Looking at changing my gearbox oil and rear engine mount to the powerflex one to hopefully keep my gearbox lasting (or at least thats what im telling myself). From threads I've read previously I see I'll need around 3L of 75W80 GL5 transmission oil and FUCHS seem to be the best recommended brand. However euro car parts are currently selling the same weight Valvoline oil for £6.84 a litre so seems silly to pay more if this product is as good.
Looking for advice if anyone can help?
