Thankyou very much Fred, with all the hype about what to and what not to use in the gearboxes that has stored confidence in it for me, good price from GSF too which is a bonus.
How often would you recommend changing it? In fact how often would you recommend changing the coolant and brake fluid too?
My 182 has done 72K and i'm damn sure only the engine oil has seen changes so £75 and some gearbox oil. eng oil, brake fluid and coolant up i'm good to go.
Cheers
