Jeep Grand Cherokee Engine Oil Type And Capacity Guide

Jeep Grand Cherokees are often praised for their durability, off-road prowess, towing capability, and all-weather performance.

And, for the most part, it’s due to their engines.

The Grand Cherokee offers different engine options, such as 3.6L Pentastar V6, 5.7L Hemi V8, 3.0L EcoDiesel V6, etc.

More often than not, these engines turn out to be reliable and provide a decent balance between power and fuel economy.

However, like any engine, they need timely oil changes to work at their max capacity.

Oil Change is not a complex procedure, but most vehicle owners don’t do it by themselves as they don’t have correct information about oil viscosity and the capacity of their engines.

To help you out, I’ve compiled this list of engine oil types and capacities of all Jeep Grand Cherokee models from 1993 to the present.

Without any further ado, let’s begin:

Note: It’s obvious, but I must clarify that the oil capacity value listed below is “with filter.” Simply put, the oil capacity values listed below include the amount of oil required for the engine and the oil filter. That’s because the oil filter is generally replaced during the oil change.

Similarly, I have listed two oil types for some engine options—one for extreme weather conditions and the other for a moderate climate.

Jeep Grand Cherokee ZJ (1993-1998) Oil Type And Capacity

Jeep Grand Cherokee WJ (1999-2004) Oil Type And Capacity

Note: We have recently published a blog post about Jeep 4.0L engine oil type and capacity. You can check that out if your focus is the 4.0L engine only.

Why Should You Change the Engine Oil?

All vehicles are equipped with sufficient engine oil from the factory.

However, this oil gets contaminated with dirt, debris, and metal particles from engine components over time.

This contamination leads to ineffective lubrication, poor heat dissipation, and sludge formation, which can accelerate engine wear and corrosion.

In other instances, engine oil can degrade due to prolonged exposure to high temperatures, causing it to lose its ability to lubricate the engine components effectively.

This degradation often results in changes to the oil’s viscosity.

The best solution in both instances is to drain the used engine oil from your vehicle and replace it with fresh oil of the same viscosity. This procedure is commonly referred to as the ‘Oil Change.’

Does Engine Oil Brand Matter?

While going with a specific brand is unnecessary, you should go with a reputable company when choosing engine oil for your vehicle.

That’s because using lower-quality oils can cause problems to your engine, such as decreased fuel economy, clogged engine components, oil leaks, etc. In some cases, it can even reduce your engine’s overall lifespan.

In short, ensure that the engine oil you’re about to put in your engine is compatible and has the necessary SAE and API certification.

Conclusion

The engine oil type and capacity are crucial factors to consider when performing an oil change.

That’s because a low amount of engine oil will not be able to provide enough lubrication and heat dissipation.

On the other hand, overfilling the engine oil is not a good approach either, as it can lead to foaming, increased pressure, and potentially damage the engine’s seals and gaskets.

Simply put, you need to add the engine oil only up to the amount specified by the vehicle manufacturer.

Likewise, putting too thin or thick oil in an engine can result in inadequate lubrication and overheating.

Fortunately, having read the above tables, you have complete information about the engine type and capacity for your Jeep Grand Cherokee.

With this knowledge, you can confidently perform an oil change on your own.
