Most superchargers and turbochargers are the ones that need higher octane gas. These engines perform better when on premium gas. When buying your car, you will see the recommended octane rating for your vehicle. You should always follow the octane rating on that.
Do I need high octane fuel?
The prices are always higher and a little challenging to keep up with not unless the vehicle is for commercial use. The use of high octane fuel varies depending on your engine, and most regular engines do not need it. But it is important to note that an engine’s octane rating can change over time.
Does high octane petrol affect turbos?
High Octane petrol’s effect on turbos. mikes is right: the octane is required for the engine, not the turbocharger on it’s own. Said another way, the requirement for higher octane is a consequence of having a turbocharged motor vs. a normally aspirated one. We’ve discussed some of the associated issues before.
Does higher octane gas make a difference?
Higher octane gas only works better in engines that require higher octane gas. So, no, it doesn’t make a difference if your engine requires regular octane fuel. Some gas stations may put a different detergent package in their premium fuel, or at least some are advertising such things.
What is the best gas for a turbo engine?
For this reason, high octane premium gas will be the most appropriate to use for such engines. Because turbo engines compress more air in the cylinder, they may pre-detonate and have high chances of knocking. This will have a negative impact on the engine even though modern vehicles have an ECU to compensate for it.
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.
Does premium fuel last longer?
This means that it should burn less quickly whilst delivering more power, but it probably won’t last for a noticeably longer period. If you need to save fuel, you should consider other methods instead of paying more for premium fuel.
Does premium gas last longer than regular gas?
However, ethanol free premium gasoline lasts longer than regular gasoline with ethanol. But the same can be said of ethanol free regular gas, as compared to regular octane gasoline with ethanol. So the question of whether premium gas lasts longer than regular gas comes down to whether the premium gas contains ethanol or not.
How long does gasoline last in a gas tank?
The answer is thankfully simple, as gasoline lasts about as long in a gas tank as long as it does in a gas can. Pure gasoline in a car’s gas tank should last for about 6 months, ethanol gas for up to 3 months, and fuel-stabilized gas for 1 to 3 years.
What is the difference between premium petrol and regular petrol?
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.
Can you buy premium fuel with ethanol?
Some gas stations do sell premium fuel with ethanol. If the premium fuel you buy contains ethanol, then it has the same short shelf life as regular octane gasoline with ethanol. However, ethanol free premium gasoline lasts longer than regular gasoline with ethanol.
Is premium fuel worth it?
Any petrol-engined car can run on premium unleaded petrol, but most cars don’t need it. Most normal cars are designed to use regular E10 unleaded petrol and using premium unleaded is unlikely to result in any performance improvement, although you may see a small improvement in fuel economy.
Should you use premium gasoline?
In a statement, AAA ultimately says it “recommends drivers weigh the potential benefits against the cost of using premium gasoline, if their vehicle does not require it.” And obviously, if your car requires premium fuel, use it. You could experience significant knock and detriments to performance and efficiency otherwise.
What is the difference between premium and regular gas?
Your wallet might thank you. So, what’s the difference between premium and regular gas? Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates.
How much does premium fuel cost?
Premium fuel was typically 8.9 pence up to 11.3 pence more expensive than the standard fuel offered by the garage. Each of our tanks only cost £3 – £5 extra to fill with the premium and although we did notice a difference in some cars, others felt the same.
Can you use regular unleaded gas in a premium car?
Using regular unleaded gas in a car that requires premium fuel reduces engine performance and can cause damage over time. Using premium unleaded does not increase fuel economy. Choosing between premium and regular gasoline is among car owners’ more common decisions.
Does 97 octane make a difference?

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.
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.
What happens if you put 87 octane in a 93 octane car?
If the octane rating is less than 91, you could damage the engine and may void your vehicle warranty.

What happens if you put higher octane gas in your car?
If you use a higher octane fuel in your car, it will run more efficiently and produce less emissions. The higher the octane rating, the more compression the fuel can withstand before detonating. This means that higher octane fuel can be used in higher compression engines without knocking. What Happens When You Put Premium Gas in a Regular Car?
What is the difference between premium and lower octane gasoline?
Recommendedmeans that premium gasoline will provide higher performance (and in many cases, better gas mileage), but that the automobile will operate just fine on lower octane fuel. You should always purchase the higher octane fuel if it is specified as necessary to avoid engine harm.
What is the octane rating of gasoline?
We may now return to those three numbers — 87, 89, and 93 — with this newfound knowledge in hand. To put it another way, gasoline with an octane rating of 87 or above is capable of withstanding the compression ratios used in most automobiles.
Can you put 89 gas in a Mercedes?
The owner’s manual for most Mercedes-Benz models states that you should use only unleaded 91 octane gasoline when using them. The electronic computer system detects the fuel type in the car. This system ensures that the vehicle operates appropriately with this fuel type.
Can a Mercedes use regular gas?
It is okay for a Mercedes to use regular gas, but not for an extended period. Mercedes-Benz recommends its customers use premium unleaded gasoline with an octane rating of 91 or higher. Failure to use premium gasoline will lead to problems such as poor fuel efficiency, the check engine light turning on, and engine knocking.
Can you use 89 octane gas in a Mercedes?
Even if there were no errors in measurement, there are so many factors that affect fuel economy that you can’t possibly know that the gas was the factor in the change in fuel economy. If your Mercedes owner’s manual recommends 91 octane, but says 89 octane should be fine, you can use 89 octane without doing any real harm.
Can you put 89 gas in a 87 car?

They will help to remove some of the build-up of deposits on your engine, but they won’t clean it as thoroughly as a dedicated engine cleaner.
Should you choose a premium fuel octane rating?
Some people think that choosing a premium fuel will achieve better engine performance, and no more dirt or deposits will be built up in the engine. That’s why most automotive experts recommend never to go higher in the octane rating level if your vehicle doesn’t need it.
What does octane mean on a car?
Typically, the octane rating has to do with preventing engine knocking or rattling from happening. There is a very common myth that the higher-octane level, the higher the fuel quality. However, that’s not the case.
Is it OK to use regular gas instead of premium?
In everyday driving, there’s no problem using regular gas, but if you often drive up and down hills or tow, premium fuel will make the engine’s task easier. If you have any question regarding the fuel required for a particular vehicle model, consult the owner’s manual or one of the brand’s dealerships.
Should you use premium gas?
Premium gas sounds like it’s something special, but it translates into paying extra for a higher octane without any performance or fuel-economy benefits for many cars. That’s what we found after running tests at our 327-acre track. Some cars require premium gas, but others simply carry a recommendation that owners use it.
What is the difference between regular and premium gasoline?
(Error Code: 102006) The first difference you notice between regular and premium gasoline is the number that goes with both. Regular gasoline is rated at 87 octane in most states while premium is rated at 91 or 93. What does that mean?
Which fuel should I use if my car only recommends premium gas?
If your car only recommends premium gas then it’s up to you on which fuel to use. AAA found that vehicles which recommended premium fuel saw an increase in performance. The detergents in gasoline will help keep your engine clean and running its best.
Should I use premium gas if my older car has a turbo?
As long as your older car doesn’t have a turbocharger, you can use the cheaper, minimum octane gas without any issues. In some cases, however, if your older car is already producing engine knock, using a premium gasoline could help mitigate this.
Does 95 octane give better mileage?
The most common myth is that a higher octane fuel will give your car more power or better mileage, but that’s not exactly what that means. For gasoline-powered cars to work, air and fuel mix at carefully timed intervals with a spark plug to bring about ignition.
Is higher octane fuel better?
It depends. For most vehicles, higher octane fuel may improve performance and gas mileage and reduce carbon dioxide (CO 2) emissions by a few percent during severe duty operation, such as towing a trailer or carrying heavy loads, especially in hot weather. However, under normal driving conditions, you may get little to no benefit.
Does 87 octane increase mileage?
If the manual specifically says to use the lowest grade use that, the maker knows best. However if it says that the cars were made for 87 or higher your car may be able to take advantage of the higher octane, such is the case with many subarus. However the only way that you will truely be able to tell if it will increase your mileage is to test it.
Should you run 93 octane gas?
The high-octane gas also helped when soft-pedaling the accelerator, elevating 75-mph fuel economy from 17.0 to 17.6 mpg. That won’t make a financial case for running 93 octane, but then you didn’t buy the expensive engine as a rational choice.
What cars use high octane fuel?

What is high octane fuel?
1. High octane fuel produces added performance, but only in engines built and tuned to take advantage of it. Running 93 octane fuel in an engine built to run on 87 octane does absolutely nothing except waste money. What color is jet fuel? Jet fuel is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines.
Does turbo waste more gas?
A turbocharger typically helps a car get better gas mileage because a smaller engine can be used to get the same amount of performance. Expect a turbocharged engine to be about 8% -10% more fuel efficient that the same engine that is not turbo equipped.
Can you use premium gas on a turbo engine?
When you use premium gas on your turbo engine, it will provide more power compared to using regular gas. However, higher octane would not affect lower-compression engines. These engines will not completely burn the fuel leading to wasted gas. There will be no significant increase in performance when you use premium gas on a regular engine.
Do turbocharged cars get better fuel economy?
As I’ve learned through years of testing, turbocharged cars often return much worse fuel economy than their official ratings would lead you to expect. My findings parallel those of other testers. Consumer Reports, for example, concluded that downsized, turbocharged engines typically achieve worse mileage than larger engines without turbochargers.
Can a turbo engine boost without a wastegate?
But correct, in that without the larger mass of air that an engine without a wastegate will not see any boost (example of a non-wastegate equipped turbo engine is used in the Piper Turbo Arrow. The throttle is pushed forward a little at a time and the manifold pressure watched.
Do turbo engines use high octane gas?
Turbo engines are designed for use with high octane gas. These are suitable for cars with engines that operate at higher compression ratios, allowing them to completely consume the fuel’s energy. Turbocharged engines have high compression ratios since they are designed for high performance.
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 is the difference between fuel type and octane rating?
The difference between each fuel type is their ‘ooctane rating’, or the numbers that identify them, such as 91, 95 or 98. The octane rating is an index of a fuel’s heat resistance, which means the fuel’s ability to resist premature burning, which can cause your engine to ‘knock’.
