Have you used the WO180 oil filter on the KJ 3.7?

[KJlibertyBR]

I can't find the original Mopar oil filter in my city. It's only available online, and it takes 7 days to arrive. The auto parts stores here recommended the WO180, claiming it has the same dimensions. However, it's for 1.8L Volkswagen engines. Has anyone used this filter? Does it make a difference?

I don't know about that WO180. Who makes it? I don't see anything with that number on Rock Auto's parts list. I would avoid it if I were you. I like the MOTORCRAFT FL400S - made by Ford and has a good reputation for it's build quality and materials and it should be readily available - I usually get them at Walmart. They have a high quality silicone drain back valve which can be a big deal in vehicles where the filter tends to drain after you shut the engine off - don't think that's an issue in the 3.7 though. Another good one, if you can find it, is the WIX 51516. I've used both of those. I once watched an Engine Masters show

where they tested and cut apart a bunch of filters and they liked both WIX and Motorcraft. They were looking for good flow through the filter and a media that traps the tiniest particles. They also looked at the internal construction - the strength of the filter media, bypass valve quality etc. The K&N Gold filter won but it was pretty expensive (over $15 at the time). The low end Fram filters they tested were near the bottom so I don't use them any more.

Wega Motors is part of the Argentinian R. Neto S.A. group. Known for manufacturing a wide range of automotive parts, especially filters, for the aftermarket in Latin America.

User and Expert Opinions:

• Negative Experiences: Multiple users on automotive forums have shared concerns. One user reported seeing Wega air filters fail and almost get sucked into the engine, and others have specifically mentioned Wega oil filters causing oil pressure issues. A common sentiment is that they come with less filter material compared to other brands.

I change my 3.7 oil every 2500 miles or so, and I use the Fram P-3600 super filter for the price. The Mopar MO-339 is the factory filter equivalent.

I buy the cheapest filters from rockauto. More than half the time they are old stock, or repackaged better brands (Wix, made in USA, etc.)

As they say "size isn't everything"!

The dimensions may be the same, so it might physically fit.

It might even be the same construction quality, but is it the same specification?

Cartridge filters have a bypass pressure, which means that, when the pressure it take to force the oil through the element exceeds a specific value, then the oil bypasses the element and circulates unfiltered.

This at least prevents oil starvation if the element get clogged by debris - fail safe - but also has a role during engine start and warm-up, when the oil is really thick. Fit a filter with the wrong bypass pressure and you could get oil starvation on a cold start, or have the oil circulating unfiltered most of the time, depending on many variables.
Unless you can confirm that the bypass pressure is the same as oem, don't fit any replacement filter, no matter what the seller says about "This will fit".

I tried to buy a fram 3600 myself this past week, twice. Unfortunately what came in both boxes wasn't a 3600 filter as best I could tell. So I gave up...LOL.

There are much better filters than the Fram 3600 in the same price range. Wix and Motorcraft are better quality.

Yeah I think I'm going to go that way from now on. I don't usually buy Frams too often anyway. I used to buy Napa Gold's but they're a liability nowadays.
