I could only get 91 gas when I lived in El Paso and had a GTR. For pro-tuning, I took it to Austin, where they mapped it for both 91 and 93. The two gasoline grades have very different levels of power. The Q60 engine will undoubtedly perform best on 93 despite the fact that it is definitely not a GTR engine. Not to mention, Infiniti makes it very clear that premium fuel should be used. E85 is something I’m not familiar with, but it won’t be near my gas tank.

When a vehicle manufacturer specifies premium fuel, it’s because the fuel system of that specific vehicle is built to function best with higher octane fuel. In an engine that needs premium fuel, using normal petrol could violate your warranty. That is most likely to occur if repeated use results in severe engine knocking or pinging (premature fuel ignition, also known as detonation), which harms the pistons or other engine components. Keep in mind that this only applies to engines that demand premium gas.
Although some manufacturers advise using premium gas, you can also use standard or mid-grade gas. Usually, they mention that using gas with a lower octane rating could affect performance and fuel efficiency. They advise using premium when that starts to become noticeable, or if engine knock starts to happen.
The usage of premium unleaded fuel with an octane value of at least 91 AKI (Anti-Knock Index) number is advised by INFINITI (Research octane number 96). In the absence of unleaded premium fuel, you can use unleaded normal fuel with an octane rating of at least 87 AKI (Research octane number 91), albeit performance may suffer.
Use less than 15% ethanol in the fuel you put in your car. Your car was not made to run on fuel with more than 15% ethanol in it. The emission control systems and devices of the vehicle may suffer if a fuel containing more than 15% ethanol is used in a vehicle not made particularly for a fuel containing more than 15% ethanol. The INFINITI New Vehicle Limited Warranty does not cover damage brought on by such fuel. Never use fuel that contains methylcyclopentadienyl manganese tricarbonyl, an octane booster (MMT). The performance and emissions of a vehicle may suffer if MMT is used as fuel. You might need to speak with your local gasoline retailer for more information because not all fuel dispensers are marked to show MMT content. Keep in mind that MMT cannot be used in reformulated gasoline because of Federal and Californian rules. According to U.S. government rules, ethanol distribution pumps must be marked with a tiny, square, orange and black label bearing the usual acronym or the relevant percentage for that location.
Use of unleaded fuel with a lower octane value than advised can result in strong, ongoing “spark knock.” (“Spark knock” is the sound of metal tapping.) In extreme cases, this may harm the engine. It is advised that you have an INFINITI retailer fix the issue if you notice a heavy spark knock that persists despite using gas with the recommended octane rating or if you hear a consistent spark knock when maintaining a constant speed on level roads. Failure to remedy the situation is vehicle misuse, for which INFINITI disclaims all liability.
The consequences of improper ignition timing, such as spark knock, after-run, and/or overheating, can lead to excessive fuel use or engine damage. If you experience any of the aforementioned symptoms, have your car inspected. You are advised to go to an INFINITI dealer.
But occasionally, while accelerating or going up hills, you might detect a light spark knock for a little period of time. This is not a cause for alarm because, when there is light spark knock for a brief period of time under severe engine load, you obtain the biggest fuel benefit.
You can therefore use ordinary 87 octane fuel, but be alert for spark knock while maintaining a constant speed on level roads, as that is a sign of a problem (such using too little octane fuel, which can harm the engine).
Is premium gas required for an INFINITI Q60?
If you’re at the pump at one of our Eden Prairie gas stations and wondering whether to fill up your INFINITI with normal or premium gas, we’re here to tell you that the answer is yes. In order for your vehicle to operate as intended, INFINITI advises using fuel that is at least 91 octane.
Is premium gas required for my INFINITI?
The premium fuel that your INFINITI consumes delivers the high-octane gasoline that the INFINITI engine requires. Use 91 octane premium unleaded fuel with your INFINITI to get the performance and horsepower you want.
What occurs if premium gas is not used in an INFINITI?
When a vehicle manufacturer specifies premium fuel, it’s because the fuel system of that specific vehicle is built to function best with higher octane fuel. In an engine that needs premium fuel, using normal petrol could violate your warranty. That is most likely to occur if repeated use results in severe engine knocking or pinging (premature fuel ignition, also known as detonation), which harms the pistons or other engine components. Other issues, such as worsened engine performance and poorer fuel economy, may result from using the incorrect gasoline.
As an illustration, the following is what GM states about the matter in the owner’s guide for a car that needs premium:
“Use 91 octane or higher premium unleaded fuel that has been posted on the label. If the octane level is below 91, you risk damaging the engine and voiding the warranty on your car. When using gasoline with an octane rating of 91 or above, the engine requires maintenance if loud banging is observed.”
Keep in mind that this only applies to engines that demand premium gas. Although some manufacturers advise using premium gas, you can also use standard or mid-grade gas. Usually, they mention that using gas with a lower octane rating could affect performance and fuel efficiency. They advise using premium when that starts to become noticeable, or if engine knock starts to happen.
Will 87 fit in my Infiniti Q50?
You might be curious about whether ordinary gasoline with an octane rating of 87 can still be used in the Q50. This type of fuel is only permitted in the Q50 if premium gasoline is not available, is the answer to this question. Additionally, this can only occur momentarily, therefore you must exercise the following caution:
- Fill the fuel tank only partially with unleaded normal gasoline before quickly refueling with unleaded premium gasoline.
- When accelerating, avoid using the entire throttle.
Furthermore, even for the generations for which Infiniti doesn’t officially suggest this, you might ponder if premium petrol isn’t always a better alternative. This is not the appropriate course of action, is the response. The car will not profit at all from using fuel with a higher octane level than is advised.
The only engines that can profit from it are those built at 93 octane, which is the reason for this. It is best to abide by this suggestion while using 91 octane in engines. Although using 93 octane won’t harm the car, it will cost more in the long run.

What high-end vehicles don’t require premium fuel?
Although the majority of luxury vehicles need premium petrol, some may run on normal. Premium petrol guarantees that a luxury car operates effectively without accumulating additional wear. Find out which expensive vehicles can use ordinary gas before you start filling your tank. The top ten luxury vehicles that don’t require premium fuels are listed below after consulting experts.
Luxury vehicles typically run on normal petrol. Regular petrol is a benefit, according to the manufacturers of these vehicles, and it will not void your warranty.

What happens if you combine gasses 87 and 93?
Therefore, I might have committed a mistake that could be damaging. I typically fill up my automobile with “normal gas” or gas marked “87.” But just now, I accidentally topped off my half-full tank with some premium gas with the designation “93.” Do I need to worry? What happens when you combine two distinct fuel types?
In less than two minutes, find out if your auto insurance is being overcharged.
When it comes to this kind of thing, it’s always better to be cautious than sorry. The answer is that not much happens when you combine 87 and 93 gas.
Regular, midgrade, and premium gas grades are terms used to describe the octane content of the fuel. Additionally, that is what those numbers 87 and 93 are indicating. Gas with an octane rating of 91 or higher is classified as premium gas, whereas gas with an octane rating of 89 or 90 is classified as midgrade gas.
Higher octane gas is generally better for your engine and will produce marginally better performance. On the other hand, you obtain their average when you combine two distinct octane levels.
You therefore have a full tank of 90-octane gas if you have exactly half a tank of 87-octane gas and half a tank of 93-octane gas.
It will never be an issue to add higher octane gas to an engine made to use lower octane gas. However, if you put regular petrol in an engine that needs premium, you’ll all have performance issues.

Can 87 and 91 gas be combined?
On this site, I frequently write about various fuel types. We have not, however, addressed all of the queries. As a result, we’ll utilize this blog to discuss what happens when you blend various gasolines with varying octane ratings. Let’s begin with a brief response:
It won’t hurt vehicles made to run on regular gasoline to mix regular or mid-grade gasoline (87-89 octane) with premium fuel (91-93 octane). Nevertheless, depending on the vehicle, combining different types of gasoline in vehicles made for premium fuel may cause engine knocking and damage to the fuel system.
That, however, hardly provides a complete response to the query. We’ll get into what occurs when you blend normal, mid-grade, and premium gasoline in more detail below. We’ll examine the effects this has on motorbikes, standard gas-capable vehicles, and premium gas-capable cars. We’ll also investigate what occurs when different gasoline types with varying quantities of ethanol are mixed, as well as whether doing so has any advantages. Read on!

Can premium and normal gasoline be mixed?
Can I combine unleaded and premium gas? Yes, drivers are allowed to mix the two fuel kinds. According to The Drive, the mixture of gas types will produce an octane level somewhere in the center, which the vehicle “will survive.”
