I need to change my oil filter i run royal purple and just need to change the filter right now how much oil would i be expecting to lose?

 

a half quart maybe.

 

Why don't you drain it and put it back in

 

im lazyish

 

I agree with half a quart or so. Have you seen Royal Purple's new extended drain filters? The one for the XJ is P/N 20-253.

 

didn't even know they had filters

btw it was about half a quart

 

Isn't there a certain amount ( about 1/2 quart ) that stays up in the oil filter, and you lose this when you remove the filter.

Just did two oil changes, let the oil drain for over an hour on both, 'cause I walked away and got distracted by another job. Anyway went back and saw the oil was finished draining so I went to remove the filters. Sure glad I put a drip pan under the filter because there was a quite a bit of oil that came out of both.

If that's not normal, I got a problem!

 

Just to ask since I run RP as well what filter combo do you pair it with..? I'm a purolator pureone believer myself but love to hear others reviews..

 

Champion Labs says the Royal Purple filter is the best one they make currently.

I used to use the Purolator Pure One filters and they are great. I don't think you can do much better but I love RP all the way around so I'm using their filters in all my cars now.

 

I run fram filter but will switch to royal purple filter next time any idea what size i would need for a bigger filter?

 

Replace the filter and then check the oil, add as needed.

I run a WIX filter in my '06 WK with Royal Purple and have never had a problem. I do change the oil every 6,000 miles though.

 

In case anyone wanted to read up on the royal purple filter here's the link;

My jeep came with a fram filter. whenever i would turn the engine off i could here "glug-glug-glug-glug" damn thing was draining oil. piece of crap didnt have a drain-back valve and i was starting the engine without oil for a second. will NEVER use fram.

 

WCupp, are you running a oil that will need a extended oil change interval?? if you are changing the oil every 3k-5k miles you will be fine without using the RP specific filter.. I really believe from what I have gathered is that filter is really meant to go for 10K+ OCI's... Just some food for thought..

To answer your question though read the beginning of this thread https://www.cherokeeforum.com/f2/roy...-filter-76493/ I posted a cross reference sheet and the filter # for oversized..

 

I bought this oil filter it did not fit. Royal purples 20-253 is there a different one for a 88 xj 4.0?
