Oil Filters - Wix vs Royal Purple

Before I do anything, I like to let the filter drain for several days. It's just easier and not nearly as messy.

I don't know how anyone else does the cutting open part, but I like to clamp the cutter in the vise. Then spin the filter with both hands.

Notice how Royal Purple (RP) puts a silicone seal verses Wix's metal-to-metal seal. The spring at the bottom is different, but as long as it does not fail and I don't see there being any performance difference.

The RP filter does cost more, $4.25 more than the Wix.

looks like the pictures you posted show that the WIX FILTER has a whole lot more pleats,
and that usually indicates more filter medium surface area.
more surface area, generally would allow the filter to continue to filter oil flow longer before it will become restrictive to oil flow from debris clogging it, up.
If your reading this thread and don,t have one, you need one of these tools, ID get one of your old oil filters opened up and inspected,
and ID darn sure be using several magnets to trap loose metallic crud,
is there any chance you or the machine shop, failed to clean the oil pan or block completely and thoroughly?
the metallic debris might be left over debris from the previous engine if the parts used were not correctly cleaned before reassembly!

Id also suggest anyone serious about engine maintenance buy a oil filter cutter to inspect the filter medium after oil changes for indications of bearing failure/wear issues
I see them on amazon prime for under $40 part number 66490

If you have a cam or lifter , or rocker arm , fail, its going to rapidly cause a constant steam of metallic micro trash to enter the oil flowing through the engine, its only a mater of time before that metallic trash causes other moving component wear issues
this is one reason changing oil filters, rather frequently (at least every 7-8K miles)
(IDEALLY the long versions with extra surface area)
and having previously installed several high temp magnets in an engine, you build,
is rather critical too preventing similar damage in any future engine builds

many guys use a stainless steel strainer with a magnet in the bottom to catch oil as it drains to locate engine trash in the oil,

Pop a hole in the end to let it drain.

More surface area is certainly one of the most important aspects of any filter. The RP filter has a better filter media according to RP, see the links above or below or does Wix with more surface media produce a better product???

You can't go wrong with either filter, they both have their + or - for you to ponder ............

Bottom line ........ stick with a filter that has superior construction and media like the RP filter or Wix filter. Can't go wrong withe either one of these filters.

Wix does have a better filter media material, according to them, it's called "Wix XP"

Ive used the extended length WIX filters for decades with good results
you generally have to look up the number or ask the parts counter guys,
to look up the longer length version filter numbers,
but Ive always felt it was worth the time to get the longer filter,
and minimal extra cost to use them
Id also suggest you install a long higher capacity oil filter if you have the clearance to do so, as both the extra oil capacity and the fact that the larger oil filter with its greater surface area constantly exposed to outside air flow, (especially if you have an oil filter finned cooler) can in many cases reduce oil temps 5 degrees or more

MMO is NOT an oil additive!, its simply a rather thin viscosity, high quality, automotive and machine oil,
with a high level of sludge solvent, and friction reducing additives.
that works well at breaking down and holding in suspension micro contaminants ,
so the oil filter can trap and hold them.
its not a miracle cure for anything but it certainly helps keep engine parts cleaner,
and its well documented to help free up sticky moving parts over time

clip on a decent magnet to the base of a long oil filter helps it trap metalic trash more effectively, and while $29 may sound high its good extra insurance that potentially reduces the chances of metalic debis from getting to the bearings and valve train.
consider the cost of bearing replacement?

change the oil, and filter, and slap a big magnet on the base of the oil filter

Been using WIX for years but I like that RP, might try them. If you ever want a good laugh open a Fram.
