Ray is on the money with R 30 and R 40.
As an alternative option, I have used Fuchs Castorene Racing 40 in my glows and diesels. Not a cheap lubricant .. but good. It's made to mix with petrol.
It works perfectly with diesels. Throws a sediment (small white flakes) when mixed with methanol, no sweat, I just strain it out (good old Mr Funnel).
Just another option for you.
