure) before it ignites. Ignition under compression is known as pinking and can damage engines.

Can you mix 98 and 95 petrol together?

Is it worth using 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.

Which is better 95 or 98 octane?

98 petrol, which is more stable and resistant to ‘knocking’, is a better choice when it comes to engine protection. 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. In the long run, 98 petrol wins out for engine protection.
