How To Pick the Best Oil Filter for Jeep TJ 4.0?

Only changing the oil filter can not give you perfection in oil changing. It is the industry recommended suggestion to change the oil filter when you are replacing the oil.

For SUV featuring an engine such as the Jeep Wrangler TJ  4.0, you can not just randomly choose any product and install it in your engine. If you can’t make the right fit, you may have leakage of oil and bring a huge loss for you.

Thinking about such issues, we have gone through an extended analysis. Then, we present some significant points that you need to check before buying an oil filter.

Let’s dip into the details.

Vehicle Recommended Thread Size

What your vehicle manual says to install should be the prime factor for you. Check the manual of your 2nd generation Jeep Wrangler and look at what type of oil and oil filter it needs.

If you can be pretty sure of the oil, you are one step ahead of the oil filter buying. Sometimes, these details can be found underneath the front engine cover. You can check if your top cover has the sticker attached here or not.

Before you buy an oil filter, get the right thread size to fit in place correctly.

However, if you cannot get these details, you can measure it from the old filter installed in your vehicle. Measure the diameter and the entire height of the oil filter up to the gasket seal. Then, go for searching the same size oil filter.

Check the Filter Media

Check the description of the oil filter and check how the filtration media is. It is the central part of any oil filter. The efficiency ratio known as the Beta ratio is important here.

Look for the filter media with a minimum of 95% contaminant capturing capacity.  This ratio is considered to be the ‘A’ grade oil filter according to the SAE standards.

Again, check the material of the filter media. You will find the cellulose, synthetic, and synthetic blend filter. Among these, the synthetic filter is the best one and expensive too.

But others are also effective for the Jeep TJ engines.

Filter with Anti-Drain Back Valve

The anti-draining back feature in the valve of the oil filter is essential to have. This type of valve helps your engine from having any dry startup. Also, it hinders the filter from leaking oil when you turn off the engine.

Must Check the Durability

When you decide to buy an oil filter for the 2nd gen Jeep Wrangler with a 4,0L SUV engine, you must ensure the filter’s durability.

Some cheap quality brands make thinner oil filter that easily bends in rough driving or off-road riding. And it can cause leakage of the oil if curled.

So, look for a thicker, stiff, and durable oil filter.

Ensure the Oil Compatibility

Well, most of the oil filters are found to be compatible with all types of oil. Still, you should check it before you make the purchase. There are some brands around that have oil-specific oil filters.

In that case, check the oil filter is compatible with either all oil types or only with the oil you are using in your Jeep TJ.
