There was a lot of discussion about this over on the VW diesel forum way back. In a nut shell the thinking was that diesel today is a lot thinner than diesel of the 70's when the pump was engineered. So now clearances are too large (especially on a pump with X00,000 miles on it). And now almost all the sulfur has been removed which was good for lubricity in the pump and injectors.
I don't have a Toyota diesel but VW and Mercedes and yes I do this. The oil is meant to be burned so there is zero ash content. There's no downside (except cost) but the upside is questionable. I don't drive many miles (especially on these cars) so what the hell. It can't hurt and may extend the life of the pump and injectors.
Some guys add automatic transmission fluid but this is tinted red and may get you in trouble, and ATF is not meant to be burned so you never know there.

EDIT - I see you're in Oz and I don't know if they have been as aggressive there removing the sulfur from the fuel. It might factor into your decision.

Many Powerstroke owners in the US (the older IH versions - 7.3 and 6.0 in Ford trucks) run 2 cycle mixing oil in their trucks. I do this in mine - 1 pint in 23 gallons. It adds lubricity for the HEUI injectors, and adds heat value to the fuel. I would not add oil to any very recent diesel trucks, as the emissions equipment on those trucks may not like the result. DEF systems are already a pain and relatively unreliable.
Diesel used to have 500ppm sulfur as a lubricant for the injector pump. USLD has no more than 15ppm sulfur, and some older pumps can suffer wear as a result. Do diesel pumps in Australia say 'ULSD' on them? Exactly what are you hoping to accomplish by adding oil - more power, mileage, longer injector pump life, more smoke?

Not 2 stroke in my case but used to put tranny fluid in my GM 6.2 Suburban. Theory was the fuel did not provide enough lubricity. Our gas stations switch to #1 oil in the winter as #2 will gell up. Probably not an issue in Oz though.

I use 2 stroke, 4 stroke, sunflower oil, petroleum and fuel filter base looks like this so the oil floats on the fuel:
the filter sawn open, used 30.000 km :

Where on my pump would i see that ULSD, and i just read that it can give you a little power and motor runs a litte quiter.

Since we went down to 500ppm I start with the 2 stroke oil in my 2 diesels .. every single tank

How much oil do you put in mer litre?
Look for TC-W3 rating.

Sorry, i think that is wrong. TC-W3 is for cool running marine engines. You want jaso FC.
Up here 2 stroke oil typically comes in an 8 ounce/.25 liter bottle. So I think most guys just dump one of these in per full tank.

Cheers mate
Looks like Shell in AU produces diesel with 10ppm Sulfur: Low Sulphur Diesel from Shell
A ULSD sticker (in the US) looks like this.

In Europe 
it is 3 ppm with the intention and deliberate political decision that ""older diesels (pumps) would destroy itself" but the 7% bio addition makes it ok I think?
My HJ is driving really sweet and quiet on 70%sunflower oil (better to stay around 35%)
As far as I understand other type of lubrication have been added, and diesel fuel with a sulfur content of 50 ppm = 0.005% so I don't use a lot of oil.
