Oil filter used and why?

[1985 CCX]

Planning an oil change. Picked a high ZDDP oil.
Looking for a good filter that minimizes psi restrictions.
Anyone have a favorite?

My mechanic likes to use Baldwin for my FE applications.

On my solid lifter FE, I've always used Moroso. There have been many threads on the oil filter issue over the last decade. Some have some pretty learned postings. I'll just copy the blurb from the Moroso page below on the flow/filtration/pressure issue. Racing Oil Filter

After many years of designing and testing racing oil systems and related components, we’ve determined what’s most important to oil filtration. Many filter manufacturers stress the importance of filtering the smallest particles out of your engine’s oil, with references to "micron ratings" of 10 or less for a filter’s efficiency.
With the help of research performed by filtration technology experts, Moroso engineers have determined that particles smaller than 20 microns in diameter are not large enough to produce engine wear. Furthermore, we’ve found that filters with extremely low micron ratings create an excessive pressure drop across the filter. They can be so restrictive that the filter by-pass valve can open. With the by-pass valve open, unknown to you—NO FILTRATION will occur!
To maximize filter performance, Moroso Racing Oil Filters have a rating of 27 microns, which produces a maximum initial restriction of only 2.5 psi when tested to SAE j806! The result is less pressure drop, more flow, less oil by-pass and maximum filtration performance important in severe racing conditions.

Well, you know what they say about opinions.....but you asked, so I'll give mine. I believe that the OEM's put a lot of R&D into designing their oil filters and they have very sophisticated resources for testing that most aftermarket manufacturers don't. OEM's also have a vested interest in producing a quality product.....they're not fond of replacing engines under warranty. For purely racing applications, some of the aftermarket choices are likely a better choice than the OEM filter, but most of us aren't racing. I personally use Motorcraft filters in my FE.
Just my two cents.

1st choice: Motorcraft FL-1A
2nd choice: Wix 51515

Both have been well-rated, but the Motorcraft has what appear to be less restrictive inlet holes in the base plate.

Just my $0.02.

I use the Motorcraft and WIX filters and have for years with no problems.

I was just recommended the Ford Racing CM-6731-FL1A.
Not cheap. Looks pretty nice. Anybody familiar with it?

Uhhh, isn't that made at the Charmin factory?

[desgros@vtlink.]

Change oil and filter often. Very cheap insurance for an expensive motor.

All we use these on FL1 applications. heavy burst proof case, the base is much thicker with deeper threads to engage the thread on the block and it has an "anti-drain back" silicone valve to keep oil in the filter (an issue depending upon how the filter is mounted). A little pricey but what's a few extra dollars for the assurance your filter will not come apart under high pressure/heat conditions. I am pretty sure Ford has determined these are the right units to use.

FL1 all the way........plus it says Ford on it.

I use MotorCraft FL1-HP because of the higher relief pressure, 22 PSI and the FL-1A is 11 - 14 psi

Motorcraft oil filters are specifically designed for Ford, Lincoln, and Mercury vehicles. Each Motorcraft oil filter, including the popular Motorcraft FL-1A, uses as many as 12 high-quality components.

Construction features include:

* Steel cases: "Ironed" for a precise fit, fluted to ease removal, and painted for rust resistance
* Pressure relief valve: When it's cold outside, or if the filters become clogged, oil flow through the filters can be reduced. If this happens, the relief valve opens to provide a continuous oil supply. Its design also minimizes the chance of contaminated oil recirculating back
* Anti-drainback valve: This feature keeps oil in the filters to prevent "dry starts" after your engine has been turned off. It's made with specially formulated materials that resist the aging effects that an engine's heat can cause
* Efficient filter media: Re-engineered media increases Motorcraft filters' dirt-collecting capabilities, allowing them to capture more engine-harming particles than ever before

AC DELCO , Long live the CHEVY oil filter in a COBRA!!!

When Tom Lucas was at my place he gave me one and said, "This is what you should be using". I was under the impression it was new. Didn't realize there were so many FL1's to choose from.

What oil did you pick?

[55312]

Wix 51515R and Brad Penn oil for the high ZDDP.

Wix 51515R has a 61 micron rating.
Wix 51515 has a 21 micron rating.

I would not use a 51515R on a street engine. The R is for racing. It flows more. It doesn't catch near as much trash as the non R version.

If I took a repainted Ford filter, put it in a fancy box with a picture of a Cobra on it and advertised it as "better" for $XX I wonder how many I'd sell? OEM is generally a good plan. Good pricing due to mass production and they care about their reputation. I really doubt small aftermarket outfits have banks of oil engineers on the payroll to crank out filters which aren't even their main products?

This is correct. Do not use a racing filter on a driver. The filtration isn't adequate. Wix will tell you not to do it as well.

I've used Wix 51515 and now I use a Baldwin 253. Baldwin and Wix both have reputations of being among the best. The Baldwin has the best combination of high flow and good filtration because the media area is higher. This filter also has a thicker canister and very strong construction, so it has high burst pressure.

Wix 51515 (not racing)
* 349 in^2
* 8-11 psi bypass valve
* anti-drainback
* 21 micron nominal
* 7-9 GPM max flow
* Burst is 290

Baldwin B253
* 490 in^2
* 20 psi bypass valve
* anti-drainback, standpipe
* 18 micron nominal (50% eff), 40 absolute (98.7% eff)
* Burst 600 psi
* Flow 12 GPM at 5 PSI. 8 GPM 4.1 PSI. 18 GPM at 14.8 PSI
