I like to run a good oil filter so I have been using the Mobil 1 oil filters for years. For the past year the M1-203 for the 258 has not been on the selves of the auto parts stores. I could order it from Advanced Auto but found the solution surfing the net. So now I can use the same oil filter on my 258 as I do on the 4.0 in the XJ. One filter for both motors, that will be easy to remember and get.


So I went to the Jeep dealer an ordered the part #53007563 for only a little over five bucks and it was in the next day.

Here is the new oil filter adaptor and the Mobil 1 oil filter M1-204 that the 4.0 motor uses.

I used a 7/8 six point socket to remove the 258 oil filter adaptor. BE CAREFUL NOT TO LOOSE THE OIL BY PASS VALVE AND THE SPRING.

I used some petroleum jelly to hold the valve on the end of the spring.

All finished up with an off the self 4.0 oil filter, so I can change the oil when I want to instead of the next day waiting on the 258 filter to come in. Make sure to oil the gasket on the new filter before installation.

I did not check on other brands of filters for the 258 because I don't use other brands. As with everything else DO AT YOUR OWN RISK
