Is it safe to put premium fuel in a car?
There’s no harm in putting premium fuel in a car that normally runs on regular gas, but there’s nothing to gain from it, either. On the other hand, using regular gasoline in a car that requires premium fuel can negatively affect its performance, and may even cause engine damage.
Can you mix regular and premium gas?
It’s not recommended to mix regular and premium gas. However, there are times when there’s little choice in the matter, such as during a fuel shortage. In many cases, switching fuel grades temporarily should have little to no impact on the vehicle. With that said, premium cars require a higher octane fuel.
What are the benefits of premium gas?
The short answer is there are zero benefits for using premium gas if your car is designed for either mid-grade or regular fuel. You might have heard about the term octane rating in a slightly different way. Have you ever gone to the gas station and notice that there are three gas choices? Those are the regular, plus, and power?
What’s the difference between regular and premium gas?
No matter what you’ve heard, premium-grade gasoline won’t do more to clean deposits from your fuel injectors or other parts of the fuel system because today’s regular gas contains the same detergent additives. The main difference with premium is its octane rating — 91 or higher compared with 87 for regular octane.
Can I use 93 octane instead of 91?
Is it OK to use 93 octane instead of 91? Most cars on the road recommend a standard grade 87 or 89. Premium gas 90-93 is completely okay to put in a standard vehicle. Car experts say there is no risk of damage to a standard car using premium fuel.

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 gas burn faster?
Lower octane gas burns quicker than higher octane, and so require less energy to ignite. However, this also means that lower octanes burn more quickly in high pressure environments, and can have a greater tendency to knock.
Is premium gas better?
Octane ratings are plastered all over every gas pump, and, contrary to marketing terminology, ‘premium’ does not necessarily indicate a fuel is ‘better’ for your car as much as whether it is ‘right’ for your car.

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?

Just an equivalent to octane in points above and below Octane. As I learned there is more energy available in a gallon of low octane fuel say 87 vs 93 where as there may be more power available with the 93 at the expense of mpg and more mpg per lower octane!
What happens if you put 87 octane fuel in a car?
In the old days, running 87 octane in a car that required premium fuel would cause the engine to start knocking before the car even left the gas station, but things are different today. If you mistakenly fill up with regular fuel, your car’s ECU will adjust engine timing and performance to work with the lower-octane fuel.
What octane gasoline should I use?
The three tiers of gasoline (87, 89 and 93 octane) are all next to each other on the pump and it’s not hard to absentmindedly push the wrong button. If you opt for a higher octane than your manual recommends—say, 89 instead of 87—your car will be perfectly fine, an article on AAMCO’s blog explains.
Does higher octane burn better?
Yes it will burn as compleatly as lower octane, if the “octane” value is the only difference. But there can be different blends , sometimes the lower “octane” grades are worse though as they’re there to be cheaper. The higher “octane” value only indicates the higher resistance to a damaging too fast explosive combustion .
Will 85 octane hurt my car?
