Quality of Oil Filters

[T_Diesel]

This has probably been covered before, but I did a search and returned SFA.

I got my car serviced last week and supplied an oil filter because i've got 8 of them at home.

When I picked my car up the mechanic said that I should really be using genuine filters rather than the ryco ones as they aren't as good.

I was of the impression that the ryco filters were same as geniune.

Is this the case, or should I be using genuine filters?

[Zeyphly]

this might sound silly but i only like to run filters that come with the little plastic cover over the end of the filter.

[bender4865]

Was it a dealership mechanic? That seems to make a big difference.

Also: Queue Isuzurover answer He knows what he's on about.

there was a thread a while ago with a very good writeup on this.

Had photos of all sorts of filters cut in half, from memory, the OEM toyota filters had much more filter material than any aftermarket. Which should translate into a better filter.

No idea what OEM nissans etc are like.

I use genurine Nissan ones.. never been a problem for me....

probably appropriate for a Pootrol


From memory, Ryco are not all they are cracked up to be. I have also seen cut-aways of aftermarket filters.

Donaldson are a supposed to be a good replacement for genuine filters.

[dogbreath_48]

I think the genuine 1hd-t filters are a bypass design, the ryco
replacment is a full flow type which obviously won't filter down the the same fineness of the genuine. Pretty dodgy.

From memory the price difference between the z161x and genuine was only 30% - not worth taking chances on a 6-7k engine IMO.

There is a bad batch of rycos atm coming from one country, they allow you to swap for free as you bloody well should.

[T_Diesel]

That's not what I asked

More to the point why do you use genuine Nissan ones over say Ryco or any other brand?

Where do you get em from?
How much do you pay for em?

Out of Indonesia, they had a faulty rubber seal that would weep/leak

Yep, and be careful when changing oil filters that the seal comes off with the filter, i.e. doesn't remain stuck to your engine.

I had a couple recently that stuck and ended up spurting farkin' oil all over the engine bay and on the ground Prolly not such an issue in bigger vehicles where you can see what you're doing, but a ROYAL PITA when you're doing filter changes by touch

In your article you mention about using Z9 filters, are these interchangeable onto a 1HZ/1HD? What is the Ryco and Toyota Filter that fits onto a 1HZ/1HD? I am assuming they are all interchangeable.

[bogged]

they arent that much more expensive than generic crap... always found them to work, why change? I tried another brand once, began with Coopers, and it took for ever for the oil pressure to build up.. so they made peace with the fishes.

Where do you get em from?

nissan

How much do you pay for em?

cant say, but it aint retail

They screw on I'm told, but they lack the second element - so full flow filtration only.

OK for petrol I guess, not so good for diesel.

The second element is the fine filter, only flows about 10% of a full flow, but steadily "scrubs" the oil.

[hulsty]

Cool so if I try a Ryco 1HZ filter it should do a better job then the Z9's I currently use, which is on a 13BT

[hulsty]

They dont interchange, completely different according to Ryco Site. Atleast all my cars use the same filter!

I didn't say they where "interchangeable"

I said the threads were the same, the seals the same, and the external size the same.
And I might be wrong too, but I did check it some four years ago and I have spoken to ppl who do it to save money (false economy?)

Oh - and I don't know if they would flow the same. Z9 might flow a lot more.

i think 1hz 92 model is z334 ryco filter. i been using a filter called sakura on me cruiser we use them at work also seem to be pretty good and are half the price of ryco

[ferrit]

i'll have to get stuck into some filters i have at the moment- got a Ryco, Donaldson and now a toyota genuine (all used) sitting on the bench.

The Donaldson easily has twice the filtration material of the Ryco, and the toyota i suspect more again- its very visible on the pressure gauge too- Ryco barely makes it to the minimum hash at full noise, Donaldson is bout halfway, and toyota is right up at the top end.

Your pressure gauge would be after your filter normally.

That means high pressure = high flow
High flow may mean less filtration (more open)
So, it all depends on your point of view I guess.

I ran some donaldson filters once. Took forever for the oil light to go out. As in long enough to consider switching off the engine and seeing what was wrong.
I went back to Ryco and the problem went away, I suspect it was a drain-back valve problem with one or both of the donaldsons.

My engine has seperate full flow and bypass filters. So a little different to you guys.

[ludacris]

For what I read to be safe and to get quility sticking to genuine oil filters is best. Also by what I read change oil filters every 5000 and oil every 10000 is safe but I think I might change both every 5000.

By the way what oil are people using in there 4.2 TD Patrols. And how much are you paying.

i use 15w 40 repco diesel oil because it is made by penrite but its 15 dollars cheaper then it is in a penrite bottle. but castrol gtx diesel oil is good probly around 30-40 dollars for 5 litres

Castrol diesel oil and fleet guard filters, fleet guard is used by cummins & mack on their truck engines, they wouldnt use them if they were crap
can get them from truck parts shops for $8.90 each for td42

Ryco Z334 = LF3608

and its a combo full flow/bypass filter rather than full flow only

[ISUZUROVER]

Donaldson, MANN+HUMMEL (MANN FILTER) and FLEETGUARD (Cummins Filtration) are the three largest automotive filter manufacturers in the world.

AFAIK they all guarantee that their filters will have OEM performance or better, and chances are one of those 3 makes your OEM filter.

Ryco are largely unknown outside Australia. Apart from a few holdens and fords, I doubt they would make any other OEM filters. The specs I have seen are nothing special.

[MightyMouse]

Several years ago...... we had to section every "Z9" equivalent filter that was commercially available for visual analysis ( engineering analysis was also done ..... ). We also did multiples of the same brand from different sources and "vintages" to try and gauge consistency - in the end around 200 odd filters.

Cutting to the chase..... there were HUGE variations in construction, quality and filtering media - with a "you get what you pay for" general trend. There was also significant differences between a manufacturers Z9 previously made locally and one now obviously sourced O/S.

We also did fuel filters ( EFI petrol ) and here the trend was even more pronounced - to the point of wondering just why you would bother with some of the real cheapies.

So its not just a brand thing - changes in quality can come about due to offshore manufacturing...... as if it wasn't hard enough already !

There are no filters manufactured on-shore (in AU) any more.

Many of the big filter companies engage in "product sharing" - i.e. manufacture products for others - when it is not economical for them to manufacture their own version of the filter - because they want to be able to offer a complete range. However if you stick to the big names with good reputations chances are the rebadged product will still be OEM quality.

How did you test the filter media MM?

[MightyMouse]

I didn't... my role was simply to arrange the sectioning.

So i got a huge box of sectioned filters back and spent some time doing the visual inspection and taking notes. They then went off to others who did the "real work".

When i followed up "the generally get what you pay for" feedback was proivided.
