Why Is It Important To Know The Oil Capacity Of Your Jeep Wrangler?
When your Jeep Wrangler is at its proper level, the oil capacity refers to the maximum amount of oil your vehicle can hold. Before buying a vehicle, you should always check its engine oil capacity.
There are various reasons why you should have a clear idea of the engine oil capacity of your Jeep Wrangler.
When you use the right amount of engine oil in your Jeep Wrangler, it’ll help your engine to work efficiently. It’ll provide proper lubrication and ensure your engine has a longer lifespan.
There’s another reason you should know about the engine oil capacity. You would be able to fill it to the right level. If you fill an engine with more oil than its capacity, it’ll put extra pressure on the gasket and seals.
Using too much oil can also lead to foam formation. It makes the engine less efficient.
Similarly, if you don’t put enough oil in the engine, it’ll damage the engine by overheating and increasing friction.
So, it’s necessary for you to have an idea of the engine oil capacity of your jeep Wrangler. It’ll prevent any damage, overload, and overheating in your engine.
Is More Oil Capacity In Jeep Wrangler Better?
Here’s the tricky part. You don’t necessarily need more oil capacity in your Jeep Wrangler to get better performance. Manufacturers optimize the engine with its oil capacity to perform at the highest level.
In fact, using more oil than the specified requirement creates more hassle than benefit. Overfilling an engine can cause the oil to come in contact with the crankshaft, which causes frothing or foaming.
So, having more oil capacity in your Jeep Wrangler is not better. It essentially doesn’t provide the required lubrication level and risks the long-term health of your engine.
Best Oil Type To Use In Different Models Of Jeep Wrangler 3.6L
It’s essential to follow Chrysler MS-6395 specifications for oil and viscosity to gain the optimal performance of your Jeep Wrangler’s engine.
For the Jeep Wrangler 3.6L (2012–2017), I’d recommend motor oil with a viscosity of SAE 5W-20.
And for the Jeep Wrangler 3.6L (2018–2022), my suggestion would be to use motor oil with a viscosity of SAE 0W-20.
The following oils match this oil type mentioned above:
| Model | Jeep Wrangler 3.6L (2012-2017) | Jeep Wrangler 3.6L (2018-2022) |
| Motor Oil suggestion | Mobil 1™ 5W-20 | Mobil 1™ Advanced Fuel Economy 0W-20 |
| Valvoline Full Synthetic High Mileage MaxLife 5W-20 | Valvoline™ Full Synthetic High Mileage with MaxLife™ Technology SAE 0W-20 | |
| Pennzoil Platinum Full Synthetic SAE 5W-20. | Pennzoil Platinum Full Synthetic SAE 0W-20 |
Can You Use Thicker Oil In A Jeep Wrangler 3.6?
No, I don’t suggest you to use thicker oil in a Jeep Wrangler 3.6.
Thicker motor oil implies oil with a higher viscosity. All the engines come with the proper viscosity specification of oil, which they require to run at maximum efficiency.
Using thicker oil than the specified one will create an issue with oil circulation as the manufacturer made the engine with a thinner viscosity in mind.
As a result, the thicker oil will reduce the efficiency of your fuel, starve your engine, and increase drag and damage in your engine.
Conclusion
Jeep Wrangler 3.6 Oil Capacity differs from model to model. The third-generation Jeep Wrangler JK (2012-2017) has more oil capacity compared to the fourth-generation Jeep Wrangler JL (2018-2022).
You can find more specific and detailed information in the user guide of your Jeep Wrangler. Keep in mind that the engine with more oil capacity will not necessarily perform better. Make sure you use the right type of oil in the proper amount.
