I'm going to get an analysis done on my gearbox oil at Mainlube in Botany, Australia when I change it out.
I'll drop off the sample to them, it will take 30 minutes for the test and evaluation, from there we will make a call of what is required.
Mainlube can decant a mix on site for me.
Mainlube have a really good name with their oils, choosing oil weight and required additives here, their oil is quite expensive but they build oils for alot of raceteams, heavy plant and industry.
I only need to grab 2.5ltrs of the stuff so additional cost isn't a worry.
They build their oil packs based of the analysis, type of metals used and the use of the equipment.
I'll post up when it's done, give me a few weeks.
I think this is a different process to Blackstone, but if it's good enough for heavy industry and race teams, it's good enough for me.
