whats the best one to use, not bothered how much it costs or are the standard ones fine to use, also what type?(viscosity)
This is what i use in the R26 and its fine, Fred at BTM recommends it as do opie oils http://www.opieoils.co.uk/p-981-fuc...w-80-synthetic-manual-transmission-fluid.aspx
I also had the gearbox oil in my 250 Cup changed recently, used Fuchs Titan Sintofluid, recommend by the very helpful Opie Oils.
