Ongoing use of 98-octane fuel, with the increase in cleaning agents, will help to reduce carbon build-up on the engine's valves and injectors.
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.
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.
The good news is that both regular and premium gas have detergents that can reduce carbon deposits to an extent. If you're buying premium, those detergents may be more powerful. Nevertheless, the key to a clean fuel system is to have your vehicle professionally serviced.
A premium unleaded fuel like Shell V-Power 98 has been infused with powerful cleaning agents that remove gunk (aka carbon deposits, if you want to use the technical term) from your fuel injectors and inlet valves, and it also protects against corrosion, which can lead to serious problems for your car's innards.
Shell Premium Unleaded 98 is a premium 98 octane unleaded fuel, designed to provide both performance and efficiency benefits, increasing the power available at the wheels. Suitable for use in many imported and high performance vehicles which are designed to run on premium fuels with a minimum octane rating of 95.
Will higher octane gasoline clean your engine better? No. High octane gasoline doesn't outperform regular octane in preventing engine deposits from forming, in removing them, or in cleaning your car's engine. This is a myth.
Shell Gasoline contains a patented cleaning system that actively cleans intake valves and fuel injectors and protects against future build up. No other gasoline protects better against gunk!
Today's premium fuels contain additives and detergents that help clean fuel injectors and remove carbon deposits inside of engines, thus, incentivizing motorist with engines that use regular fuel to, on occasion, use premium gas to clean their engines.
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.
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.
Sometimes referred to as Ultra Premium unleaded petrol (UPULP), premium 98-octane fuel is the highest octane unleaded fuel, providing higher engine power and performance as well as less pollution, according to providers.
The storage life of petrol is one year when stored under shelter in a sealed container. Once a seal is broken the fuel has a storage life of six months at 20°C or three months at 30°C. The storage life of petrol in equipment fuel tanks is one month.
The higher the rating, the more tolerant of high compression. High octane fuels don't burn hotter.
The best type of gas to put in your vehicle is whatever octane level your car's owner's manual specifies. Generally, here's what you need to know about octane gas types: Regular fuel is 87 octane. Premium is 91 or 93.
Cars that require premium gasoline have high-compression engines, turbochargers, and other high-performance aspects. Not using premium won't necessarily hurt your engine, but you could lose some of the performance of that premium engine you paid for if you use regular or midgrade gas.
According to a Society of Automotive Engineers' study[3], increasing the octane number of petrol can result in reducing fuel consumption of at least 7%[4] . When combined with a small changes to the engine, the octane number increase could reduce CO2 emissions by 20 million tonnes per year from petrol engine vehicles.
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. It won't make your car perform better, go faster, get better mileage or run cleaner.”
Does high octane gas clean catalytic converters? No. Octane is simply a measure of how much heat and pressure a fuel can withstand before exploding, and — in tandem with a properly designed engine — a higher octane fuel can increase performance and efficiency.
98 is primarily used for sports and performance vehicles, or vehicles with 'highly-tuned' engines. E85: One the other end of the scale to E10, E85 is made up of 85% ethanol and 15% petrol.
Regular gas is the lowest octane fuel, which means it is the least stable. You can find out more about octane ratings and how it affects your car here. E85 has higher octane than regular gasoline. This means that E85 is a lot better for your car's engine than regular gasoline.
Retail gasoline stations in the United States sell three main grades of gasoline based on the octane level: Regular (the lowest octane fuel–generally 87) Midgrade (the middle range octane fuel–generally 89–90) Premium (the highest octane fuel–generally 91–94)
Carmakers design engines for a minimum octane rating. If you open the fuel flap of your car and it says 'unleaded petrol only' it means 91 octane fuel is OK. If the fuel flap says 'premium unleaded only' it means you need to use at least 95. If the fuel flap tells you to use 98, that's what you need to do.
Premium gasoline costs a lot more, but, although it doesn't have ethanol and might have a few added detergents, it's not better. Mixing the grades to get 91 or so shouldn't hurt, but it probably isn't saving you much money.
