10W40 isn't going to take the pressures that you get in between the gears ... 10W40 is engine oil and isn't designed for gearboxes ...

Different formulation altogether and no sulphur in engine oil.
I know people have done it but anything other than BV 75W80 is a giant cockup in my experience let-alone engine oil in there..

As in Mini engine?
My first car had 948cc's and used 20W50 mineral oil .. also had RWD!
... but I'd still not stick that in a gearbox or diff!

There are plenty of cars still on the road where the manufacturer states that engine oil of 10w 30 or 10w 40 is what should be used in the gearbox.
Most cars use gearbox oil BUT some need engine oil as putting gearbox oil in actually ruins the gearbox.
You should always refer to the manufacturers recommended oil specification for the car in question, they designed & built it so they know what lubricant to stick in it.

loads of engine oil oil got MoS2 nowadays
That's molybdenum dioxide, I thought gear oil had straight sulphur in it.

that's molybdenum disulphide
That's the one. Is that used in gear oil?
I thought it was actual form of sulphur used which gives it the characteristic smell.

yes, so as in some of the engine oil and CV joint grease
commerical grade molybdenum disulphide always contaminate with elemental sulfur.

So, can you make lysergic acid diethylamide if I send you all the stuff?
#28: Re: BE4/5 Gearbox oil sourcing troubles Author: SinfulDesignCom, Location: Ashford, KentPosted: Mon Sep 03, 2012 5:11 pm ---- Jesus - what have I done!! I only said you could use the damn stuff. Being of lower viscosity, forgetting the chemistry lesson, it will offer better performance given it will allow for free movement - imagine walking through water and then through treacle...
Maybe an issue used long term on newer boxes - but to iterate a point, look at early Saabs, Honda, Peugeots, Mini... many more - all use engine oil in the gearbox. They were fine. But adding an extra 2-3 litres of oil to each lubrication service soon became expensive. Hence a fluid which only required a change every 40-50k.
That was my point - nothing more. I will let you know how my gearbox is after a few sessions at Brands

i always though that is the only reason why people staying late night and holidays in the lab.
