Looking for the most experienced oil filter expert (or moderator) to answer one question.

That’s why I had stated earlier that I couldn’t find the flow rate of the Ford 6.2. Everything online referred to the GM with flow rates that matched closely with what the Fleetguard engineer was stating.

You could go to Melling's website and see what Melling specs for the Ford 6.2 replacement pump. Melling will most likely have one that puts out the same volume per rev as the OEM Ford pump. If you can find that, you can get a good idea of that Ford OEM pump performance.

All of which are above the Fleetguard LF16001 rated flow of 5.3gpm before going into bypass.

That seems pretty low, but did Fleedguard say what oil viscosity that corresponds to, and what that filter's bypass valve was set to?

With the Motorcraft FL820S likely being overrated at 11-13gom & the 8A sized FL1A only rated at 7-9gpm it became suspicious. The Fleetguard LF3487 (8A size) is rated at about 15gpm.

Without being able to locate accurate oil pump flow rates for the engine, it makes sense to find something that would likely give a bit of leeway

You will see filter makers making spec claims that a filter will "Flow 11-13 GPM", but they never tell you what else that spec is based on, like the oil viscosity and what limits it to "Flow 11-13 GPM". From what the Fleetguard engineering dept said, it sounds like the flow limit is based on the filter bypass valve setting.

Fleetguard never addressed bypass setting of the filter or if different viscosity oils change the rating. I did ask about the bypass setting but not about viscosity.

I’ll go check out the melling site to see what I can find. Thanks

I just Happen to Note - Inconsistencies in many Products as a Quality Assurance Inspector , as a Builder & Customizing
many Items - seems Manufacturing has taken another Nose Dive .. in last 5yrs , got really Bad about 12yrs back & Pushing for Changes
In Quality since 1985 . . When Spark Plugs only Last 18K

Certainly Price can't be or Should NOT Be - Deciding Factor . .

Here was Mellings response when I was unable to find the Ford 6.2 oil pump flow rates on their website:

Flow rates are not typically published as they can be subject to variables. Displacement or volume compared to the stock OEM pump is what is published for comparison. The 10397-BR would be standard volume, same as the OEM if you can find the OE flow rate.

Seems these engines are meant to be a secret lol

I'm surprised Melling didn't know what the OEM pump flowed per RPM vs their pump. I found the performance curves someplace on their website for the LS pumps I posted earlier. I'll dig around and see if I can find anything.

 

[ZeeOSix]

All I could find is that the Melling M397 is their OEM replacement pump with the same flow volume and pressure relief valve setting as the factory OEM pump. Couldn't find any flow performance curves on it.

The Melling 10397-BR is also the OEM flow, but has a +10 PSI pressure relief spring so it will put out more volume before going into relief. The graph I posed in post 119 shows the same pump with stages of 10 PSI higher relief springs, and how that effects the flow vs RPM. A higher relief spring setting makes the pump put more out before hitting pressure relief

But maybe you can call Melling back and ask for flow info on the M397 which is a copy of the OEM Ford oil pump for your engine.

I'd bet the oil pump on that big V8 engine puts out at least what's shown by the red curve in post 119.

I'll give it a whirl in a couple days when I'm off work. I did try Ford and they couldn't supply flow rates for their own oil pump either.

My recommendation is to go buy the Carquest Premium specified for that engine. I dropped Motorcrarft filters because of the sloppy weak glue that sheds off during use. The FL-820S is also the model that's shown the most torn media specimens, so another reason to stop using Motorcraft filters.

I’m currently running Fleetguard FL16001 (and have a box of them) so was looking into them. I’m already finishing gathering parts to add a remote spin on transmission filter (8A size) & am considering just doing the same for the engine oil filter & using matching 8A sized filters. My Bronco already uses an 8A size filter so consolidated sizes simplifies things as far as ordering is concerned.

Difficult to know what some variable displacement oil pumps put out these days, it all depends on the ECU programming.

Yes, the ECU controlled PD pumps are different animal, and it also depends on the control logic and if there's any kind of pressure sensor feedback, etc. There are all kinds of control schemes with a variable displacement PD pump. I'd rather just have an old fashioned pressure relief valve with a coil spring to control the pump's output. They work just fine. Who cares if the engine is getting more oil than it "needs". The complicated variable volume pumps are not worth it IMO to save 0.01% in fuel mileage.

Six-pack of old Fram Ultras for $25 shipped - I don't think you can beat that.

I think this might be legit, the seller only has the less popular sizes, likes the 3980 or shorter 3387 with 18mm inlet. He doesn't have the more popular 10575 or 10060 with 22mm inlet. I'm gonna get the 3980 for my 3.4 V6

i bought some XG8a’s from an ebay listing like this. @4WD has also. they all came in legit and in great shape.

Is the seller "sae-auto" or "SAE Parts"?

Yep, that's them!

For sure - they are built like Abram’s …

I ordered from this seller in the past and I did have a couple come in dented, at least one had a rattle in it.

I have bought other sizes from the same guy in the past with no issues, but I don't think he sells the other sizes that I need anymore.

 

[garageman402]

So, to be clear, these are the OG Ultras with the holes in center tube & wire screen backing? I see on the box they are the 15,000 mile item. I went ahead & ordered the XG5 for the BB 402 as well, hope they are legit OG

Not too many years ago was like 80 years ago, lol. Full flow filter use started around 1943 (Pure-Oil-Later). Does that mean people shouldn't run any oil filter now? Might as well go back to the pre-1940s if oil filtration doesn't matter.

Oil filter was an option on 1955 Chevy 265 V8, as well as a heater.
