Oil filter...which one?

[NoHandleBars]

Currently, I am using the Mobile 1 (Oversized) 301 filter. I've heard MANY good things about the K&N 1002, and one thing that worries me about my current one is many members reported the anti-drainback valve failing (never heard of this with K&N)

Now, here's my question...the 1002 is a MUCH smaller filter, around stock size, so how well will it filter compared to the huge 301 Mobile1 filter? Is there a downfall to using larger filter, such as loss of oil pressure?

I race my engine around quite a bit, which is why I use Royal Purple...so I just want to go with the best oil filter I can with the most flow\protection, since I'll be changing out my oil and filters VERY shortly...thanks.

[Brock]

I have only used K&N and AMSOIL in vehicles if not using oem... I know for my motorcycle K&N had both an drainback valve version and one without. You might find same for the Toyota.

Here is what I am putting on mine after the first oil change at 5000 miles

Hm, I'd love to see a comparison of this vs the K&N filter...this one LOOKS larger (might not be though). I ended up going with the K&n since everyone I asked said that they are the best if you rev your engine around quite a bit since they are designed with hi-flow and high-filtration in mind for racing...I'll check out those Amsoils though, but I can't find them locally. I also..don't get the 15k mile thing they say...I don't think I'd ever leave in an oil filter for 15k or even 10k....I'll prob be changing out the oil filter at 3k-5k....does the Amsoil one seem to be of better quality than the K&N?

[Brock]

the K&N relies on oil to catch small particals because of their more open design for high flow. the amsoil has an external microfiber that catches the small particles and then has their high flow internally. Two different ways of doing the same thing. I am sure there are more differences but that is the main thing.

you have to buy them through a local dealer or go to someones website...either AMSOILS or a dealers such as mine that is linked below.

As for oil change intervals.....oil intervals at 3k miles were based on oil and filter technology of decades ago. The synthetic does not break down and lose viscosity and cleaning properties due to heat and such like regular dino oil. BMW uses 8000 miles on my wifes car.... If you send your oil for analysis and it is not showing abnormal wear and is still lubricating and protecting against heat shear then you can go longer. By all means change it sooner if that is your comfort level...all I know is that with true synthetics and high quality filters you can go much longer. send me a pm with your email and i will send you some documents.....but in the end it is up to you.

[NoHandleBars]

Alright. Well I changed out the oil and dropped in AFE's Pro-Dry S filter inside my TRD CAI in place of the old oil filter..which I don't like. The oil that I drained, which at max has 4500 miles in it, was pretty dark....when I used RP last time with the Toyota filter I remember it still having a pretty purple tint to it...this time it was just black, so I'm thinking that M1 301 filter really isn't that great at all, and ontop of that it seemed that it didn't hold oil when I took it off (anti-drain back valve fail) so I'm glad to have the K&N in it's place. So, say I could go 5,000 to 8,000 miles using Royal Purple (even though I drive hard as hell) how often would I change the oil filter? Btw, one thing that I should say is that for the past THREE oil changes, I've been using the same gasket....the friggin' original one WON'T come out...so far no leaks, so I guess no worries, it seems as long as you don't over torque it and ruin the gasket it works fine for...well a long time.

[Brock]

the change interval is dependent on your driving style (SEVERE vs NORMAL) , the ability of the oil filter keep oil clean and then of course the ability of the oil to provide maximum viscosity while still cleaning, providing heat shear resistance, etc.

I would call Royal Purple and ask what filters they recommend with their oil...and what their change interval is for your style of driving and vehicle. I can only vouch for AMSOIL.

[DEWFPO]

A larger filter of the same brand/type like a M1-102 vs M1-301 will only hold more particles. Neither will filter any better (particle size wise) than the other.

The advantages of having a larger filter is more oil for the engine to use and more space to store carbon particles. The downside is, that when you start a cold engine, it takes a little longer for the oil to fill the larger filter (even with the anti-drain back valve.) because of the inverted design on the FJ.

Oil is supposed to get dark, it it doesn't, then it isn't carrying away the finer carbon particles in suspension. The purple in RP oil is a dye that dissipates after a short time in your engine. They even state that on their website.

I have used a stock Toyota oil filter, an M1-102, an M1-301, and now an Amsoil Ea-057 (stock sized). So far I'm liking the Ea-057 best, but time will tell.

Royal Purple, even on other vehicles I have seen, GENERALLY has still retains a slight purple tint in it when drained, and it not PITCH BLACK dark like the oil I changed today. Not to mention the fact that LAST time I used RP I went for 5,000, this time only 4,000k with the M1-301 filter. One of the things I love about the K&N is that it has a nice wrench nut at the top...easy to install\check\take off. I'm just saying, that judging by the way the oil looked LAST time, compared to THIS time, the M1-301 filter disappointed me. The oil was flat out DIRTY

[Brock]

yeah the K&N is nice for normal installation but nobody better complain about filter installation on the FJ Cruiser...it COULD NOT be any easier to get to than where it is...hahahahahaha

Lol. No it's easy, the oil change itself is SUPER easy ever since i lifted it. My only problem was with that DAMN stock Toyota filter...sand paper wouldn't get it, strap wrench wouldn't get it, I ended up having to go all over town to find the right size clamp to get the sucker off....blah! My friend had the same problem...he just stabbed it with a screw driver.

BTW, Simple Green does WONDERS for the engine bay...I used it on the pulleys to get some old mud off and on everything else...great stuff, just make sure to rinse it off well, I hear it can mess up aluminum badly if left on. However, my FJ's bay looks like it just got outta the factory ;-)

[Kokopelli]

You can always change the filter in-between oil changes too. I like the factory filter, but it is small. I'll change the filter every 2500 miles and the oil every 5000 miles. Ron

Yeah, I'll prob end up changing the filter out at 3k this time around, and then change the oil out at 6k when I change the filter out.

I upgraded to the Truefilter oil system. These things rock in so many ways it isn't funny. The stainless steel filter uses an absolute rating as opposed to an average reading for paper/synthetic. Better filtration, better for the environment, saves money, and looks sweet. I recommend it for sure. also they use their patented quadflow design to eliminate the need for a blow by valve. This means NO unfiltered oil ever reaches the engine. Tests have shown that bypass valves often open under normal operating conditions which sends huge chunks of junk into the system. PM me if you have questions or want to see pics. I love this product.

That thing does look bad ass. I've been looking into it.

[NoHandleBars]

One thing I just noticed...K&N oil filters do down to 10 microns...Amsoil only does 15...hm...also noticed the cool TruFlow filter says something that bothers me... it says "35 microns and smaller" for what it filters...I don't like when a "high performance" filter doesn't tell me how much it's filtering :-\

[Brock]

the micron rating also affects flow rate... 10-15 is standard now for most. though the difference between a 10 micron and 30 micron sounds large but physically is quite small... One thing to note is what is worse....a 15 or 20 micron filter that needs you to do an oil change possibly sooner or that requires more circulation for good cleaning.... or one with 10 micron filter that when full of particles uses bypass valve to keep engine from losing oil flow. Either way it takes good regular maintenance and checks to make sure it is working good. Once that bypass valve opens in filter...you are not filtering anything and only pumping the same dirty oil back into engine.

now that is if I understand how they work properly.... everything has a drawback if left unattended.

Hm, I don't see the K&N or stock filter having a bypass valve..so I guess it's imperative to change them out at the suggested milage. K&N's "Power Oil Filter" for ATVS and what not has a bypass valve, but not their automotive. I think the Amsoil and K&N at this time are the best filters (from the specs and the things I keep hearing) out there for the FJ right now. So I think we're both good.

[DEWFPO]

Some engines have internal bypass valves in the oil filter housing, most don't and so it's required in the filter itself.

When a filter is in bypass mode, it's really not a problem as long as it's not in bypass mode for a long periods of time. The oil is still as clean as the filter can make it and having it flow throughout the engine without going through the filter for a few minutes is not a problem at all. These engines have tight tolerances, great filtering systems and amazing computer controls. It's not like there's a bunch of 'junk' getting into the engine and floating in the oil.

Most all small equipment engines operate in crappy conditions, they're abused constantly and they don't run oil filters at all. And many don't get their oil changed for years. These engines are not self destructing or blowing clouds of oil. Look at the old VW Bug engines, no oil filter, just a screen, an those engines lasted FOREVER.

So, relax. Your at 98%, if you want 99%, then install a dual/bypass filter setup and sleep better.

my 2 cents. Tomorrow it will be worth 1.99 cents.

[Brock]

hahahaha...... I have only had individuals that wanted to make it easier to change filters or those that operate under very harsh conditions to prolong period between changes through regular filter changes instead.... Even though I can sell them I think they are overkill for our use here. my two cents.

[Toledo FJ]

The 35 micron rating on the turfilter is an absolute rating. That means that no particle larger than 35 microns can possibly pass through the filter. The micron rating on the filters you guys are talking about is an average rating. That means that particles much larger than the rated number can and do pass through the filter. A number of performance filters use the stainless steel filter media found in Trufilter and all of them have been shown to filter 35 micron and smaller particles about 90% better than paper filters while maintaining much higher flow rates. I can only tell you from my first hand experience, but I love this thing. I've had it on for three oil changes now, and I have not a single complaint.

Due to the better filtration, you can go 7500 miles between changes if you want. I still change oil every 3000 miles, but I'm anal and I want this truck to run forever.

I believe the stock filter is the only paper filter for the FJ...I was saying that it says "35 Microns" dosen't say the number that it filters down to, THAT bothers me. Lol, I just watched the Two-Road to Baja video with the FJ's, noticed the black second place winner (TRD Baja) actually used the K&N filter over the TRD one...kinda odd.

[Toledo FJ]

When I say paper, I mean paper and synthetic media.

Paper and synthetic filter quite differently...the cellulose in the K&N is known to filter FAR better than paper. So it's kinda silly to say "when I mean paper, I mean synthetic as well". I see no proof of your stainless steel mesh being more effective than cellulose, and when you say "A number of performance filters use the stainless steel filter media found in Trufilter" you do mean OIL filters right? And if so, which ones? K&N and Amsoil are both high-end oil filters, neither of them use "Stainless steel mesh" which is why I am asking what you are talking about. If these oil filters were SO much better than the high grade replacement filters, then something tells me they would be far more common in the mod\racer\off-roader market.

They seem cool, by I don't see anything that proves to me how well they filter in comparison to other filters. Saying they are better than paper filters isn't saying much, and saying they are better than synthetic...well...you have to have some pretty solid evidence to claim that. And I can't find any.

I could order it right now, but until I am 100% sure about the product and HOW well it filters, I'm avoiding it. It hasn't gotten much coverage which usually says something, the K&N and all the rest released their "Cleanable-high-flow" air filters they were all the craze....why isn't this?

They also say some serious BS on their website... "Air filters are now running 300$" where did they gather that from? I just bought a AFE Pro-Dry S filter for 55$ shipped to replace my cotton-gauze (oil) air filter in my CAI. Seems as if they are using that B.S. as a unneeded justification for the price. Then they go on to say "here are two top seeling oil filters so you can see what they look like after being used" but show no data on what filters they are, or brand...just seems sketchy, no solid data. Then again it says "LARGEST FILTERING AREA- Deep pleated, duplex woven, 30 micron, T304 stainless steel filter" it seems as if they don't go down to small microns because Truflow claims "well we studied the microns and 40-30 were the most dangerous ones in the engine" it REALLY doesn't seem like they designed the filter in mind, to filter anything below 30 effectively. As a matter of fact, the only thing they say about smaller particles than 30 is "We added a rare earth magnet to our filter to eliminate even smaller particles from entering your engine." wow, that tells me a lot.

From what I've read, I would LOVE to pit the K&N or Amsoil filter against the Truflow filter, and I would be willing to bet MONEY that they would filter better.

The ideal and the ONLY one that I have gathered information that says it is a very effective cleanble oil filter, is the Pure Power oil filter, which has won quite a few awards. If I was going with one, I'd prob go for that since they actually have TRUE tests done on their filters. Not just gibberish.
Pure Power Oil Filters High Performance Motor Oil
Their filters go all the way down to 10 microns..they have been in the field of making cleanable oil filters for FAR longer than this "tru flow" brand. Hopefully soon they'll start making some Toyota ones.

[Toledo FJ]

you are correct. That was silly of me to say. But I don't think I'm wrong about their superior filtration. Just call any of the companies that make these and ask for independent data proving superior filtration. They have it. I don't care if you buy one or not. It is your engine. I was just putting it out there. I CAN say from personal use that the trufilter is awesome. I love it and wouldn't go back to the other filters I ran (TRD, Mobile 1,K&N.

As to the other companies: Scotts, Flo, Pure Power, KTM, K&P...... I can keep going, but you get the point. Just google "Stainless steel oil filters"

I don't know what you mean about not getting much coverage: being on a winning BAJA 1000 race truck is pretty good exposure and good evidence that it works. Lots of people in the race world know about and run stainless filters. Especially motorcycle and atv guys. If you google "Trufilter oil filter" you'll get a bunch of hits including reviews. I couldn't find any that debunked their claims.

There are indeed $300 dollar air filters, so that isn't BS.

The Trufilter and Pure power filter are the same thing dude. So, why you think the Pure Power filter is so special, I don't understand. I agree it is an awesome filter, but so are all the others. They use the exact same surgical grade stainless steel filter. The claims made by both companies are essentially identical. In fact, the Trufilter has a higher burst pressure.

I think you would loose money on your bet!

But again, i have had the Trufilter on my truck for almost 10,000 miles and couldn't be happier.

Pure Power filters to 10, Truflow says NOTHING about that, where are you gathering the burst pressure on your filter? I see NOTHING on the website. Why do I think the Pure Power is special, as in better? Because a SS filter isn't a SS filter, that's like saying a Synthetic filter is a synthetic filter, which is NOT true, they are NEVER equal, there is ALWAYS a better, or worse version. PurePower has actually won awards. Just because they strapped a "Lifetime Oil Filter" on a baja racer, and raced for a day or two, and MADE it there, doesn't really mean that oil filter was good, or bad. That's a short time, not exactly enough to prove anything. I could say, oh the baja FJ used a K&N and won 2nd place in it's class, oh so it's clearly better than everything else, but that's not true. Short race, and with OIL filters you need long-term data.

Also, do you mind looking up a standard 300$ air filter? I'm having problems finding one. Even more so when they refer to the 300$ as an average price. Also, why do you think Purepower and Truflow are the same? Is it because they are BOTH ss filters? Because they have a stainless steel mesh, that makes them identical? Well then damn, guess there isn't any difference between a K&N, TRD, or Mobile1 filter! No, but really, look at the specs. They are quite different.


And what claims am I trying to debunk? All Truflow claims is that it is a cleanable air filter, that is better than paper, and can filter down to 30 microns...which isn't that impressive when other synthetic filters do 10-15. I am curious as to how you believe a filter that specifically says "filters down to 30 microns" is going to filter BETTER than one that goes down to 15 or 10, thus is able to catch far smaller particles.

Another thing to note, is neither company, has compared it's "high end oil filter" to any "high end disposables" which is silly I believe. All I keep seeing is "better than paper" which would be stock...they don't say anything about higher grade race oil filters such as TRD (which I hear is crap), K&N, or Amsoil, or even Mobile1. That is another reason I doubt they filter better than those, if they did, they would be damn sure to showcase it.

It's good that you enjoy your filter, all I'm saying is their "superior filtration" data is a joke. They compare it to a stock, crappy paper filter. They don't go into the higher grade ones when that is exactly what their filter should be competing with.
