The Types Of Gas A Nissan Sentra Takes (Explained)

Our team is determined to give our readers research-based authentic explanations of their queries. Today, we will look at the gas requirements of a Nissan Sentra. Before we dive into the crucial details of the dos and don’ts, here’s a quick summary of what gas Nissan Sentra would take.

Nissan Sentra comes in four main displacements; 1.6L, 1.8L, 2.0L, and 2.5L. All variants run on regular 87 Octane except for the Turbo variants and the V-Spec variants that require 91 or higher octane. E15 and E85 are not to be used, while oxygenated blends can be used, but not more than the recommended volume.

However, it does not tell us the whole story. We will look into each aspect in great detail. First, we will look at all the available trim levels and put all the data in one place for you to see. You will find your exact variant and the type of gas you should use in the tables down below. The data is sorted out according to the generations and production years.

After giving the octane requirements of every variant, we will take a look at several different additives that you should and should not use in your Nissan Sentra. After that, we will go through each variant and give its mileage data. When we are done with the mileage data, we will go through the fuel tank sizes and how much it would cost to fill up, no matter which state you are in.

Fifth Generation Nissan Sentra (1999-2006)

All variants of the fifth-gen Nissan Sentra can run on 87 Octane, no matter what type of transmission you have. There are three different types of transmissions; 4-speed automatic, 5-speed manual, and 6-speed manual.

EngineFuel Requirement
2.0L Inline-4 (Automatic/Manual)Regular 87 Octane
1.8L Inline-4 (Automatic/Manual)Regular 87 Octane
2.5L Inline-4 (Automatic/Manual)Regular 87 Octane

Sixth Generation Nissan Sentra (2006-2012)

To know for sure if your engine is the one which requires the premium gas, take a look at the engine number. If the number reads QR25DE Spec-V, you would need to add the premium gas. You can go for the mid-grade 91 octane, but it’s better to go for the 93 Octane.

If, however, you cannot find the higher octane gas, you can use regular gas, only to reach a gas station where you can fill up with higher octane fuel.

EngineFuel Requirement
2.0L inline-4 Automatic transmission with variable gear ratiosRegular 87 Octane
2.5L Inline-4 (Automatic/Manual)Regular 87 Octane
1.8L Inline-4 (Automatic/Manual)Regular 87 Octane
2.5L Inline-4 (The year 2007-2012 ) 6-Speed ManualPremium 91 Octane
2.0L inline-4 Manual transmissionRegular 87 Octane

Seventh Generation Nissan Sentra (2012-2019)

There are several variants of Nissan Sentra that require premium gasoline. If you want to know whether or not you have the one that requires the premium gas, you take a look at the engine, and if it reads V-Spec somewhere on it, you must use a mid-grade or premium-grade fuel.

EngineFuel Requirement
2.5L inline-4, Automatic (AV-S6)Regular 87 Octane
2.5L inline-4, 6-speed Manual*Premium 91 Octane
2.5L inline-4, 6-speed ManualRegular Gas
2.0L inline-4 Manual transmissionRegular 87 Octane
2.0L inline-4 Automatic transmission with variable gear ratiosRegular 87 Octane
1.8L inline-4 Manual transmissionRegular 87 Octane
1.8L inline-4 Automatic (variable gear ratios)Regular 87 Octane
1.6L inline-4 Turbo, 6-speed manualPremium 91 Octane
1.6L inline-4 Turbo, (AV-S7) AutomaticPremium 91 Octane

Eight Generation Nissan Sentra 2019-Present

The eight-generation is very simple, if you have the 2.0L inline-4 paired with an automatic, you are good to go with regular gas having 87 Octane. But if you have ended up with the 1.6L inline-4 with a turbo on it, premium gas with 93 Octane is recommended. If you are not able to find premium gas, you can use mid-grade as well with 91 Octane.

What Types Of Gasoline Can And Can’t Be Used?

Reformulated Gasoline

Reformulated gasoline is the effort to reduce the emissions released in the form of vehicle exhaust. These reformulated gasoline keep our environment cleaner, if not free of toxins altogether. Nissan is all-in towards these efforts of a greener environment. Most of the fuel pumps these days are solely selling reformulated gasoline.

You can use the reformulated gasoline without a hitch; you will actually be doing a favor for our environment.

Gasoline/Oxygenated Blends Or E-85

According to the owner’s manuals of all the generations of Nissan Sentra, oxygenated blends can be used, however, except methanol. The latest manuals allow up to 5% methanol content if used.

The blend itself should not contain more than 10% of the oxygenate component. MTBE may be added up to 15% as per the owner’s manual. At the same time, the ethanol content should not exceed 10% by volume.

E15 or E85 are not to be used in any of the Nissan Sentra variants. The engine is not designed to run these additives. Any damage to the engine caused by these “not recommended” additives will not be covered under warranty.

Gasoline With Added Materials

Nissan does recommend the use of any additives that are sold commercially for purposes like octane boosting, fuel injector cleaning, intake valve deposit cleaning, etc. Most of the aftermarket additives will affect the fuel system and the engine itself. Therefore, if you use these additives, you will be doing more harm than good; it’s better to avoid these aftermarket additives.

Gasoline With MMT

Nissan does not recommend the use of MMT. These methylcyclopentadienyl manganese tricarbonyl are known to increase the octane ratings. Most race gasses have this additive used in race build engines and are unsuitable for regular engines.

These additives have an adverse effect on the emissions system and will also affect the performance of your Sentra

Biodiesel

Nissan Sentra does not offer a diesel variant, so you won’t be able to use the biodiesel in any of its trim levels.

What If I Hear A Knocking Noise From The Engine After Refilling?

According to the owner’s manuals of Nissan Sentra, the slight knocking sound is nothing of concern; loud knocking, however, can be problematic. If you started hearing this knocking sound right after you had a refill from a fuel station, the most probable cause of this knocking is the low octane.

To get rid of this kind of knocking, you can try adding mid-grade or premium grade. Make sure you are putting the recommended octane in your Sentra. With a higher octane, the knocking should go away. However, if the knocking persists, your engine might need service. Nissan recommends you have your vehicle inspected at a certified dealership.

How Much Does It Cost To Fill Up A Nissan Sentra?

The cost to fill up a Nissan Sentra will vary from state to state. Some states have their gas priced lower than others, while some states outrageously charge a lot. And not all the Nissan Sentras have the same sized fuel tank.

We will look at several states and calculate how much you would be spending on average on a full tank of gasoline. We will put down the maximum and the lowest cost, so you would know how much you would need to spend no matter where you are.

When writing this article, Texas has the cheapest gasoline, priced at $3.086. If you happen to have the 12-gallon tank, a full tank will cost you approx—$ 37. And if you happen to live in California, you will be paying the highest price per gallon, at $4.633. If you happen to have the 14-gallon tank, you would have to spend approx—$65.

With all this data in mind, no matter where you are, you would pay somewhere between $37-$65 for a complete tank of fuel for your Nissan Sentra.
