Thread: Oil filter upgrade?

This thread has some good info http://www.aulro.com/afvb/isuzu-land...il-filter.html It's sourcing the spacer that causes the issue.

Also I read here that you need to work out what block you have and that on some the twin filters will bring no benefit. Hopefully someone can assist more....

Just a little thought.

Oil filtration is no where near as important as air filtration for extending engine life IMO, based on talking to expert oil analysts and my own testing.

Having said that, adding some sort of by-pass filtration can definitely extend oil change intervals, but you won't be adding engine life.

i have one you can have......i believe you will need to get some spacer blocks made, others will give you the details

There was a thread here somewhere with drawings and photo's.

Hey,

Thanks Rick, I am using a stock 6x6 Donaldson housing and Donaldson filters. I am happy enough with that. My concern is modern Garrett turbos (VNT) are primarily designed to use higher quality oils and of course modern filtration is better than it used to be. So I thought I might side with caution an fit the twin / bypass filter system.

Spacer, i'll have a good look about for the page with dimensions. If I find it I'll pop the link back here for reference.

Weeds, PM sent.

Cheers, Tristan

That's the thing, modern filtration in regards to oil isn't any better than it used to be.

Filter media specs used are much the same as they were forty years ago, and the Euro and Japanese engine builders tend to use higher flowing/higher nominal micron rating filters than the US car manufacturers too.

Don't get me wrong, I'm all for either a by-pass filter setup, or the use of syn medi filters (eg Donaldsons Syn-tech media and ELF filters) but they don't supply a lot of applications outside of a few modern engines either.

Don't tell anyone, but I use a genuine Nissan combo filter (by-pass and full flow in the same can) on our Patrol's TD42T and for the full flow filter I use a Donaldson P169071 or Fleetguard LF3487 which are syn media filters for a Ford (a super high efficiency/high flow equivalent to a Ryco Z9 or Motorcraft AFL-1)

Hey,

mmm, sounds like someone knows their filters!!! Thanks Rick.

I've been using Castrol RX Super since i popped the Isuzu in the 110. Can you recommend a better engine oil, one that will be more suitable for the turbo. I've read a bit of info with in this forum but nobody seams to agree on anyone product. I was planning to use Penrite HPR Diesel 15.

Cheers, Tristan

Rick - sorry I will have to (partially) disagree there.

While you are right that FF filtters haven't improved much (as they are limited by max pressure drop).

The use of bypass filters (and especially bypass centrifuges) have been shown to reduce wear, as they keep the soot concentrations lower for longer.
