It can’t hurt your engine if you use a higher octane fuel. So, for example, if you use 95 or 98 in an engine designed for 91, that’s OK. However, it’s not acceptable to put in a lower octane fuel than the minimum recommended by the manufacturer. Using 91 in an engine designed for 95 or 98 is potentially destructive.
Here’s the thing: you can put a higher octane fuel in a car than the manufacturer’s requirement. No problem with putting 95 or even 98 in a car designed for 91 – except generally you will be wasting money.
Is 98 octane better for your car?
It’s short for Research Octane Number, a measure of the petrol’s octane rating. In Australia, the octane ratings top out at 98 for premium unleaded, before stepping down to 95 premium unleaded, E10 (94 octane) and standard 91 octane unleaded.
Does 98 fuel make a difference?
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.
What happens if you mix 95 and 98?
While this is unlikely to cause major damage to your car, the RAC recommends sticking to the octane recommended for your vehicle. This will ensure efficient performance and avoid engine damage. A spokesperson for the AA said: “Mixing the 95 and 98 octane fuels will not cause any problems.”
Can I use 98 instead of E10?
98RON UPULP generally costs up to 50c per-litre more than E10 so it can be an expensive way to fill your car for very little performance gain, although there are benefits with no ethanol content meaning it is safe to use in all petrol cars, and can help protect the engine on very hot days when there is a risk of poor
Can I use 98 octane instead 95?
Motorists often ask, “even though the manufacturer says use 91 octane petrol, what’s the benefit from using 95 or 98 octane instead?” In short, there’s none; you should use what the manufacturer has specified for your vehicle.
What’s the difference between 95 and 98 petrol?
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.
Premium gasoline is generally considered any type of gasoline with an octane level of 91 or greater, with 91 octane and 93 octane being the most common versions of premium gasoline available at gas stations in the United States (93 octane gasoline may be called “ultra” or “super-premium” in some cases).
Does high octane fuel give more power?
Will premium petrol improve your car’s performance? If your car has a 100 horsepower engine, that is its power output. Using a fuel with a higher octane rating won’t increase that output. It may increase its economy but the margins are likely to be so insignificant you won’t notice them.
When should I use 98 petrol?
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 a nutshell, premium fuel is in fact chemically superior. Octane levels and lubrication aside, premium fuel has the ultimate benefit that is claimed by all the leading brands; it cleans your engine. Cheaper fuels are apparently prone to early ignition in the engine, causing damage and residue in crucial components.
Can I use 97 octane petrol?
As a general rule, you can use a higher-octane fuel than is recommended for your car (although it might well have no discernible advantages) however using a lower-octane fuel than recommended could cause engine damage.
What happens if you put 98 instead of 91?
It can’t hurt your engine if you use a higher octane fuel. So, for example, if you use 95 or 98 in an engine designed for 91, that’s OK.

Is it OK to mix fuel?
Can I mix premium and unleaded gas? Yes, drivers can mix the two types of fuel. The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive.
Will E5 petrol still be available?
Shell. Shell V-Power is the company’s ‘protection grade’ fuel, meaning it will remain as E5. It will be available to the majority of Shell’s 1,000 UK forecourts.
What happens if you put E10 in an unleaded car?
The government suggests that putting E10 petrol in a non-compatible car on a one-time basis should not result in your car’s engine being damaged as a result. That said, it recommends avoiding prolonged use of E10 petrol in a non-compatible car as this can result in long term harm to the engine.
Is Supreme 98 unleaded?
These numbers are called the ‘octane-rating’, and are an indication of how well the fuel resists burning too early inside the car’s engine. Standard petrol is given a 91 rating, while premium unleaded is both 95 and 98.
Can you put E10 in a Unleaded car?
The majority of modern cars running on unleaded petrol today are compatible with E10.
Can I mix 95 octane and 98 octane?
Yes, you can mix the two rated gasoline without any problems as long as the lower octane does not cause pre-ignition problems with the car you put it in.
