What type of petrol should I use?

What's the best petrol for my car? Some cars run optimally on standard premium unleaded, while others run more efficiently on higher octane fuels like super unleaded so check your manual.

What type of petrol is best for my car?

The higher the octane number is, the more resistant the fuel is to pinging in your engine. For this reason, it's recommended you fill high-performance cars with higher octane fuels, such as 98 premium unleaded petrol, since these cars are more likely to burn fuel consistently at higher temperatures than regular cars.

Does it matter what type of petrol you use?

Always refer to your vehicle manufacturer's recommendations before filling up at the fuel station, as the type of unleaded fuel you use does matter. In a vehicle that is recommended to use regular unleaded (91) fuel - you can opt for premium 95 or 98 unleaded fuel. This will not cause any harm to your engine.

Which quality of petrol is best?

What fuel is better 95 or 91?

Put simply, 95 RON is a just a little more 'stable' than 91 RON and resists pinging longer, allowing the engine to do its thing properly. In the process, the more highly tuned engine is a little more efficient, meaning it can make a little more power on the same volume of fuel.

What Fuel Should You Use In Your Car? Fuel Octane Rating Explained | Drive.com.au

Is it OK to mix 91 and 98?

Mixing the grades to get 91 or so shouldn't hurt, but it probably isn't saving you much money. Using anything higher than your manual recommends probably won't help your car's performance – but using lower might save you a few bucks, Leroux says.

What happens if you put 91 instead of 95?

It won't hurt your engine if you use a higher octane fuel. For example, if you use 95 or 98 in an engine designed for 91, that's fine. However, avoid using a lower octane fuel than the minimum recommended by the manufacturer. Using 91 in an engine designed for 95 or 98 is potentially destructive.

When should I use premium petrol?

The only guarantee is that it costs more. However, using a lower-octane fuel than your car manufacturer recommends could result in engine damage over the long term. If you own a high-performance car, the manufacturer might insist you use a premium fuel to ensure maximum driving performance and fuel efficiency.

Does premium fuel give better mileage?

So is Higher Octane Fuel More Efficient? In a word, no. On its own paying for premium gasoline does not make your car run better or get greater gas mileage. Giving your car the fuel it requires to run smoothly and efficiently, without damage to the engine, does make a difference in your fuel mileage.

Does premium petrol improve mileage?

Putting premium fuel in a car whose engine is tuned to run on normal fuel won't have any advantage. There will be no extra power generation, and your car won't go any faster. Also, there won't be any fuel efficiency gains either. All cars are tuned to perform at an optimum level on a certain quality of fuel.

What happens if you put 95 instead of 98?

To achieve that, the engine uses very high temperatures and pressures. 98 petrol can withstand this, allowing the engine to extract the maximum amount of power from the fuel and run at top power. If you used 95 petrol instead, it would explode too quickly under the pressure.

Is there any difference between petrol brands?

“The only difference is that some [brands] will put different additives in their fuel – none of which will have much noticeable difference on your car's engine or performance.”

Is higher octane petrol better?

For the uninitiated, the octane number of petrol signifies its resistance to knock – a phenomenon caused by the auto-ignition of fuel in the combustion chamber that is detrimental to the engine's health. A higher octane rating denotes better knock resistance and translates into improved fuel economy and performance.

Which petrol is best in UK?

Premium fuels

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.

Does premium petrol make a difference?

Petrol contains a chemical component called octane. Premium type petrol has a higher rate of octane component in it. The measure of octane contained inside the fuel decides how well it will function in higher-pressure motors – high octane fuel works more successfully than lower-rated fuels.

Do I really need to use premium unleaded in my car?

If your car doesn't ping using regular, then there's no reason to use premium. The anti-knock level is just fine for your engine. And today's advanced engine controls adjust the engine's timing and fuel mixture to compensate for differing octane levels to prevent pinging or knocking. Many cars only require regular gas.

Does premium last longer than regular?

Sadly, there's nothing in premium gasoline that would make it last longer than other fuels from the pump. Since the distinguishing feature is the higher-octane levels, the only real benefit you gain is lowering the chance of engine knocking, which isn't much of a threat on most modern fuel systems.

What cars should use premium gas?

What happens if you mix premium and regular gas?

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.

Can premium fuel damage engine?

The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging.

Is it worth buying super unleaded petrol?

Super-unleaded petrol can sustain a higher pressure before burning than standard petrol, essentially allowing the engine to produce slightly more power. Super-unleaded burns a little more efficiently than standard petrol, and also helps to prevent pre-ignition in the engine.

Is Super Unleaded better than unleaded?

Super unleaded petrol has a higher octane number (octane numbers are used to measure a fuel's performance) than regular unleaded, and as such burns more efficiently. This means that it should deliver more power but burn less quickly.

Is unleaded 91 the same as 95?

The general rule of thumb is: the difference in fuel efficiency is about 1% per octane rating – 91 and 95 unleaded fuels, for example, have roughly a 4% difference.

Can I put unleaded 91 in my car?

Most cars built after 2000 are compatible with E10. 91: Known as 'Standard Unleaded', 91 petrol is the most common type of petrol available, with most cars able to run on it, unless you have a performance vehicle. 91 is also the ideal petrol for those who use 4-stroke mowers.

What happens when you mix 93 and 95 petrol?

It is okay for you mix different 93 octane and 95 octane fuel as long as your vehicle octane number requirement isn't too far below or above 94 octane, although it is okay to give a higher octane fuel than it is required because it will do nothing to the engine.
