I have been using auto trans oil in my 2 stroke gearbox but looking to try an engine oil.
Cheers

I use penrite... its great.

I read a few reviews and then read one by a racing car driver in the USA, who drove around Texas, on the highway and in town etc, and determined that the temp of the oil rarely varied more than a degree or 2, which (he said) meant that it retained all the correct viscosity requirements and would reduce wear. Then he also said something about how it had millions times more of some element which meant it binds to the metal better...

Anecdotally, my 1999 ZRX 1100, with motul is noisey and clunks changing gears, and I get a lot of false neutrals. With Penrite I get a more quiet engine, rarely any clunks and false neutrals or missed gears.
I will use it all the time now.. even in my mower.

Tractor transmission fluid in the 2 stroke gearbox and diesel engine oil, Delo 400 in the 4 stroke

I ran diesel oil in my little DR but it made the clutch slip a bit after a while. If it was a city only bike it wouldn't have been enough to matter.

if its the basic oils it would not be too bad, look for the Jaso approval, some of the more top end car oils have friction modifiers that don't work well with wet clutches, which can get a hard time in dirt bikes

In the US vehicles have to meet an economy standard, so rather than use a smaller more efficient vehicle like the rest of the world, they use real thin oils with friction modifiers to get their engines economical. Penrite is an Aussie company and they have no such bullshit there, so as they are saying, most of their oil should be safe in bikes. You will find this clutch slip stuff on US forums, the real world doesn't seem to have such problems.

Not really such a thing as ''diesel'' oils until you get into real diesels, most of these oils are dual rated (eg SL/CJ) and called HDEO or heavy duty engine oils, they have a robust additive package and are good for use in motorcycles. I'm using Mobil Devac MX in a couple of my bikes.

I've used HPR5 in my bikes for the last few years, with no issues.

Main reason I do it is so I can run the same oil for all of our cars & bikes, then just stock up on it when Supercheap has 25% off.

Ive used transmission oil in my cr500 and was Ok, I use tractor oil now, you want the one that is used for the gear box and motor, it has no additives and works well in a 2t. Mind you I change my oil after every ride 2hrs its a good price too.

Competitive MX bikes have some serious (and expensive) oils that are recommended. One factory rider told me a few years ago that the European KTM factory team (who are sponsored by Motorex oils) use diesel oil in their race bikes...

Ive been lookin into this myself for my exc 500, the yanks seem to rave about shell rotella which is pretty much shell rimula over here I read, also caltex dello 400 is another diesel oil thats preferred by another camp, i read another report (very scientific) that debunked the argument that you must put motorcycle specific oils in your bike.
The diesel oil is a bit cheaper plus you can buy it at any servo and not have to trek to the m/c shop all the time.

Rotella T6 is a full synthetic, 5W-40 oil that meets JASO MA. Good luck finding a Rimula oil like that in NZ.

You can get Delo 400 from the Warehouse for about $30 per 5 litres when it's on special.

Shell put Rotella through the JASO test because so many people were using it in bikes....if other oil companies bothered to do it too they might pass as well. Rimula is not the same as Rotella, but there is certainly nothing wrong with it.

So... if you had a high revving 2 stroke racing bike. Would you put a diesel oil in the gear box/clutch department??

The 2 strokes are not as high revving as the four strokes and a lot is asked of the oil(high temp and pressure) when in a combined gbox / crankcase.
From what i'm learning it would be absolutely fine in your gbox.

two strokes are much easier on transmission oil, and normally run a very simple oil in them, this is due to it only doing one job, not having to lub the top and bottom end as well like four strokes do,
