WIX 51515 for a 2000 XJ?

[dieselenthusiast]

Is the WIX 51515 the larger capacity substitute for 51085?

 

[markaboo929]

Yes it is as well as NAPA numbers.FYI a NAPA Platinum filter is a WIX 41515 synthetic media.Same as the 51515 in size.Also found out that Pep Boys has the Purolator version of synthetic filter.PSL30001

Thanks markaboo929. I had a hard time trying to verify that info.

It probably goes without saying, but don't forget when you go to a larger oil filter you need to use more oil. I started using the Purolator one mentioned and I now take an additional half quart of oil. I'm also able to go longer between oil changes. Simply thought I'd make mention of that, because undoubtedly somebody will read this and want to use a larger filter with the same capacity oil as the smaller filter.

No worries Cottontail, I know what you mean. I installed a by-pass filter on my Cummins and increased the oil capacity from a 12 quart system to a 14 quart system. There are people who think it's still a 12 quart capacity.

The BP110 filter is: 10.44" long.

Damn.. that is a big filter. You have the clean oil exiting into the valve cover?

Yes sir.

I don't really understand how running a larger filter helps. In theory there is more filtration but that is compensated by the extra oil. I have heard about pressure fluctuations with the larger filter as one disadvantage though:

Just to be clear, the picture above is a 2 micron by-pass filter. It's the second filter on the engine. In the case of the Cherokee, a larger full flow filter would increase the overall capacity. There's no harm when running a larger filter. If anything, the larger filter media would flow better.

Let us know if you see a drop in oil pressure.

 

[markaboo929]

UM....that would be a positive NO.:twak:

I use Wix 51515 and have for a few years without issue.

Run all sorts of filters, can't say as I've ever noticed a difference with one or another. I run Napa Gold or Mopar as a policy nowadays, though.

Carquest red and blue are wix filter blue being better

The cross reference for the WIX 51515 is an Amsoil EaO15. I'll be using the Amsoil filter.
