Best answer I have for you..................

I wouldn't call it a special oil, synthetics are more expensive than mineral oil as a base stock, and then you got all the additives. Like everything some are more expensive than others, and the good stuff is. So there's nothing really special about it, quality costs money in the oil world

And using synthetics pays off in the long run.My D2 TD5 has had synthetic engine oil all its life with 20000km service intervals.It still uses no oil between services and although the dipstick oil looks discoloured when rubbed between your fingers it leaves no black residue.Try that on a diesel that has had mineral oils thru it.

As well as lubricating its a hydraulic oil.

Hydraulic oil require a high degree of cleanliness. I couldnt find any info on the ISO4406 (cleanliness std) for LG6, but extra filtration may add to the cost of he product?

Andrew, EP oils are used in diffs with spiral bevel gears. EP has a sulphur content for the sliding friction in these types of gears. Crash boxes and diffs with straight cut gears use a straight mineral oil. Very old crash boxes from say the 1920's and earlier used a 600W oil which is about the same viscosity as SAE140. 600W was mostly used in steam engines as a cylinder oil. Crash boxes work best with SAE50 oil. Too heavy an oil and they don't shift well until thoroughly warmed up. By crash box I mean a box with sliding gears, not a non-synchro box with dog clutch engagement which the ignorant call a crash box.

What would you call a series box with straight cut crash, constant mesh and synchromesh gears all in the one box?

A pommy ****-up. Poms never could make a decent gearbox.
