Thread: 85w/140

Hi Bruce
I put it in my series transfercase at the last oilchange,ith definately quieter.Too thick for a gearbox,unsure about the diff.

I used this to top up both my diffs in my 84 RRC, it was all I could get at the time......both diffs are leaking more than seeping 8O At least the underside won't rust....

It doesn't feel any different. I wonder if it would be OK in the transfer case? The bottle says 'thuban gear oil API GL-5' and Áutomotive hypoid diffs and final drives fitted to many trucks, off highway and earthmoving equipment'

Landies are all those things are they not [img]style_emoticons/<#EMO_DIR#>/laugh.gif[/img]

I have used it in the diffs. It is after all hypoid differential oil and is used or acceptable in most diffs. It is not what LR recommend so remember you are using it at your own risk. I have run it in my RR for 4 odd years and have used it in my Defender diffs. I would be a bit reluctant to use it in my transfer case and would definately not use it in the gearbox. The good think about it is it is available from BP in 20litre drums for about $70.

More info required. Is it an EP oil suitable for hypoid diffs?

Ron

Its Valvoline gear oil for hypoid diff GL-5. Its just a lut thicker than EP90 so I wasn't sure.

Although it couldn't be worse than the crud that came out of it ( went for a bit of a swim )


Thanks

Bruce.

It will be ok but doesn't flow well when cold. I actually run 80w140 in my Disco but I use Castrol SAF-XA synth which has much better cold flow. Rover banjo diffs are not Hypoid they are Spiral bevel and will run on GL4 as a min spec. But I doubt you'll see gl4 in anything but MTF.

I note the original question was about use in a Salisbury diff. Is that hypoid?

Ron

Pardon my ignorance, but what's the difference betweena 'banjo' type and a 'salisbury' type of diff?

What's the best type of oil for the rangie trasfer case[84 model]

yes, I'm still learning!

TIA Scott :?
