Fhanks for the offer but I just ordered 1litre if motul RBF600
Seems to always get good reviews though its not cheap.
I was going to go for the gulf RF800 as its alot cheaper and pretty much the same specs but if I run out while bleeding I can probably buy motul locally whereas gulf is pretty hard to get hold of and I don't want to get caught short.
I'm using an air compressor and brake bleeder to do the job which are usually quite efficient so hopefully 1 litre is enough.
If you're doing it yourself for the cost of brake fluid you might as well bleed the whole system. Better than mixing old and new fluid of different brands.
