You may be referring to this in the Penrite FAQ:

Why can’t we use the new Enviro+ oils in place of the existing HPR range?

Enviro+ oils are low in SAPS (Sulphated Ash, Phosphorus and Sulphur), which in turn is low in zinc (zinc is a part of the same compound as phosphorus). Zinc is a very effective anti-wear agent and if it is reduced, may cause premature wear in the engine, especially if they use flat tappet cams. So, an Enviro Plus oil should not be used unless it is recommended for the application.


And here was Ricks comment about this issue:
Oils - can we set up a definitive list

I've been buying Penrite Diesel SP (now re-named Enviro + 10W-40 which is an E4/E6/E9 oil, ie. a heavy duty diesel oil, not petrol/dual rated and I hope to God it's still as robust as Diesel SP otherwise I'll have to find a new oil) for $165 which is a walk in off the street price.

I'd trust a low SAPS API CJ-4/ACEA E4/E6/E9 oil in a TD5 as they have balanced the lack of phosphorous/zinc with better/more exxy anti-wear/EP chemistrickery, but I wouldn't use a low SAPS petrol oil like that Peak oil with a unit injector engine.
There's been a few cam issues over the years with low EP oils like the ILSAC GF-4 10W-30 Mobil 1

Anyway that's why I'm comfortable in using 10w40 Enviro+ in my TD5.

Cheers

And further to that, the TD42T uses flat tappets, not rollers on the rockers as a TD5 injector has or roller lifters like a Tdi and I've never had to adjust the tappets since using that oil over the last four years and that car has done at least 120,000km in that time.
If we were going to get cam wear it would have shown up well and truly by now.

that was it!

ah yes, but dont all the ads say that the most engine damage is done during startup?

Use the wrong viscosity oil at your peril in these type of engines.

yep, there have been cases where the 4JX1 is driven in, the new mech drops the oil, puts in 10w or 15w and then the car wont start. mech is confused as all he did was a simple oil change.

And what a disasterous engine that turned out to be

the technologies in that engine were new for its day. it has its flaws
most diesels that are coming out now days have the same technology but the technology is more mature and more mechs know how to work with these engines.

too many aussie mechs are stuck in the stone age.

You have to take a lot from there with a grain of salt these days, most of the member's who really knew their stuff either don't post or post very rarely these days.

Molakule, Bruce381, TomNJ, Terry Dyson, Doug Hillary, Pablo know their stuff and Terry for one doesn't post anymore.

The tech was mature, it came from CAT under license, just as the TD5 injector tech came from MTU/Detroit Diesel.

Unusually for Isuzu I think it was detail issues, O rings, computer glitches.....
