Premium petrol usually has a higher octane rating than regular petrol. Octane is a chemical component of petrol, and the amount of octane contained within the fuel determines how well it will work in higher compression engines – high octane fuel works more effectively than lower rated fuels.
Why is fuel so expensive?
It might not be what you think… Critics blame the cost of fuel on many factors, including tax levels and greedy forecourts, but the main reason is far more complex, and hidden deep in a stressed supply chain.
Is super petrol or super diesel worth it?
The one thing that will put most people off using super petrol or super diesel is the higher price of these premium fuels, but if you drive a performance car, it could be worth your while investing in a tankful.
Is premium gasoline better than regular?
Premium gasoline costs about fifty cents more a gallon than regular and has no positive or negative effect on vehicles that can’t take advantage of it. In a consumer notice, the Federal Trade Commission, notes: “In most cases, using a higher-octane gasoline than your owner’s manual recommends offers absolutely no benefit.
Is 100 octane gas better than regular petrol?
While some companies only go for 97 or 98 octane fuel, you can get 100 octane gas at some leading retailers – even at supermarkets – and while it will carry a 10p per litre premium over regular petrol, your performance car will benefit greatly from a higher octane-rated fuel.
Which fuel is best Why?
Natural gas is the best option as a fuel for transportation as it is a cheap and clean fuel. Petrol and diesel release harmful gases. So, they are not suitable. Steam is generated mostly using coal, which also harms the environment.
What are the different types of fuels used in the UK?
Petrol: The most common fuel used to power cars in the UK, unleaded petrol is mixed with bioethanol to make them more environmentally friendly Diesel: Although UK demand has dropped due to some high profile scandals and concerns over diesel’s environmental impacts, common diesel types are regular diesel (low sulphur) and premium diesel†

How do I choose the best fuel for my car?
When choosing what fuel to fill up with, most drivers take three things into consideration: the price, the gas station location, and the quality of the fuel. With fuel prices on the rise, drivers are often finding themselves opting for the cheapest fuel but this may not always be what is best for your car.
What is an ideal fuel?
An ideal fuel burns easily in the air at a moderate rate. It releases a large amount of energy. It should not leave behind any undesirable substances which can be harmful to us. It should not affect the environment adversely. Fuels which are found in their solid state at room temperature are generally referred to as Solid Fuels.
How long does fuel last in a car?
three to six months
Regular gasoline has a shelf life of three to six months, while diesel can last up to a year before it begins to degrade. On the other hand, organic-based Ethanol can lose its combustibility in just one to three months due to oxidation and evaporation. Tracking the age of the fuel in your tank can be a challenge.
How long does gasoline last in a tank?
Different types of fuel have different lifespans. For conventional gasoline, it usually lasts anywhere from three to five months in your gas tank. Diesel fuel can last twice as long, around six to twelve months.
How long does diesel fuel last?
Diesel fuel can last twice as long, around six to twelve months. The reason these numbers are so broad is that it’s hard to tell how old the gas actually is. It may have been sitting inside the gas pump for a month already before you came to fuel up.
How long can gas sit in a car?
By the time you pump your gas, the gasoline could have sat at the gas station for over a month. So if you’re wondering how long can gas sit in a car, the answer is most likely up to three months from the time you fueled up at a gas station. The type of gasoline that has the most extended shelf life is shelf-stable gas.
How long does gasoline last without ethanol?
Advertisement. Petroleum-based gasoline without any ethanol will still succumb to oxidation and volatile compound evaporation in a sealed container or tank, but these processes usually occur more slowly in pure gasoline, so you can usually expect it to last at least six months when properly stored.
Does 95 fuel last longer?
Some argue there’s no difference, while others say that 95 is better for fuel economy and performance – and the answer is both are somewhat correct. Whether or not to use 93 or 95 depends wholly on the car you own, your driving preferences, and the environment in which you drive.
How long does petrol last?
Probably not as long as you think. Once you’ve put fuel in a container you only have a few months before the quality starts to fall away – even less if the fuel is contaminated in any way. Generally speaking, petrol has a shelf-life of six months if stored in a sealed container at 20 degrees – or just three months if kept at 30 degrees.
How long does diesel last?
Diesel, like petrol, is a fuel that can expire. It’s important to store diesel fuel in a container designed to block out heat, water and air, which can speed up the expiry process. Under the right conditions, diesel can last up to twelve months, but by adding a diesel fuel stabiliser, you can make it last even longer. 6
What is 95 octane fuel?
The next step up the octane ladder, 95 octane fuel allows engineers to tune their engines a little more aggressively before causing that uncontrolled ignition (also called pinging or detonation) that can damage an engine internally.
What is 98 RON petrol?
This fuel exists because some engines need a little more octane, but not the full-fat octane experience of PULP. Often called premium unleaded petrol, 98 RON is the fuel you need for high-performance cars with highly tuned engines. But it’s also the fuel specified for many of those modern, small-capacity turbo engines that are in vogue right now.
Is premium petrol better?
One of the main advantages of premium petrol is that it has an official rating. Unleaded premium fuel has an octane rating which shows how well the fuel resists pressure and premature ignition. Premium petrol can also help to reduce friction, resulting in cleaner engine components and a more efficient performance.
Is premium fuel worth it?
If you are a casual motorist, you may have noticed the premium and high-octane fuels for sale at the petrol pumps and wondered if premium fuel is worth it. With promises of better efficiencies, cleaner engines and smoother driving, it’s no wonder these products demand a premium price.
What is extra premium petrol?
Extra premium petrol vs normal petrol The extra premium petrol has an octane number of 93 or higher, and they are generally suitable for high-performance cars. The manufacturers of high-end cars also recommend high octane fuel. Below are the differences between extra premium and regular petrol.
Is it better to run on regular or premium gas?
If your car’s factory-recommended minimum rating is premium, you can technically run on regular or mid-grade gasoline. However, that does mean you won’t get the same performance or fuel economy, so premium fuel is better. Though it is not usually cheaper now, sometimes diesel fuel can be less expensive than regular gas.
Is 98 octane better than 95?
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.
Should I use 98 or 95 octane fuel?
For better performing engines, using the 98-Octane would allow you to be more fuel efficient and allow the engine to function optimally. Using the 95-Octane for these vehicles, would undoubtedly damage the engine in the long run, due to its incomplete combustion. For regular performing engines, using the 95-Octane fuel would be equally beneficial.
Is 95 or 98 better?
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.
What Octane engine do I Need?
The general rule of thumb is that older cars will happily accept anything from standard 91 unleaded all the way up to premium 98 octane petrol. However, newer cars with high compression ratio engines, especially those with turbocharged engines found on many European marques, strongly prefer 95 or 98 octane premium unleaded.
What is the octane rating of petrol?
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. The octane ratings of petrol available elsewhere may differ. What’s the octane rating?
Is 99 octane better than 95?
Put simply, the only difference between these two fuels is their Research Octane Number, with the higher-octane 95 unleaded designed to be more fuel efficient and lead to a smoother engine operation.
Is 99 octane premium fuel better?
I just filled up my car with the 99 octane premium tesco fuel today for the first time and, unless I am imagining things (or it’s the placebo effect), but I think the engine works much more smooth and generally feels much happier and more alive.
Should I use higher octane fuel?
Some cars specify the use of higher octane fuels but drivers are unlikely to see any fuel efficiency benefits, particularly as they will be paying around 14p more a litre for super unleaded. Should I use a premium fuel? Again, this depends on your car.
Is a 99 octane VXR worth it?
Daily dyno tests also revealed that the VXR running on 99 Octane produced 252bhp on average, compared with standard fuelled car’s 235bhp. Thorney Motorsport concludes that it’s worth paying extra for the Tesco 99 Octane fuel, because you can go further on a tank.
Which petrol is better 95 or 97 octane?
The main difference between RON97 and 95 is that RON97 will have higher resistance to knocking on higher pressures in a high-performance engine, which prevents knocking. At the same time, the RON95 is good but will still produce knocking if your car has powerful engines.
What is the difference between 91 and 95 octane fuel?
What’s the difference between 91 and 95 octane fuel? Put simply, the only difference between these two fuels is their Research Octane Number, with the higher-octane 95 unleaded designed to be more fuel efficient and lead to a smoother engine operation.
Is 98 octane petrol better?
By filling up with higher octane fuel you might be giving your engine a helping hand to work more efficiently, but it is not a silver bullet for all motors. 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.
What is the octane of petrol?
If you mix premium unleaded (which has an octane of 95 RON) and super unleaded (97/98 RON) evenly in your tank, you’ll end up with a mixed-grade petrol of around 96 RON.
What happens if you use 91 instead of 95?
If 91 is used in cars requiring higher octane fuel, you run the risk of pre-igniting or “knocking”. This occurs when the petrol combusts early and pushes down against a piston while it is still moving upwards during the compression stroke.
What is the difference between 91 and 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. Is it OK to mix 91 and 98?
Is 95 octane better than 91?
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. Is it worth using 91 octane?
What happens if you put 95 in a car?
You will travel the same kilometres as if you had refuelled with 95. If you put 95 in a car that should run on 98 octane, this will not lead to mechanical failures, or breakdowns. All that will probably happen is you simply suffer a loss of power, or function regularity.
Should I Fill my Car with 95 or 98 octane fuel?

Is 98 fuel worth it?
Depending on the car you own, fuelling up with 98 octane can result in increased performance that will see you produce a little extra power when compared to lower octane petrol. But if you’re driving something older that hasn’t been tuned to run on high-octane, you’ll likely see no tangible benefit.
Is 98 petrol more expensive than 95?
Most drivers believe that 98 petrol is more expensive than 95 petrol because it’s higher quality and better for your car. 98 petrol does cost significantly more: for a typical car, filling with 98 petrol can be about $18 more than using 95. So are you really paying for a better performance when you choose 98?
What is a 98 RON fuel?
The RON stands for Research Octane Number, which refers to a fuel’s ability to withstand pressure before combusting. So 98 RON fuel can handle a lot more pressure than those with a lower RON. Many turbocharged and high-performance engines are designed to produce more pressure to extract more power from the fuel.
What is the difference between Premium 98 and Premium 95?
Premium 98 petrol has a 98 octane rating. Premium 95 has a 95 octane rating, or RON. Huh. Perhaps, I wondered, RON is called something different in Germany, where my car was made?
Which fuel is most economical?
Most petrol-engined cars have to play second fiddle to diesel cars when it comes to fuel economy because diesels are the best at sipping fuel.
Which car has the best fuel consumption?
Best fuel consumption depends on car’s efficiency of course. “ Fuel consume ” means emissions, and “ best mpg cars” means low emission cars. According to our list these are the winners: Both cars are equipped by Start & Stop technology. Most economical petrol car has small petrol engine such as 900cc.
Which engine is the most fuel-efficient?
Fuel efficiency figures or car mileage is what almost every second person is after. Well, this is something that can dig a deep hole in our pockets after so many prices hikes. As of now in the market, they are the diesel engines that are the most fuel-efficient ones. That said, not everyone goes for these engines.
Which fuel has the highest calorific value?
Efficiency of any given fuel is dependent on its calorific value. Among the given options, hydrogen is the fuel with highest calorific value of 150000 kJ/kg. Therefore, hydrogen is considered as the most efficient fuel. Which of the following fuels has the lowest calorific value ?
Are petrol-engined cars better than diesels?
Most petrol-engined cars have to play second fiddle to diesel cars when it comes to fuel economy because diesels are the best at sipping fuel. But since most British buyers prefer petrol and hybrid cars these days, we’ll run through the best cars out there from both worlds, starting with petrols.
Does 97 octane make a difference?
Purchasing a higher octane rating gas won’t do anything for your car. On the other hand, using a lower octane rating than what is recommended by your manufacturer could cause damage to your car’s engine.
Can a fuel have an octane rating of more than 100?
It is possible for a fuel to have a Research Octane Number (RON) more than 100, because iso-octane is not the most knock-resistant substance available today. Racing fuels, avgas, LPG and alcohol fuels such as methanol may have octane ratings of 110 or significantly higher.
What is 87 octane regular?
Blending 87 with 10% ethanol will result in a fuel octane level above 89 hence the lower grade sub-oct for sale as 87 octane regular. You seem to know the actual science behind all this fuel mumbo-jumbo.
Does higher octane make a difference?
These additional processes are what contribute to the higher pricing, but that does not mean the higher octane will offer any advantage over other blends in many engines. Octane does not offer any better fuel mileage, increase engine horsepower, or make the engine start quicker. Higher octane only reduces the likelihood of engine knock or ping.
Can you put 99 octane in a 95 octane car?
Short answer. If your car needs only the lower octane gasoline, then you can use that OR ANY HIGHER OCTANE gasoline/petrol. Your engine won’t know the difference between the required octane rating, or anything higher than that.
Can a car that normally runs on 95 octane petrol run using 91?
Higher-performance vehicles with their high compression ratios usually require 95 octane petrol. But the situation has raised this question: Can a car that normally runs on 95 octane petrol, safely run using 91? The answer is yes and no – and it is all about what’s aboard individual cars.
Can you put a higher octane fuel in a car?
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. Higher octane fuels don’t contain more energy.
Is 89 octane better than 87?
If you opt for a higher octane than your manual recommends—say, 89 instead of 87—yyour car will be perfectly fine, an article on AAMCO’s blog explains.
