Question...can you replace the oil filter on a 7.4 liter votec engine with the crankcase full of oil...I mean without the crankcase trying to drain itself...I know you'll lose some and probably at least a quart, but not sure about the rest.
I've recently changed oil and now after reading a lot of info and some more on these forums, I not so sure I want to keep the Fram and instead, may replace it with a purlator...
Any advice on this is welcome.

The oil pan will be holding most of the oil capacity. However, you can replace the filter and not loose this amount in the pan. It will be a messy change out so wear appropriate clothes and a large diameter container under the filter area. Have your new filter ready to go on and in hand as you pull off the old one. Add 3/4 of a quart and check level on dip stick. Fill to full level. Good luck and let us know how it goes.

OK...thanks for the info...for a just in case, scenerio.
So, what do you all think of the Fram brand of filters?
I may just let it go, untill the next oil change, as long as the pressure stays up, like it has so far. I've driven about 1400 miles with this filter, since the last change and it had a fram on it before the change. I've also used them on my last coach with the 454 cu. in. and I've never really encountered a problem. It's just all the controversy that began some research on the subject.

I believe Fram has changed hands several times since Consumer Reports rated them far superior to anything else on the market - about 25 or 30 years ago I guess they have cheapened their product, but I have used a lot of them in the last 40 years with never a problem.
I believe the Purolator to be a better filter, but if it was me I'd just change to it at the next oil change like you are thinking of.

There was a study done a few years ago where each brand of oil filter was extensively tested, including disassembling to analyze quality of construction. I can't find the web site, but what I remember is that the Fram was one of the, if not THE, worst of them all, including the other brands they make them for. Purolator was ranked in the middle, and one of the best was WIX, which is also sold as the NAPA brand. I have been using the NAPA filters on all my vehicles for years without a problem.

I like the Wix 2 quart filter for the old 454s. An extra quart of oil has to help. I think the Wix number is 51794.

Seems that, wherever you look, Fram is taking a beating....except maybe for their ...tough guard brand....I wonder if they're listening.
Anyway, here's the site where I got most of my information, which seems to be an individuals independent study. You can also click back to the home page at the bottom.

The oil filter study on the internet is very dated.

Fram had a bad run of filters 30 or 35 years ago and the reputation still haunts them.

Leave the Fram filter on until your next service. There are hundreds of thousands of engine using Fram filters.

Considering filters are priced at ~$5 I'd use the factory AC filter in your choice of size.

My 8.1 is serviced by a large over the road diesel trucking company and they install either a WIX or a Napa Gold and that is fine with me.

I've used Fram as well as many others with no problem. Can anyone identify someone who's engine was damaged from using a Fram filter? I sure don't know of one! How could Fram remain in business if there filters were causing problems? I know there are better filters out there and I'm NOT pushing Fram products, I just don't believe using their filters will harm my engines.

After having problems with several aftermarket oil filters on a Toyota I owned (blowing the oil filters apart at the seams) I started using the Toyota brand filter on it and never had a problem.

Since then I buy my oil filters for my 8.1 GM at the GM dealership. The reason I buy at the dealership is because there was a scam several years ago with A/C Delco filters being counterfitted.

I pay about $5.00 for a PF454 filter.

I used to use Fram oil filters. I had a 76 Honda Civic , The Fram filter collapsed inside blocking oil flow and it threw a rod. It was an old car so I just parked it for awhile and sold it for parts. It wasn't til much later that i found what had caused the engine failure.
