2020 Jeep Gladiator Oil Type, Capacity & Filter (Full Guide)
The 2020 Jeep Gladiator brings together pickup-truck functionality with the recognizable boldness and solid off-road capabilities of the Jeep Wrangler. The 2020 Jeep Gladiator is, to put it simply, a 4-door Wrangler Unlimited with a longer wheelbase and a 5-foot cargo bed in place of the standard cargo area.
However, there is a lot of confusion around the best type of engine oil your Jeep Gladiator 2020 model needs. In this article, I’ve done the research for you on Jeep-suitable genuine engine oil and oil filters for the 2020 Gladiator.
All information in this article was sourced from the owner’s manual for the 2020 Jeep Gladiator.
What Type Of Oil For 2020 Jeep Gladiator?
Jeep recommends that the 3.6L 2020 Jeep Gladiator use SAE 0W-20 engine oil.
This recommendation of engine oil applies to all the 2020 Gladiator trims: Sport, Sport S, Overland, and Rubicon.
The engine oil and oil filter needs regular checking and replacing on your Jeep to perform in tip-top condition.
The frequency of oil changes and the type of motor oil your Jeep engine needs also depends on your driving style, the climate where you live, and even how old your Jeep engine is.
2020 Jeep Gladiator Oil Type and Capacity
Not all engine oils are created equal since there are many different types of motor oils available, including conventional, high-mileage, and synthetic. Fortunately, finding the ideal oil for your Jeep 3.6L engine requires referring to the manufacturer’s owner’s manual.
The 3.6L Jeep Engine will require 5.0 quarts (4.73 liters) of SAE 0W-20 engine oil. See below for the manufacturer’s recommended engine oil which improves low-temperature starting and vehicle fuel economy.
Manufacturer Recommended
0W-20 Maxpro+ 5 Qts Oil & Filter Change Kit
Oil change kit that includes 5 quarts of 0W-20 Maxpro+ synthetic oil and Mopar OEM filter.
The recommended 0W-20 engine oil is low-viscosity (or thin) motor oil. This will allow your car to perform optimally in cold temperatures and lets the engine oil flow without causing too much friction in your engine.
Another great premium 0W-20 engine oil that a lot of Jeep owners go for is from Valvoline- 0W-20 Full Synthetic Motor Oil.
Autozillo Recommended
Valvoline Extended Protection Full Synthetic Motor Oil SAE 0W-20 5 QT
Valvoline motor oil extends the life of your car by offering the highest level of defense against the four main factors that contribute to engine failure: wear, friction, heat, and deposits. Full synthetic Valvoline SAE 0W-20 is designed to work in the demanding circumstances of modern engines.
If the Maxpro Mopar engine oil isn’t available, then I’d recommend you go for the Valvoline brand.
2020 Jeep Gladiator Oil Filter
Every time you change your engine’s oil, the oil filter should be replaced with a new one. Jeep recommends that Mopar engine oil filters should be used.
Here’s the OEM and direct replacement oil filter that will fit a 2020 Jeep Gladiator. If you’re doing the replacement by yourself, I found that it’s actually much cheaper to buy this genuine Mopar filter online here than at your local dealership.

In OEM packaging, a genuine factory Mopar filter. 3.6L Jeep engine compatible
Does My 2020 Jeep Gladiator Need an Oil Change?
Your car will be the first to let you know if there is a problem with your oil. There may be an engine oil change indicator light in your Jeep. The instrument cluster display will show the message “Oil Change Required” or “Oil Change”. This is part of the vehicle’s automatic oil change indicator system. When you see this light you should service your engine oil as soon as possible, within the next 500 miles (805 km).
If your Jeep is driven primarily at very low engine RPMs, or if it is driven in a dusty and off-road conditions, the engine oil should be changed after 4,000 miles (6,500 km) or 350 hours of engine operation.
Check for the following warning lights on your 2020 Jeep Gladiator instrument cluster, behind your steering wheel:
Oil Pressure Warning Light – illuminates to indicate low engine oil pressure.
Oil Temperature Warning Light – illuminate to indicate the engine oil temperature is too high.
Note that during the first few thousand miles (kilometers) of driving a new Jeep, the new engine may use some oil, so your oil level might drop. This shouldn’t be seen as an issue but rather as a typical aspect of the break-in of the truck as it drives.
