Is EP 90 the same/ similar as 80w 90?

Just servicing as putting gear away and manual says EP90 for topper gearboxes but I've got 80w90.

 

[Lincs Lass]

Yes it is

 

[Jackov Altraids]

Thanks.

 

[Jackov Altraids]

I've spent ages 'googling'.

Tff'ing took 4 minutes. Much appreciation for anyone that has 'looked in'.

Used to get through no end of it with a leaky chain case on an howard rotavator

I might be weird but I rather like the smell.

Yes , went in local motor factor , they said this is the gear 80w90

Nearly. I think EP90 has additives in it that will slowly eat brass, bronze etc. 80/90 doesn't. Maybe moly sulphide?

No it's not the same Someone did explain the critical differences but I can't remember exactly .
But 80/90 will suffice for those gearboxes.

AFAIK the EP means Extreme Pressure & it contains sulphur additives to increase lubricity. Trouble is that sulphur also attacks copper alloys (e.g. bronze bearings) especially in the presence of water, so some gearboxes warn against EP oils

I HATE the smell 'cos it has always meant trouble!

Wasps like it

Even worse, I only checked a gearbox when the smell stopped...... which was a bit too late

99.9% sure they dont use them type additives any more, haven't done so for quite some time now i think? but years ago you would be correct.

Your getting trouble cos your not getting to smell it when your changing good oil.. before it gets full of metal bits.

Ah I see, oil technology has seen enormous advances over the years, I just wish they could make some to smell like Castrol R
I well remember people stuffing sawdust into Transit diffs to try to decrease the whine (impossible in an early one!). I also remember advice to stuff a Bri-nylon shirt into a gearbox too, though that may have been Arthur Daley in the first Minder series!

I know of a machine dealer once told me to put sawdust in a gearbox to take out the play

The EP 90 is just a mono oil "the same thickness in winter as summer" the slightly more import thing is to check the manual to see if it's GL4 or GL5

 

[chaffcutter]

@midlandslubricants - OK now tell us the difference between GL4 and GL5, as it must be important?
