182 Gearbox oil with plate LSD

[cattlerustler]

I am just about to fit a plate LSD into my 182 gearbox, however the oil specs say the correct oil 75w80 is not suitable for use with an LSD

What people using instead?
The builder of the diff has suggested https://www.opieoils.co.uk/p-68953-...ic-car-limited-slip-differential-oil-lsd.aspx

Will that give me issues?

Forget the diff, use the oil that works for the box.

Cheaper to rebuild the diff than to keep rebuilding the box. Plus it's a plate diff anyway, so it'll need a rebuild eventually.

Redline MTL or MT-90 is good.

Thoughts @NorthloopCup?

I used to use Redline MT-90 in my Exige and that was (I think) LSD friendly oil, the car doesn't do a lot of mileage so time between diff rebuilds will be quite a while hopefully
This now turns into is MTL or MT-90 better?

 

[JamesBryan]

Well i'm guessing it's track use mainly, so MT-90 in that case.

For a track/race car go with mt90. Lsd oil will kill a jc5 as they need gl4 oil.

As stated above, go with the oil that will look after the box, not the diff.

Thanks, just out of interest is there any benefit of running a gearbox oil cooler to protect the gearbox? I used to run one on my Exige via a laminova, it was almost essential for keeping the gearbox in one piece with sustained track use.

Ah mate, that’s like music to my ears!! Yes is the answer! I ran one on mine as well and used a laminova setup. Cooling on the Elise box will be more important the the Clio box due to its location, but it’s definitely worthwhile. If you click on my username there will be a link to the build thread. There’s a few options for cooling the box in there too. Breaking cover is the thread title. ??
