Comparing John Deere Oil Filters to WIX, NAPA, and Baldwin Oil Filters

Shop Oil Filters

When it comes to oil filters, not all are created equal. Today, we’re taking a look at the John Deere canister-style filter versus other well-known brands like Baldwin, Wix, and Napa. We’re here to bust the myth that all filters are built the same and show you why the differences really matter. If you stick with me, we’ll break down the construction, materials, and design of each to help you understand which filter is best for your machine.

Spring System

The first thing you’ll notice when you open up these filters is the spring system. On the John Deere filter, we have a smaller spring compared to the Baldwin, which has a slightly larger one. Then, when we move to the Wix and Napa filters (which are made by the same manufacturer), you’ll see they have a significantly larger spring.

Spring size matters because it is responsible for putting pressure on the nut plate inside the filter, holding the filter media in place and ensuring a good seal. On the Wix and Napa filters, this larger spring is necessary because they use a harder plastic sealing material. The extra pressure helps to keep the filter sealed tightly and prevents leaks. The Baldwin, on the other hand, uses a softer rubber-like sealing material, which requires less pressure to maintain a seal, hence the smaller spring. Meanwhile, John Deere’s design is completely different. The filter is actually bonded to the nut plate with adhesive, so the spring is mainly there to maintain the structure of the filter, not to hold the seal in place. This fixed design reduces the need for a heavy spring and ensures a more secure seal.

Pleats

Now let’s talk about pleats—the part of the filter that does the actual job of filtering the oil. When looking at pleats, we’re considering several things: the total number of pleats, the consistency of spacing, and how well the pleats are constructed.

Starting with the John Deere filter, we have a total of 86 pleats that are relatively straight and evenly spaced, ensuring consisten filtration across the surface. The Baldwin filter drops significantly in comparison, with only 67 pleats that are more widely and inconsistently spaced. This can affect the efficiency of the filter. Wix and Napa come in just under John Deere with 78 pleats. Both brands, while better than Baldwin, show minor inconsistencies in spacing as well. So right off the bat, you’re getting more filtering surface area with John Deere, which typically translates to better filtration performance.

One key thing to note here is how the pleats are held together. Both the John Deere and Baldwin filters use a metal crimp to secure the pleats, which adds durability and helps the filter withstand higher pressures. In contrast, Wix and Napa rely on adhesive to hold the pleats together, which may not be as durable over the long term, especially under high pressure.

Nut Plates

Now, let’s dive into the nut plate, which is a crucial part of any oil filter. This is the component that controls the flow of oil in and out of the filter, so it’s important to get it right.

Looking at the John Deere filter, you’ll notice a significant number of large holes in the nut plate. These larger holes allow for better oil flow, particularly during cold starts when the oil is thicker. This is crucial because when you start your tractor on a cold morning, the oil can have the consistency of honey. You want as many openings as possible to allow the oil to move through the filter freely. On the Baldwin filter, we see fewer and smaller holes, which may restrict oil flow more when compared to John Deere. The Wix and Napa filters also feature smaller holes than the John Deere, making it more difficult for oil to flow as freely.

So why does any of this matter?  The number and size of the pleats directly affect how well the filter can clean your oil. More pleats mean more surface area for trapping contaminants. John Deere’s higher pleat count and better spacing give it an edge. The spring and sealing systems also matter because they ensure the filter stays securely in place and doesn’t leak under pressure. John Deere’s bonded design provides a more reliable seal, while the others rely on springs of varying sizes to create enough pressure to hold the filter in place. Finally, the nut plate design is crucial for ensuring your engine gets the oil flow it needs, especially during cold starts when oil is thick. John Deere’s larger and more numerous holes help prevent flow restriction, ensuring your engine gets the oil it needs as quickly as possible.
