I bought my first wrangler, 2004 Rubicon, a couple of months ago. Today I went to do my first oil change and purchased the oil filter listed in the book/fram website for the 4.0L, model PH16 to be exact. Luckily I checked before draining the oil, it looked like I bought incorrect filter. It had in it a PRIME POF195, which is equivalent to fram PH3600. After checking it out, it looks like this filter was used on the Jeep Liberty 3.7L engine. What is going on here? Do I have a 3.7L in my wrangler when the sticker under the hood says the 4.0L?
Thanks for anyone that can shed some light on this for me!
