If the factory filter for your ATV, tractor, or skid steer is out of stock or priced too high, a WIX oil filter cross reference is often one of the first things people look for. The tricky part is matching the right WIX number to your machine — model year, engine variant, and mounting position can all change the answer. This guide explains how WIX part numbers are organized, gives common lookup examples by equipment type, and shows how to confirm fit before installation.
How do WIX Part Numbers Work?
WIX uses a short numeric prefix that tells you the filter family:
- 51xxx — Full-flow spin-on oil filters
- 57xxx — Spin-on filters with extended-service media
- 42xxx — Air filters
- 46xxx — Hydraulic and transmission filters
- 33xxx — Fuel filters
WIX also markets an XP line rated for longer service intervals. Many operators running turbo diesel loaders and excavators prefer XP where oil temperatures stay high for long shifts, though the standard 51/57 series is fine for most applications.
“The prefix tells you the category. The full number tells you the fit. Never assume one without checking the other.”
Common WIX Oil Filter Lookup Examples by Equipment Type
The tables below highlight numbers that often appear in a WIX oil filter cross reference search for the listed machines. Treat them as a starting point only — always confirm the current WIX number against WIX’s own catalog (wixfilters.com) using your serial number or engine code before ordering.
ATV & UTV
| Machine | Commonly Referenced WIX # |
|---|---|
| Polaris Sportsman (mid-2000s–2010s) | 51358 |
| Polaris RZR 800/900 | 51358 |
| Can-Am Outlander (various) | 57902 |
| Yamaha Grizzly 700 | 57935 |
| Honda Foreman/Rancher | 57902 |
Compact & Utility Tractors
| Machine | Commonly Referenced WIX # |
|---|---|
| Kubota L-series (L2501/L3301/L3901) | 51365 |
| John Deere 1025R / 2025R | 51056 |
| Kioti CK-series | 51334 |
| Mahindra 1600/2600 series | 51056 |
If your compact tractor is showing low oil pressure warnings or dark oil between changes, a fresh filter and the correct oil grade often clear it up. You can browse replacement filters for tractors across major brands to compare.
Skid Steers & Track Loaders
| Machine | Commonly Referenced WIX # |
|---|---|
| Bobcat S650 / T770 | 51748 |
| Case SR / TR series | 51748 |
| New Holland C/L series | 51748 |
| Cat 259D / 279D | 57202 |
Excavators
| Machine | Commonly Referenced WIX # |
|---|---|
| Cat 320 / 330 (D-series) | 57202 |
| Komatsu PC200 / PC300 | 57620 |
| Hitachi ZX200 / ZX350 | 57620 |
| Volvo EC210 / EC240 | 57202 |
Wheel Loaders & Backhoes
| Machine | Commonly Referenced WIX # |
|---|---|
| Cat 924 / 930 | 51748 |

Filter fitments shift as manufacturers update engines and housings. Treat any WIX oil filter cross reference chart online — including this one — as a lookup shortcut, not the final answer.
How to Find the Right WIX Filter
Even when you start with a WIX oil filter cross reference, the most reliable path is still WIX’s own catalog search followed by a spec check.
Step 1 — Search WIX’s catalog. Go to wixfilters.com and search by factory part number, competitor number, or by machine (make, model, year, engine). Searching by machine model tends to be safer than searching by engine displacement alone, since two engines with the same displacement can use different filter housings.
Step 2 — Cross-check on a second source. A quick check on parts-crossreference.com or in your machine’s service manual helps catch outdated results.
Step 3 — Confirm the physical fit. Before installing any cross-referenced filter, check these five specs against the original:
- Thread size — M20 x 1.5, 3/4″-16, and M22 x 1.5 are common
- Gasket diameter — Both inner and outer
- Filter length and body diameter — A longer filter may hit surrounding parts
- Bypass valve pressure — Diesel engines usually fall in the 15–25 psi range
- Anti-drainback valve — Needed on horizontal or inverted mounts
Step 4 — Watch for common traps. Ignoring the model year is the most frequent mistake — a machine from 2015 and the same-name model from 2022 often use different filters. Sub-model differences, thread-match-but-wrong-bypass-pressure, and over-filtering (going to a much finer micron rating than the machine was designed for) are the other traps to avoid.
For mixed fleets running different brands and model years, keeping a simple spreadsheet of confirmed WIX numbers per unit saves time later.
Frequently Asked Questions
Is a WIX filter as good as the factory filter?
For most engines, WIX meets the filtration specs published for that application. Some new-machine warranties require documented service with a filter approved by the machine maker, so check your dealer terms before switching during the warranty period.
Can I use the same WIX filter across different skid steer brands?
Sometimes. Skid steers built on shared platforms can share filters, but this is not a rule. Confirm by serial number before buying in bulk for a mixed fleet.
Why does my newer ATV take a different WIX number than my older one?
Engine updates and housing redesigns change the filter fit. If your machine is more than a few years newer or older than a chart entry, look it up fresh.
What is the difference between WIX and WIX XP?
WIX XP uses synthetic media rated for longer service life and higher heat. It’s a common pick for turbo diesel machines running long shifts. Standard WIX filters cover most other applications.
Does an aftermarket filter void my warranty?
Aftermarket parts do not automatically void warranty coverage. Warranty decisions depend on the machine maker’s terms and whether the part is linked to a failure. If your machine is still under warranty, review the dealer policy before switching brands.
Where can I find a cross-reference for an older machine no longer supported by the dealer?
Use WIX’s competitor cross-reference field with any aftermarket number you already have, or search by engine make and model. Machine forums for that brand are also a useful second check.
Conclusion
A careful WIX oil filter cross reference saves time and money, especially across a mixed fleet — but the tables online are only a starting point. Always confirm thread size, gasket, and bypass pressure before installing. When you’re ready to source parts, FridayParts carries a wide catalog of aftermarket filters and other maintenance parts for tractors, excavators, skid steers, loaders, forklifts, and more. You can browse by machine brand or by category to find compatible parts at fair prices.
