Does 98 petrol make a difference?
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.
Is it better to use 98 octane?
98 petrol is less likely to be wasted in uncontrolled combustion, which does give more mileage, but in general, the difference is very small. Some drivers do claim 98 gives them greater mileage, but this is possibly more due to their vehicle and driving habits than the fuel itself.
Does higher octane fuel last longer?
The higher the fuel’s octane number, the more resistant it will be to knock. Higher-octane fuels allow engine manufacturers to design more powerful and fuel-efficient engines. Australia’s current standard fuel is 91 Research Octane Number (RON) unleaded and most cars sold here since 1986 were built to accept it.
Does premium fuel actually clean your engine?

What’s the difference between OptiMax and 98 octane?
Optimax (98 OCtane?) is different again and claims to improve the burn of the fuel in the cylinder leading to sharper performance, smoother and cleaner engines and sometime better economy. I have run Optimax for at least four years. I have noticed some improvement in smoothness in 4-cyl Merc engine but not in my 6-cyl Volvo or boxer Subaru.
Which is the highest octane petrol in the UK?
Some retailers sell their own high-performance, high-octane fuels, e.g. Total Excellium Unleaded and Shell V-Power Unleaded, which has an octane rating of 99 RON, the UK’s highest.

How does high octane fuel affect the engine?
Using high octane fuel won’t blow up your engine – the octane rating refers to the fuel’s resistance to pre-ignition (knock/pinking). High-octane fuel doesn’t neccessarily contain any more energy than regular, it allows the engine to produce more power by running at more favourable boost/mixture/timing settings.
Can you use premium fuel on a 4 stroke Yamaha?
I have been told by someone that you can’t use premium fuel for 4 stroke motors….. My question is, when unleaded fuel gets phased out with E10 can you use E10? or have I been told the wrong information and you can use premium fuel? Premium fuel is fine. I have used it in my brand new yamaha 4-stroke and it is fine.
