Hey ya'll...

Getting ready to do my first oil change since moving to a new city and state... I run the Rotella T6 in mine... I was always using a WiX XP filter as it was labeled as being designed for use with synthetic oils...
I can't find that brand anywhere here... What I can find here is the Mopar branded one... It's not labeled specifically for synthetic...but anyone have any knowledge or use with using synthetic with them?
thanks.

I've used the Mopar filter with synthetic many times. Noticed no ill effects in my experience.

For what its worth i have always used a Motorcraft FL-1A on the Mustang with synthetic, as well as regular oil. Never noticed a difference.

thanks... I think I've used the Mopar one before, but it's been quite a while. Just wanted to make sure there wasn't something with the element material itself that was that much different or could possibly cause problems with a full synth. diesel oil like T6.

I learned something new recently... we recently got a newer Corolla for my wife....and it doesn't use a standard self contained replacement filter... you just replace the element and the housing is reusable.

Napa gold, is a rebranded wix filter

I think the filters that are designed (or at least marketed) for synthetic oil are designed to accommodate the extended oil change intervals that you'd typically run with synthetic oil. I'm not entirely sure what that mean in terms of filter design, but I suspect it has something to do with the porosity of the filter media.

My Cherokee is the only vehicle I own that doesn't use a replaceable cartridge-style filter, so go figure.

I was about to mention that too.....

Thanks for the response everyone... I just mainly wanted to make sure that the one I had to use this time wouldn't jack things up.. Good to know about the Napa Gold... will keep that in mind for next change.... I'm surprised that I couldn't find Wix down here.... what the heck? lol

I wasn't gonna mention this but... Not too long ago, I was researching the different Napa/Wix filters. The xp/platinum filters more the longer you use it, whereas the regular Wix/napa gold is good immediately and better suited for the interval most of us use.

NAPA Gold 1515 This is the oversize filter for the XJ. the 1085 is the standard filter. They both fit. the 1515 gives your more filter or more capacity.

I get them from Amazon in a 12 pack.

Now would probably be a good time to point out the Renix non-HO engine uses a different filter. It has a metric thread, and things can get ugly if you thread on the wrong filter, as it might not stay on.

You should keep your eye out at Napa to see if they ever run their Gold filter sale again.
Seems like they haven't in awhile though. When they do even I stock up.
When they do have the sale I can buy a 1085 cheaper as a regular customer then I can with my discount.
I think it is a half price sale and I want to say I pay under $4 for a 1085.
Since you buy in bulk you could buy the 1515MP. Stands for Master Pack. Guessing it comes 12 to a case.
The only difference between a 1515 and a 1515MP at Napa is that with the 1515MP there is no packaging.
If you bought a case of the 1515MP it would just be loose filters in a box.
Same goes for the 1085. There is also a 1085MP. For any of you guys that use that filter.

^^ Absolutely!! Here's the fix:CRUISER'S MOSTLY RENIX TIPS

RENIX OIL FILTER TO SAE FILTER

JANUARY 3, 2016 CRUISER54 9 COMMENTSTired of having a poor selection of oil filters for your Renix Jeep? Limited availabilty a pain for you? 20mm threads? We don’t need mumblemeter threads on our oil filters.

Here’s a simple mod that allows you to use the very popular SAE threaded oil filters which are more readily available. The old standard 3/4″ SAE thread.

You can purchase a new oil filter nipple from the dealer for under $10 and never be bothered again. Part number 53007563AB. It’s the one on the left.

Or, grab one off a 91 and later XJ at the junkyard. Be forewarned though. You need a 7/8 wrench to remove a Renix nipple, but a 15/16 wrench for the later style.

And just in case you need to replace your oil filter adapter o-rings, here’s a handy guide.
