My oil change adventure!

[MJRemi]

I decided to change the oil so off to Walmart. Out of Rotella. Wary about switching to synthetic after reading a few forums. Remembered reading store brand Super Tech is good quality, so I bought the 10w30. Looked up the filters in the hanging catalog and Jeep only went to '92 so i got the one for '92 MJ/XJ.

Before going to get supplies I wanted to drain the oil and remove the filter to compare. The plug was on so tight it took about 20 minutes of wrenching to loosen and thankfully did not strip the bolt. :fs1: Oh, and when I attempted to place the metal filter wrench onto the filter, it touched the starter and I got to watch the fireworks display 12" above my face. " Why" you ask, "is this idiot removing the filter from below and not above"? Because the oil pressure sensor and the charcoal canister are placed just close enough to prevent use of the filter wrench. :wall:

I then disconnect the battery and remove the oil sensor and, from above, remove the filter which has no size indication what-so-ever. (Champ brand) Hence, the buying of the '92 filter at Walmart.

Back home with the goods. Installed drain plug to the proper torque and of course could not thread the filter onto the threaded rod. Looked at the new Mopar filter next to the old Champ filter and couldn't tell any difference. I drove to Autozone with the Champ part number and also took the Mopar. After discussing the dilema with the 19 year old girl expert, I left with the 20mm size Bosch filter and completed my oil change with no further delays.

Thank you for letting me vent and if you don't want to read this entire rant, please stop after the first couple lines.

I ran into this problem a few weeks ago. The Mopar 090 filter will not thread onto the renix filter housing but is the correct filter for the H.O 4.0. Which filter did you end up buying?

My local napa store only stocks 2 filters for a renix 4.0, a cheap one and a better one. Last time I needed to change my oil, they were out! ?? Guess thats why they went all out and stock 2 now

Yep, the Renix uses a metric (19mm I believe, but I guess it could be 20) thread while the HO uses Imperial 3/4" thread. Otherwise the filters are the same.

 

I never buy my filter at Walmart though, as they only sell the POS Fram around here. I use Purolater Pur-One from Advance.

I got the 20mm Bosch. The other choices were Fram :no: , STP :dunno: , and Bosch.

STP :dunno: Don't they sell those at the dollar store too? :rotf:
