Lots of different American-made SUVs, like the Ford Explorer or the Chevy Tahoe, come with their own fuel requirements.
But for this article, we’re going to specifically focus on the types of gas that the Jeep Grand Cherokee uses, one generation and engine option at a time.
We’ll also be including other essential info such as the Grand Cherokee’s gas tank size and gas mileage, making this even more of a must-read for those who fancy owning this popular mid-size SUV from Jeep!
What kind of gas does a Jeep Grand Cherokee take?
Gasoline-powered Jeep Grand Cherokee models can take 87 to 91-octane unleaded gasoline, while diesel variants can only take diesel fuel.
Jeep Grand Cherokee models equipped with the 2007 to 2009 4.7-liter V8 and 2011 to 2014 3.6-liter V6 engines can also take E85/Flex-Fuel.
The majority of engines released throughout the Jeep Grand Cherokee’s production run are designed to run perfectly fine on regular 87-octane gasoline, but this is only if you don’t go for the top-spec performance engines.
Such engines include the likes of the 6.4-liter HEMI V8 in the SRT-8 model and especially the supercharged 6.2-liter Hellcat V8 engine that powers the Trackhawk trim, both of which require 91-octane gas to achieve their advertised power figures.
Even older-gen engines, such as the 98’ Grand Cherokee Limited’s 5.9-liter V8 and the 3rd-gen model’s 6.1-liter V8 option, also share the need for premium fuel.
As far as Jeep Grand Cherokee models that do not use gasoline are concerned, several generations actually come with diesel engines, though not all of them were released in North America.
There are still a bunch of other things to consider when it comes to fuel types that you can use on the Jeep Grand Cherokee, but we’ll let the next several parts of this guide explain them for you.
Jeep Grand Cherokee Fuel Requirements by Generation and Engine Option
Almost all engine options of all Jeep Grand Cherokee generations require at least 87-octane gasoline, except those with the 5.9-liter, 6.1-liter, 6.2-liter, and 6.4-liter V8 that all require premium 91-octane gas.
The 4th-gen Grand Cherokee diesel engine specifically requires ultra-low sulfur diesel.
1st-Generation Jeep Grand Cherokee (ZJ) (1993 to 1998)
| Engine Option | Minimum Fuel Requirement |
| 4.0L AMC 242 PowerTech Inline-6 (I6)(1993 to 1995) | 87-Octane Gasoline (Regular) |
| 5.2L Magnum V8 | 87-Octane Gasoline (Regular) |
| 5.9L Magnum V8(1998 Limited Model) | 91-Octane Gasoline (Premium) |
| 2.5L VM Motori 425 OHV Inline-4 (I4) Diesel(European Market) | Diesel Fuel |
The first use of the “Grand Cherokee” nameplate started back in 1993 under the “ZJ” designation.
The 1st-gen Jeep Grand Cherokee ZJ brought four different engine options to the table, three of which are gasoline engines, while the remaining one was a 2.5-liter inline-4 diesel only offered for the European market.
Underneath the hood of the base model was a 4-liter PowerTech inline-6 engine, while a bigger and more powerful 5.2-liter Magnum V8 from Chrysler was also available. Both of these engines need at least 87-octane gasoline to avoid engine knock.
By the 1998 model year, a limited model trim was offered that came with its unique 5.9-liter V8, but unlike the first two gasoline engines, this one came with a 91-octane premium fuel requirement according to its manual.
2nd-Generation Jeep Grand Cherokee (WJ) (1999 to 2004)
| Engine Option | Minimum Fuel Requirement |
| 4.0L AMC 242 Powertech Inline-6 (I6) | 87-Octane Gasoline (Regular) |
| 4.7L Powertech V8 | 87-Octane Gasoline (Regular) |
| 4.7L High-Output (HO) Powertech V8(2002 to 2004) | 87-Octane Gasoline (Regular)(Premium Recommended for Max Performance) |
| 2.7L OM612 Inline-5 (I5) Turbo Diesel(International Market) | Diesel Fuel |
| 3.1L 531 OHV Inline-5 (I5) Diesel(International Market) | Diesel Fuel |
The 2nd-generation Jeep Grand Cherokee “WJ” came into the picture in 1999, and though it had one of the shortest model year runs, it made up for it by introducing vastly different styling and more powerful engine options.
The engine options for the 2nd-gen Grand Cherokee were a mix of locally-available gasoline engines and diesel engines only found across the pond.
While Jeep did keep the base 4-liter I6 engine, it ditched the previous gen’s 5.2 and 5.9-liter V8s in favor of a smaller 4.7-liter Powertech V8 that actually made more power than the former two.
A “High-Output (HO)” version of the 4.7-liter V8 came in 2002. Just like the rest of the 2nd gen’s gas engine options, it also requires at least 87-octane gasoline.
However, Jeep does recommend switching to premium fuel for the 4.7-liter HO V8 in order to reach the most optimum power output that it can give from the factory.
3rd-Generation Jeep Grand Cherokee (WK) (2005 to 2010)
| Engine Option | Minimum Fuel Requirement |
| 3.7L PowerTech V6 | 87-Octane Gasoline (Regular) |
| 4.7L PowerTech V8 | 87-Octane Gasoline (Regular)(E-85/Flex-Fuel Capable from 2007 to 2009) |
| 5.7L HEMI V8 | 87-Octane Gasoline (Regular) (89-Octane Recommended) |
| 6.1L HEMI V8(SRT-8 Model) | 91-Octane Gasoline (Premium) or Higher |
| 3.0L OM642 V6 Turbo Diesel(2007 to 2008 in North America) | Diesel Fuel |
The 3rd-generation Jeep Grand Cherokee “WK” ties the 2nd-gen WJ model as having the shortest model year run out of any Grand Cherokee generation, which is about 6 years (2005 to 2010).
As with the previous gen, the Grand Cherokee WK was launched with a completely new exterior look, giving rise to its easily recognizable circular Jeep headlights.
For the 3rd-gen Grand Cherokee, Jeep decided to go big again with its V8 engine options by adding an optional 5.7-liter HEMI V8 as well as a 6.1-liter HEMI V8 exclusive to the top SRT-8 trim.
Should customers of the time prefer a more sensible and toned-down option, a new 3.7-liter Powertec V6 base engine was thrown into the mix, though the previous gen’s 4.7-liter V6 was still made available.
The 3.7-liter V6, 4.7-liter V6, and 5.7-liter V8 options are all capable of running on 87-octane gasoline, whereas the more performance-oriented 6.2-liter V8 engine requires premium 91-octane gas to really wake up all its horses.
It’s also worth noting that the 4.7-liter V6 option was equipped with E85/Flex-Fuel capability from 2007 to 2009, meaning that it can take gasoline with as much as 85% ethanol blended in it.
And for the first time, the US-spec Jeep Grand Cherokee was given a diesel option for the 3rd-gen model from 2007 to 2008, and it came in the form of a turbocharged 3-liter OM642 V6 from Mercedes-Benz.
4th-Generation Jeep Grand Cherokee (WK2) (2011 to 2021)
| Engine Option | Minimum Fuel Requirement |
| 3.6L Pentastar V6 | 87-Octane Gasoline (Regular)(E-85/Flex-Fuel Capable from 2011 to 2014) |
| 5.7L HEMI V8 | 87-Octane Gasoline (Regular) (89-Octane Recommended) |
| 6.4L HEMI V8(SRT-8 Model) | 91-Octane Gasoline (Premium) or Higher |
| 6.2L Supercharged Hellcat HEMI V8(Trackhawk Model) | 91-Octane Gasoline (Premium) or Higher |
| 3.0L VM Motori A630/L630 V6 Diesel | Ultra-Low Sulfur Diesel Fuel |
Simply add a “2” to the previous gen’s design code, and you’ve got the 4th-generation Jeep Grand Cherokee WK2 that started its model year run in 2011.
The previous model’s base 3.7-liter PowerTech V6 was no more and along comes Chrysler’s 3.6-liter Pentastar V6, the same engine that powers the Dodge Charger, Dodge Durango, and even the Chrysler 200.
The Grand Cherokee WK2’s 3.6-liter V6 requires 87-octane gasoline, while E-85/Flex-Fuel capability is also available for the engine from 2011 to 2014.
The optional 5.7-liter HEMI V8 makes its return for the 4th-gen Jeep Grand Cherokee with the same minimum 87-octane gasoline requirement, though using 89-octane gas is recommended to achieve its best performance figures.
The old 6.1-liter HEMI V8 was replaced by the newer 6.4-liter HEMI V8 for the SRT-8 trim, and like its older counterpart, it requires premium 91-octane fuel.
The 4th-gen Grand Cherokee also introduced the powerful Trackhawk model, which is equipped with the same 707-horsepower supercharged 6.2-liter HEMI V8 engine found in Dodge’s Hellcat models.
Of course, with an engine of its caliber, the supercharged 6.2-liter V8 fitted on the Jeep Trackhawk demands at least premium 91-octane fuel more than any other Grand Cherokee engine ever made.
Also, let’s not forget about the sole diesel option for the 4th-gen model, which is a 3-liter V6 diesel engine by VM Motori, and yes, it’s available in the US as well under the “L630” engine code.
Stellantis North America states that the 3-liter V6 diesel engine on the 4th-gen Grand Cherokee specifically requires EN590 diesel fuel for European models, or simply “ultra-low sulfur diesel” fuel anywhere else.
5th-Generation Jeep Grand Cherokee (WL) (2022 to 2023/Present)
| Engine Option | Minimum Fuel Requirement |
| 3.6L Pentastar V6 | 87-Octane Gasoline (Regular) |
| 5.7L HEMI V8 | 87-Octane Gasoline (Regular) (89-Octane Recommended) |
| 2.0L GME Inline-4 (I4) Turbo PHEV(4xe Model) | 87-Octane Gasoline (Regular)(91-Octane or Higher Recommended) |
The 5th and newest generation of the Jeep Grand Cherokee goes by the “WL” designation and is available in three different engine trims.
Both the 3.6-liter Pentastar V6 and the 5.7-liter HEMI V8 make their return for the newest Grand Cherokee WL model, sporting the exact same 87-octane gasoline requirement.
However, a turbocharged 2-liter GME I4 plug-in hybrid (PHEV) engine is now available for the Grand Cherokee 4xe model, which also requires at least 87-octane gasoline.
But since the Grand Cherokee 4xe does have a turbocharged engine, Jeep also recommends using 91-octane gasoline or higher for the best performance.
Types of Gasoline/Fuel That Can Be Used in a Jeep Grand Cherokee
Gasoline-powered Jeep Grand Cherokee models can use TOP TIER detergent gasoline, reformulated gasoline, E-10 or E-15, E-85/Flex-Fuel (Flex-Fuel models only).
Diesel-powered Jeep Grand Cherokee models can use ultra-low sulfur diesel or B5 to B20 biodiesel depending on the generation.
TOP TIER Detergent Gasoline
Many major vehicle manufacturers recommend the use of TOP TIER detergent gasoline for their models, and this also applies to Jeep and its gasoline-powered Grand Cherokee.
Compared to non-TOP TIER brands, fuel brands that use the TOP TIER formulation have higher concentrations of detergent additives in their gasoline, which makes for more effective engine-cleaning performance.
Such detergent additives are able to prevent the build-up of any deposits or debris inside the engine, resulting in the maintenance of optimal engine performance.
Over 60 different fuel brands across North America sell TOP TIER gasoline, and you can spot any of them by simply looking for the “TOP TIER” logo on the gas pump machines.
Reformulated Gasoline (RFG)
It’s stated in the Jeep Grand Cherokees owner’s manual that reformulated gasoline is recommended for its mixture of specific ingredients that reduce toxic emissions from your vehicle.
This is pretty much the same case for a lot of vehicles out there. In fact, many places that have higher levels of air pollution even mandate the use of reformulated gasoline due to its cleaner-burning nature.
About 30% of gasoline sold in the states is in the form of reformulated gasoline, so it’s a relatively common type of fuel that just about any gasoline-powered vehicle on the road can use safely.
Up to 10 or 15% Ethanol (E-10/E-15) (Non-Flex-Fuel Models)
Apart from pure gasoline, ethanol blends can also be used for the Jeep Grand Cherokee, though the exact percentage allowed will be dependent on the generation of the SUV.
By searching through each generation’s owner’s manual, we’ve found that 1st to 4th-gen Jeep Grand Cherokee models until the 2015 model year are compatible with up to 10% ethanol blends (E-10).
As for the 2016 and newer Jeep Grand Cherokee models, they are now capable of taking up to 15% ethanol blended in gasoline, or E-15.
Vehicles that are capable of using E-10 or E-15 fuel are classified as “Non-Flex-Fuel Vehicles” and are equipped with black fuel caps labeled with the appropriate fuel limitations.
Be sure to not go past 10% or 15% ethanol content when filling up non-Flex-Fuel versions of the Jeep Grand Cherokee, as this can result in corrosion and damage to the engine and fuel system components.
E-85/Flex-Fuel (Flex-Fuel Models Only)
A limited number of Jeep Grand Cherokee models were released with E-85/Flex-Fuel capability, meaning that they can be filled up with gasoline containing up to 85% ethanol if you choose to do so.
Jeep Grand Cherokee Flex-Fuel Models:
4th Generation (WK2) – 3.6L Pentastar V6 (2011 to 2014 only)3rd Generation (WK) – 4.7L PowerTech V8 (2007 to 2009 only)
E-85 fuel is primarily used because of its renewability, cleaner-burning mixture, and ability to generate better engine performance compared to just gasoline (if the engine is built for it).
However, do keep in mind that one of the main drawbacks of E-85 or ethanol, in general, is that it has less energy content per gallon than gasoline, meaning that you’ll be getting worse gas mileage overall.
Flex-Fuel vehicles come with their own unique yellow fuel cap with “E-85” printed on it, which will easily indicate that they can take up to 85% ethanol.
As with their non-Flex-Fuel counterparts, do not go past the maximum allowable ethanol content (85%) for Flex-Fuel versions of the Jeep Grand Cherokee to avoid corroding and damaging internal components.
Ultra-Low Sulfur Diesel or B5 to B20 Biodiesel (Diesel Models Only)
Diesel versions of the Jeep Grand Cherokee are a bit harder to come by, though from what we’ve been able to gather, it’s recommended to use ultra-low sulfur diesel for them.
Additionally, 4th-gen Jeep Grand Cherokee diesel variants are also compatible with up to 20% biodiesel (B20), while older diesel models are limited to just 5% biodiesel (B5).
Types of Gasoline/Fuel to Avoid for the Jeep Grand Cherokee
Avoid filling up the Jeep Grand Cherokee with gasoline containing MMT, methanol, leaded gasoline, and gasoline with an octane rating lower than 87.
Gasoline Containing MMT (Methylcyclopentadienyl Manganese Tricarbonyl)
MMT is used as an octane booster in gasoline, but nowadays, major automakers discourage using it due to its tendency to damage your vehicle’s spark plugs and emission system components.
This also applies to the Jeep Grand Cherokee, as the manufacturer even states in the owner’s manual that MMT will not give any performance advantage. It will only negatively affect the spark plugs and the emission system’s normal operation.
The use of MMT also increases the toxicity of fumes being emitted from your vehicle’s exhaust, further adding to the fact that MMT’s octane-boosting benefits are just not worth it for the everyday vehicle.
Methanol
Methanol is also part of the list of fuels or fuel materials that should not be used for the Jeep Grand Cherokee.
Jeep advises to not use gasoline containing methanol in the Grand Cherokee, as it can damage its fuel system components that were not designed to take it.
Leaded Gasoline
In this day and age, leaded gasoline has already been phased out all over the world, making it not suitable for use in the Jeep Grand Cherokee or just about any form of land vehicle there is (excluding some motorsports applications).
What will happen if I use the wrong type of gas?
Using the wrong type of gas, such as using gas with too low of an octane rating than what your vehicle requires, can result in engine knocking, decreased performance, and potential engine damage.
Why do I hear a knocking noise from the engine after refueling?
A knocking noise from the engine after refueling may signify that you have used the wrong gas type or that the fuel used is contaminated.
However, other issues like incorrect air-fuel ratio or ignition timing can also cause engine knock, so having it properly diagnosed by a mechanic is recommended.
Does the Jeep Grand Cherokee get good gas mileage?
The Jeep Grand Cherokee is able to achieve 19 mpg in the city and 26 mpg on the highway using the 2023 3.6-liter Pentastar V6 engine, making it quite impressive in its class in terms of gas mileage.
Jeep Grand Cherokee Gas Mileage Per Generation
The Jeep Grand Cherokee has a combined gas mileage of 13 to 16 mpg (1st gen), 14 to 17 mpg (2nd gen), 10 to 20 mpg (3rd gen), 13 to 25 mpg (4th gen), and 17 to 23 mpg (5th gen) depending on the engine option and type of fuel used.
