Grumpy uses a few strategic rare earth magnets inside. I always liked magnetic drain plugs myself.

One addition to this discussion. Everyone likes Napa Gold and Wix, and I concur on that. Car Quest Blue filters are also the same identical filter as the Napa Gold and Wix Gold filters. If you see them, don't hesitate to use them.

A few years back, when Advance Auto bought CarQuest, a lot of Car Quest locations either closed or switched to another franchise (some went to Napa, others went to lesser known franchises, or went completely independent), and a lot of CarQuest stuff showed up on RockAuto.com as closeout items. I bought 60 of the CarQuest Blue filters for the 51080 and 48 of the CarQuest blue 50136 for $1.25 each.

Dont forget you can order large quantity of filters from rock auto and your shipping price doesnt go up... I ordered 12 filters for my dd and only cost the $7 shipping.

Don't forget pressure drop or pressure delta which is the difference in pressure across the filter media. There are a lot of variables. Just buy a good quality, reasonably low micron filter and you'll be good. Larger surface areas dot always flow more. After partially disassembling my engine and putting it all back together...twice, I used the lowest micron filter I could find for the restart and let it run until hot. I then replaced the filter and changed the oil.

I've been working with filters for 20 years (blood not oil), all we care about is pressure drop and micron size.

A few years back I switched to the Fram Ultra series of filters. They are constructed with metal ends and have really good filter media. I use the XG5 (long) filter, but they also make them in the XG30(short). These are designed for 99%+ filter efficiency and work well with synthetic oils.

Related Question.
I ordered some WIX oil filters for SBC and they came with a warning, racing only NOT for street use.
Anybody know why this is???

leadfoot4

I believe that it's because those filters trade off flow rate for filtering ability, ASSUMING that race engines have high pressure pumps, and more importantly, get their oil changed more regularly, therefore don't need the higher filtration rate.

Adam,
The longer truck filter makes sense for a new engine break-in but after that I doubt you could justify the expense. We do not come anywhere near close to clogging up a regular filter in our well maintained toys. Why does anyone here have that much trash in their crankcase???

I have a shelf full of Wix 51069's that I got from a closeout on Ebay for peanuts. Well made and effective.

resdoggie

I don't have that much trash so I use the cheap Fram filters..............for over 40 years.

But I do find some of the views here contradictory to some extent on oil flow rate being more of a concern than filtration size. If this was a K&N air filter discussion with greater air flow rates then it would be criticized for poor particulate filtration. Same principles folks. Dirt WILL penetrate all automotive filters, oil or air. It's just a matter of how comfortable one is with particulate size. Also remember, a 100 micron sliver of metal could penetrate an oil filter. If the sliver is 10 microns wide but a 100 microns in length, it could pass through like an arrow. Finally, it would be a rare event for an oil or air filter to be the root cause in destroying an engine.

WIX / NAPA Gold. Everything from daily driver to lawnmower to performance engine.
Don't get the WIX racing, filter media is too coarse and it'll let stuff through.

If you think that the only 'work' an oil filter does is to get rid of metallic debris from engine component wear, you don't understand what the filter does. Your engine creates damaging particulates during operation. Most of what you filter out is that kind of debris. Also, cast iron engines lose particulate imbedded into the cast metal, due to cyclic heating/cooling and vibration.
Oil filters need to be replaced when the filter pores get clogged. Ideally, we would have a differential pressure gauge across the filter input/output to let us know when it requires changing. Since we don't, we err on the side of engine preservation and swap them sooner than really required.

Cast iron engine blocks are a 'dirty' material, so filter changes are required more often than for aluminum block engines.

You want to know the real reason the tall filter was used on trucks? So the s&%t-heads who maintain (or not) can go extended periods before particals finally caused a filter restriction for which you would have to replace it........there is no real added benefit on a high performance engine as the holes around the inside circumferance of the seal are the same size.....so the added filter area can never be used in a high flow sense. Not only that but nobody can use it with long tube headers.....so that answers that.

I use the WIX racing or Fram HP8.....HP4 for applications that can handle it.......I have a WIX on the 406 now because nobody in town could get me an HP8.......why do I want the Fram? The filter is super high burst and has much larger passthrough holes......Fram haters take note that they are not built with other Fram filters and their 11-12 dollar price tag reflects that.......For those with stock vehicles I do not recommend the standard Fram unit.......I go with the NAPA Gold WIX 1060.....

Baldwin filters are industrial machine filters......generally for hydraulic machines (I am an equipment troubleshooter by trade) that do not have the flow requirements that a proprietary oiling system for babbit bearing on rotating equipment......that said...they filter VERY well but I would use a standard Fram before I would use a Baldwin on a sustained high RPM engine.

Jebbysan

That is the EXACT reason.... That and the fact that most high RPM purpose built engines have whatever oiling bypass system it was designed with disabled. The filter HAS to be able to flow 100% of oil that the oil pump pumps......at 6000 rpm......this is a lot!

At the engine shop years ago.....we tried cheap Purolator filters on the dyno and that lasted about a week when we dyno'd a 900 horsepower 540 at 7000rpm and it burst.....

I have been using the Fram HP4 since I upped the rpm limit to 6300 ( since rebuilding engine from stock) on the engine. Ilike jebby says it's not you standard crap Fram.
t's a high flow high burst strength quality filter. It will allow high flow rate without bypassing.
Smaller micron filters will bypass sooner. If you don't spend much time at higher rpms or use higher wt oil or run only in hot conditions then a standard filter is probably fine.
I would rather have filtering 100% of the time with a corser medium than 85% of the time with a finer filter medium.

I am currently rebuilding my engine right now, and I bought a Fram HP4 for the break-in. I'm not sure if I made the right choice, but I based it on the rated particle size filtered.
https://www.summitracing.com/parts/frm-hp4
When I look at the information provided, the Fram HP4 filters particles at only 5 microns, when compared to WIX 51069 at 20 microns.
I know oil flow is very important after break in, so I bought the HP4 for break in, and the WIX 51069 to follow break in.

I'm curious if others base their opinions on the particle size filtered, like I did, and if there is any validity to these ratings.

Should I have bought the HP4 to follow the break in as well?

Cool....never heard of LTD.....but Hooker and Hedman no way.....

Depends where restriction is. Are the holes or filter media the restriction point?

I look at tall filters from a different perspective and that's capacity. A tall filter on a 6qt system increases capacity by 8%. That's 8% more oil to cool the engine and 8% more oil to suspend contaminates.

And the number or pleats means nothing. Its about surface area.

NewbVetteGuy

Why are mommy and daddy fighting?!? Is it oil filters again?!..


:lurk :

Not following you on this one, Jim.

Agree it's about surface area, but surface area across the filtration media, not the surface area of the outside of the filter; more pleats == more filtration media surface area if all else stays the same.
