I have about done about 6-7 oil samples on my 1HD-T. When i first got it i had pennzoil i believe, i have had shell and delo. Delo is what i have been using mainly. I have also been interested in compairing figures but have never found anyone on this site that has figures to compair with for this engine. I purchase my oil sample kits from Brandtt Tractor (John Deere dealer) for $31. These can be had from Finning for arround the same$$
I ain't no oil engineer. All I know is the real world experience these last 4-5 years in Canada with 1HD-Ts (and some 1HZ's) which have lived their life on Japanese oils. If this was a Japanese oil composition vs "other" world oil composition it would stand to reason that close to "none" of the 1HD-T's coming into Canada from Japan would show any issue. In fact, there should then be no reported issues at all. Those in Canada know this is not the case. Japanese oiled 1HD-T connecting rod bearings of various mileage show the problems, and there are cases of engines calving shortly after arrival because folks did not change the bearings. Japanese spec oils are not saving these bearings from their fate.

I agree with that. It's the same in England and Australia, for what I could find out. HDJ80's that showed damaged big end bearings even after using japanese spec oil all their lives. Anyway, it seems like it helps to slow down the problem.
I think the best solution is to go with ACL bearings (based on what I read).
Anyway, if you have the choice, I think it's better to use japanese oil, there must be another benefits from that apart from the big end bearings, isn't it?

I wish we had that CRB Turbo oil here, as I said, I was refering to the GTX 15w40: Castrol España - Aceites de motor y Lubricantes - Castrol GTX 15W-40 A3/B3
I think the closest we have here to that is Castrol Tection 15W40: Tection 15W-40/B04057PBA/0701
But I don't think Tection it's synthetic like the CRB. I had never heard of a 15W-40 synthetic, it must be real good for warm climates.

Nothing beats taking a used filter and opening it up to be convinced. Look at what's inside the famous 90912-30002 Toyota filter (This picture was lifted from this excellent thread on the exploroz forum, hope it's OK, folks!):
As for cost... Well we all know how expensive they are here in Canada.... Suffice it to say I get three for the price of 1 here from my Toyota dealer in the US...
I called Western Filters today, and they recommend Mann W 940/81 for my application, and are only $11. I will be picking up 10 of them this Saturday.
We ve seen this before,and in addition to what Greg B says,its too conspiratorial for me.
I have an old diesel mechanic with 30 years of toyota experience do my pump and injector work.
He believes there is a vibration in the crank that chews out the soft early type Toyota bearings and he also says its possible that it also kills Toyota rotary pumps on the 1HZ,1HD T as they run off gears directly connected to the crank.
Other rotary pumps on 4 and 6 cyl engines last as long as the inline pumps
next winter i am switching to 5w/40 Rotella T6 synthetic.
with synth you can do double the kms from what I am told with no issues.
I was looking at other oil analysis's running 10 000kms plus with no issues on the stuff.
do you change a filter at 5000kms regardless?

That's what I've done with synthetics...change the filter halfway through. Oil analysis is really the way to find out empirically what the condition of your oil is. Money well spent.
stone what have you found out about your oil analysis's? good, bad?
The last time I did it was for my BJ74. Oil was XD3 and filter was Napa Gold 1515. Oil analysis was very good.
I'm just going through my first fill of synthetic in the 12H-T right now...still have 2k miles to go before I change the filter and send off a sample for UOA. This time it's Rotella synthetic 0W40...but I'm sure it will also still be very good at UOA.
What oils have this certification? The standard Rotella-T 15W40? The Synth 5W40? or the Synth 0W40?
I believe Rotella and Delo are the only ones...
My last pale of rotella didn't have a jaso rating.
The new one did.
From what I have read the japanese have a overly anal soot rating aka JASO MA or something.
Actually he's quite right, from a Toyota white paper I found a few years ago, it would seem the problem is caused by an acoustic harmonic developing in that engine at 2000 RPM, that sends a shock wave sufficient to cause cavitation in the bearings, which can easily explain the type of bearing damage that we've seen...
This issue has a lot to do with bearing composition. The original OEMs were aluminum based, and much more brittle than the Copper-Tin ACL bearings used for replacement.
Since reading this paper I've been avoiding letting the engine run at 2000 RPM for extended times. We'll see at 200,000 how the bearings have been doing...
Yeah, but WHAT Rotella are you talking about?
I thought it was mostly the TYPE of acid buffering used, the NA oils using magnesium, the Japanese calcium, which turns out to be better for bearings?
15W/40 Rotella T Triple Protection. Though I believe the T5 and T6 are now Jaso rated.
I have been told calcium is better...
