100 series recommended oils ?

Thats what I use in my TD
Roothy uses Penrite and swears by it and also Terrain Tamer filters.
I bought 8 oil 1 fuel an air filter and a set of belts for less than the cost of 8 genuine Toymota oil filters

Yep, Roothy just had his motor reconditioned - hardly an advert for Penrite.

I still use genuine filters for the reason suggested in this photo (you get what you pay for):

With the work its done and its age Im not surprised it needs a recondition
I notice there are no Terraintamers filters in the pic

Graham,
I don't think Terrain tamer have had their name on their filters for very long - they used to sell Sakura and another brand that escapes me. If ever you cut open a used Terrain tamer filter, it would be good to see whats inside it. I'd be pretty sure that it doesn't have the filtering capacity of the genuine filters.

I buy the Toyota filters in packs of 10. Last lot cost me $275 delivered, but there's a Toyota dealer on Ebay who was/is doing them for $300 delivered.

I have a lot of respect for Roothy - he does his job very well - he publishes entertaining articles and keeps his sponsors happy - I just have to wear my sceptics hat with some of his recommendations.

Well I put the first one in last week so when I change it will cut it up and post the pics of it They cost me about $18 ea for 6 or more

Graham,
That schematic is only a single stage filter and I expect their Z334 equivalent filter for the diesel Toyotas would be dual stage, like all five filters above. You don't know until you pull them apart.
You may want to check the blurb for the genuine Toyota filters:
http://www.toyota.com.au/parts-and-service/parts/oil-filters

Exactly what is the difference then as when u look at either of them they both have the bypass and anti drain back valves.
Probable differences in cartridge material ????


Also Ryco list two Z334's and the one for the 1HZ is apparently different to the normal Z334 being a Z334 Dual Flow

Can a normal one be used in a 1 HZ as I was going to give the couple I have to my mate who has a 1 HZ
Would have thought the plain 334's would be dual flow also similar to the Toyota ones ??????

The difference between the elements above is in the volume, quality and arrangement of the filter material. Diesel motors require higher levels of filtration - if they can filter out some of the carbon, then all the better for the life of the motor.

The dual element filter is simply two filters that sit within the same housing. The first filter is called a full-flow filter and is designed as a “first pass” filter allowing enough oil to pass through the system to lubricate the engine. The second filter is known as a by-pass
filter and has much finer screening capabilities. All of the oil eventually passes through both filters but if the full-flow filter
was used alone then the oil system would not be adequately cleaned and excessive engine wear would occur. If only the
by-pass filter was used then the oil would be exceptionally clean but the volume of oil required to lubricate the engine would
not be achieved.

Have a look at the Toyota diagram on the link (and the photo above) I gave before. The pleats on the full-flow element are quite different to increase the amount of material, so finer material can be used. The second stage element is tightly packed,(like a toilet roll), not a simple pleat like the other elements.

Thats why they cost more.
In real life, we don't see the results of poorer filtration, because it takes many years and a lot of kilometres for this to happen. But I am happy to spend an extra $12 every 6 months to remove this doubt.

Cheers
Phil

I have no idea why the Ryco website lists Z334 and Z334DF on different Toyotas. Looks like a typo to me.
