2022 lexus nx hybrid gas type

The Lexus NX doesn’t technically require premium gasoline. However, the owner’s manual for the 2022 Lexus NX recommends using premium gasoline to fill up the tank. Learn why you might want to choose premium.

Lexus has recently released the upgraded version of its NX small crossover. This model is now offered with a hybrid engine which delivers an attractive combination of efficiency, performance, and driving pleasure. Also, this new powertrain makes NX eligible for participating in alternative fuel programs offered in some states. In this review, we will discuss whether Lexus NX does in fact need premium gasoline and what other options are available when it comes to gasoline type?

I’ve gotten a few questions on the NX lately around what grade of gasoline to use. The short answer is that you can use regular or premium, but the latter will certainly help you get better performance and fuel economy. So let’s dive in and see what all the fuss is about.

What Is Premium Gas?

Premium gasoline is made from a more refined blend of crude oil than regular unleaded gasoline. It contains additives that help your engine run more efficiently and deliver more power. Regular unleaded gasoline has an octane rating of 87. Mid-grade gasoline has an octane rating of 89. Premium gasoline has an octane rating of 91 or higher. Most cars run on 87-octane fuel without problem.

Premium gasoline can be used for vehicles that were originally designed to run on standard unleaded gasoline, but you won’t get the same benefits as someone who drives a premium vehicle. In fact, using premium gasoline may actually reduce your car’s performance if it wasn’t built to handle this type of fuel. The best way to ensure your vehicle gets enough octane for its specific needs is by filling up with recommended grade at each fill-up.

Why Do Certain Cars Need Premium Gasoline?

The answer lies in the octane rating of each type of fuel. When you pump gasoline into your car, it ignites and burns to create power. The octane rating is a measure of how much pressure is created when that fuel is ignited—the higher the rating, the more pressure, and the less likely it is that knocking will happen. Knocking occurs when unburned fuel ignites in your engine; this results in a knock or ping sound and it can damage your car’s engine over time.

When a car requires the use of premium gasoline, it will usually have an octane rating requirement of 91 or 92. In the United States, premium gasoline is considered to have an octane rating of 91 or higher. Premium gas has a higher octane rating because it contains additives that can make it less prone to knock in some high-performance engines. Knock occurs when fuel is ignited prematurely in an engine’s cylinder. In most engines, this causes a knocking noise as well as a loss of power and efficiency as the engine tries to compensate for the premature ignition.

In order to run at their most efficient, certain car models need to use a more highly refined fuel. This is why it is recommended that some cars use premium gasoline and others can get by with regular.

It is important to note that if your car does not require premium gasoline, using it will not improve your car’s performance in any way. It will only lead to you spending more money.

The Difference Between Regular And Premium Gas

The octane rating measures the fuel’s ability to resist pre-ignition. If your engine has a lot of compression from a turbocharger or supercharger, it tends to have a higher chance of pre-ignition. In that case, premium gasoline will help prevent engine damage caused by pre-ignition.

Now, this doesn’t mean that every car needs premium gasoline—in fact, most cars only need regular unleaded gasoline. Other engines are designed specifically to run on premium gasoline because they use high compression ratios and/or boost technologies such as turbochargers or superchargers that require higher octane levels in order to prevent knock (pre-ignition).

If you drive a luxury car, it probably requires premium gasoline. This is because the engine components and internal design of most high-end vehicles require higher-octane gasoline.

Can You Mix Premium And Regular Gas?

What would happen if you mixed regular gasoline with premium gasoline? That depends on how much of each type of gasoline was mixed together.

If you had a small amount of premium gasoline mixed into regular gasoline, then it would raise the octane level just slightly and likely not have much effect on your engine performance or fuel efficiency at all.

However, if your car is designed for premium gasoline but you accidentally fill up with regular unleaded, then the consequences are not dire: Your car will perform just fine on lower octane fuel.

In fact, you can mix premium and regular gasoline. The manufacturer of your car might recommend it for some cars. The only time you shouldn’t mix premium and regular gasoline is if your car requires premium gasoline, or if you want to avoid knocking in older cars.

Looking at the official Lexus NX manual, in the performance figures on page 16, there is fine print numbers 1 for NX350, NX350h, NX450h+, which means that

Ratings achieved using the required premium unleaded gasoline with an octane rating of 91 or higher. If premium fuel is not used, performance will decrease.

Therefore we can conclude that:

Based on the performance of each engine, the 2022 NX250 is the only model that will require regular gasoline. The 2022 NX350, NX350h, and NX450h+ will all require premium gasoline with an octane rating of 91 or higher.

However, regular gasoline may be used in any Lexus NX model, but you will sacrifice power and performance.

Can You Put Regular Gas In A Lexus NX?

People who own a Lexus NX know why they bought it. What many of these drivers don’t know is whether or not the NX requires premium gasoline. The only definite answer is that you can use regular gasoline in your 2022 Lexus NX 250.

Conclusion

Although premium gasoline is not required for all Lexus NX models it will help improve fuel economy and performance if desired. That’s because premium gasoline burns more completely than regular gasoline. This results in more energy being transferred from the fuel to the engine, so less fuel is needed to gain the same amount of power.

If you own an older model, you should check your owner’s manual or contact a dealership to see what type of gasoline your vehicle needs.
