Does anyone know of a Motorcraft number for a larger (higher capacity) oil filter for the FL820S? Is the 821 a larger filter, it appears to be? I'd like to use a larger filter on my 6.2L

Thanks,

 

Many times a physically larger filter actually doesn't have a higher capacity for trapping dirt. Lots of other factors go into filter capacity, like type of filter media, how it is fit to the case, number and size of pleats in a pleated media, etcetera.

So, without a full breakdown of all the filter facts, that larger filter may not be any better than the original.

You can always get a remote kit that uses double filters.

 

Why would you want a bigger oil filter? Ford has spent millions on R&D on the 6.2L. A larger filter does not equal more filtration. The S means there is a silicone anti drainback valve present to eliminate dry starts.

The 820s is the most widely used oil filter in Fords lineup. I can't see a problem with it. Look at police cars, those 4.6l motors use the same filter and go 200,000-300,000 miles with little oil related issues.

 

I feel the 820s is more than up to the job. It's large compared to some of the filters I've seen other companies use on similar sized engines.

 

Ya take a look at what Chevy uses on the 6.0 gas engine. I've seen tea cups bigger.

 

I say again, you can't tell much about filter capacity by the size of the filter can. It's all in the media inside.

 

If you have a parts guy that is patient with you, maybe you can find one that is longer.

I don't buy off on the premise that these vehicles are equipped with the best of anything. It's all a compromise with the bean counters and the engineers. It all comes down to one oil filter costing .10 less than another. If the cheaper filter will work, that's what we get. That's business.

But I figure, if a 820s works for the raptor, it should be fine for our needs.

 

Awesome info. I always wondered the significance of the 'S'. Wonder what the 'FL-1A' means? On a side note, the local oil joint I frequent uses Security brand oil filters, and my 3 Liter V6 Ranger has a size '36000A'.

 

Yeah...they also spent millions developing the 6.0. Did you see how that turned out?

As long as you don't do a bunch of short trips (the oil will never get to operating temp) adding more oil capacity is always a good thing. Even if there is no extra filter media.

 

The 6.0 was not a Ford motor, it was an Internatonal design that was modified by European company to meet emissions.

How is adding more oil than recommended a good thing?

 

Oh, in that case I guess Ford didn't invest any money at all into developing the 6.0.

More oil is always good for an engine. It stays cleaner and cooler. That's why the big trucks with the 6.0 take even more oil than a Super Duty.

Just because Ford did it doesn't prove anything. Ford has done a lot of stupid things over the years.

 

No, the diesels with HEUI injecton use oil to actuate and fire the injectors. Diesels have lots more parts than a gasser needing more oil. Turbo, Injectirs and the base engine. It's not a matter of needing more oil to run cool but rather to keep everything firing.

 

I'm not sure what that has to do with anything. I know how they work. All engines will benefit from a larger oil supply. I never specified a type. I said all engines.

The only time it ever becomes an issue is if there is too much oil, it takes too long to get hot. If you only drive short trips, more oil can hurt you. Otherwise it is always beneficial.

Stop trying to argue.

 

No argument here, just trying to clarify. I can't seem to get the emoticons to work on the app.

 

Reminds me of when I put a double oil filter mount and an oil cooler on my 302 Bronco. Worked great for running around the desert in the heat of the summer. Not so good in the winter just driving to work. Slowed down the warm up process.
