Oil Filter Info

That bullshit 'study' has been debunked for years as 'pseudo science' on the tech groups, no need to read it or hash it out here.

I didn't expect any knowledable person to take that guys word for it, I certainly didn't. However, a person can take his lead and do a little research on their own and come up with some very valuable results.

I myself have no "dog in the fight" except trying to find the best products for my own use. Anyone that doesn't have an open mind about data that contradicts their belief system is prone to miss a lot things.

Sorry if I offended anyone, Bruce

Yep that filter study has been around all oil filters meet manufacturer design; like out autos it is preferential and makes us feel better good, bad or indifferent.

One thing we did decide and was noted in this group is that Fram filters cause dry starts in Jeep engines. They drain out overnight and allow all the passages to the valves to become empty. This makes for some unsettling noises when starting in the morning, let alone the wear factor.

I thought I damaged my '78 258 engine last summer after a hard 3000 mile run. Turns out I mistakenly used a Fram filter in the oil change after the trip which was causing the 'collapsed lifter' noises on start.

Changed the filter and all the noise went away.

Mike, that has been my experience with Fram as well. I had to change my mind due to the fact that when I started my love of machinery in

What is your recommended brand of filter to hold it's prime? My CJ sometimes sits for a couple of weeks without being started and I am paranoid of "dry starts"!

Thanks, Bruce

Fram has a bewildering array of filter price points, "Tough Guard", "Extra Guard", "Super Guard" and I don't know how many others. Maybe some of them keep their prime overnight, but who wants to risk his valve train to find out? If it sits for a long time and goes a long time between oil and filter changes, buy it something expensive like Mobil 1. Try the "weight test" if you like. If it feels heavy at least they went to the trouble to put something in there. Bosch has a good reputation and a decent middle of the road price, but I'll bet they out source their filters.

I have had mine do the "dry start" with a Wix also, but only a couple of times. So I am pretty much at a loss for finding the ultimate answer. The only one I have not ever had cause a "dry start" is the Motorcraft, but darn I hate to raise the hood and see a dang FoMoCo filter hanging on the side of my Jeep!

Thanks, Bruce

I have had my CJ7 for ten years now and normally buy the 'store brand' filter at our Canadian Tire chain store. I have a mechanical oil pressure gauge and always pay attention to cold starts and hot running for pressure and have never had any issues with those filters. They are 'white' if that matters. I sometimes find they keep the colors of the manufacturer on their store brand parts.

I was in a hurry that one day and bought the 'on sale' Fram filter without thinking.

I too used to think of Fram as quality and started working on vehicles in the 60's back when they were.

Put a shiny chrome cover on it then. :) I think PepBoys has those in the rice section.

The ultimate answer is an electric oil pump or pressure resevoir to prelube the engine prior to firing it up.

I've had good luck with either the stock DC filter (which happens when I get a low cost oil change coupon) or the Purolator Pure One when I do it myself.

And it's time to change the oil again. Gonna wait till the weather gets a bit better and check the Sunday ads for specials.

Wal_Mart's oil filters are made by Champion if I recall correctly.

My '84 Grand Wagoneer is my third one. It is about 228K miles. I use NAPA Gold oil and air filters. I haven't used a FRAM filter in years, this because I saw a cut-away display of the filters (in a NAPA store) which appeared to illustrate that the NAPA filters employed a much more dense filtration system.

I would be happy to hear of any dissenting view on this, as like everyone else here, I would just like to find the best filter and be done with it. Price is not an issue.

I can tell you on the Ford V10 the Mobil 1 filters do drain back, so I switched to Motorcraft filters and that cured the startup noise.

I use Motocrafts in both Jeeps now as well, and in the Excursion diesel, which uses a replacement-element type filter. I'd haven't done a whole lot of looking around but I'd like to find a cheaper source for those filters, they are usually 18-20 bucks apiece.

Matt

I use AC Delco oil filters. A few more dollars for the benefit of my Jeep is worth it.

They are cheaper than Fram filters to boot!

Well, just "dumb observation" on my part has told me that the Motorcraft is doing what I want it to do. I change my oil when when I can't read the "Add" mark on the dipstick, so filtration is not as critical as the "dry start" and the Motorcraft cured that problem.

As an side comment, I recently noticed that a lot of the Wix and NAPA filters are now made in China. That is the "death knell" for them in my book.

Thanks, Bruce

I did the "chop job" on a couple of MoPar filters and did not like what I found. Besides, around my world you can only get them at the dealer and they have become a little too condescending unless you are a commercial shop account. The "walk in" counter is manned by "the new guy" that is about 20 and loves "ricers". I have to resort to pointing to the part on the monitor and saying "Looks like # 17".

Sheesh...

Good Luck, Bruce

I heard that Mopar was Wix. Don't know if this is still true.
