Motul makes good oil but so do many others. I would go with the grade recommended by Morgan. If they recommend 80W 140 you can't go wrong and I am sure you can find good oils in Kuwait without having to import it yourself. Find out what is available and read up what the manufacturewr says about it on the web.

I've now driven my M3W 1250 miles and 250 of them with Moroso Climbing gear lube in the BB. ( I've previously driven 27,000 miles over 10 years with the same lube in a Jag IRS rear end, so I have confidence in the product)
When I opened up the 15/16" drain port at 1001 miles and nothing what so ever came out. I left it open over night, and a few thimbles full of thick moly grease came out. I capped it, topped off the BB with fresh climbing lube, and drove 100 miles. It accepted almost the full 2 pints!
I came back with the BB still hot, and drained out the warm moly grease / climbing lube mixture, let it drain over night, and re filled with fresh Moroso climbing gear lube.
Just came back from 150 mile journey. The total BB whine is about 85% reduced! and at times almost non existent. ( around town low speed)
It used to be nearly deafening, as the whine was at a frequency that was very annoying.
Someone made the comment that the org factory lube should be used for break in / seating of the gears......I agree, just make sure you have lube in there.
To me, it makes sense that a gear lube needs more than splashing around, it needs traction / binding on the gear that is greater then centrifugal force of the gear spinning.
There are numerous brands of this type gear lube, this is simply the one I've used for 12 years on a few cars.
Be sure you have lube in your BB, and at 1000 miles or so, flush out what's in there once or twice, and try a climbing lube.
Not perfect, but 85% better.
The M3W is a joy to own and drive, highly recommended.

Yes, that was posted previously. Simply proves you can find every opinion on the Internet if you look.

Just revisiting this thread because my car is currently with a dealer to have the BB tested and then either changed or fixed.
Interesting that Rufus3 commented at the lack of oil in the box.
Having spoken to a gearbox expert who re-manufactures Ford 5 speed boxes with special ratios, he commented that the most likely reason was that the gears hadn't been honed, Quaife don't normally do this, as it is unnecessary for racing applications, and maybe it would cost more to have it done on all the Morgan Bevel Boxes, I don't know. Hence the reason that Morgan won't consider any warranty work until at least a thousand miles have passed. The lapping of the bearing surfaces is being done by the owner on the road.
As a matter of interest, I found that my noise was worst at between 65 - 80mph, lessening over 80mph. But it very definitely became worse the longer the journey, and anyway, after about 25 miles fast cruising. I guess the oil heated up and thinned down enough that it wasn't working so well on the gear teeth.
Re-reading the bits about the 'climbing' oil, I could understand that it would form a film between gear teeth, but how would it get on in lubricating the bearings, which are a much tighter tolerance? Is it too thick to get into a bearing or is that the function of the weight of it?

As you may know, my bevel box failed on my first ride out, with just 164 miles on the clock. It did sound like it had no oil inside, but there was no leak. Up until failing it was reasonably quiet.
The replacement bevel box has been fine and when I took the M3W in for first service the bevel box oil was changed. Although the M3W handbook says it is essential to replace the bevel box oil every 100,000 miles or 5 years, dealers have now been advised to change the oil at every service. In addition my drive belt was lubricated and I must admit, the car did sound a bit quieter than before its service.

What lubricant would have been used on the drive belt? [Sorry, I do remember something about this being mentioned before, but can't remember what.]
