Time to replace the oil in the gearbox as I have no idea how long its been since it had a change. No idea as well as to the condition of the box as it's not the original and was replaced by the PO. Having experienced the difference synthetic oil can make to a gear change (especially when cold), I'm tempted to try it. This looks promising http://www.ebay.co.uk/itm/121635277054 as its safe with the yellow metals in the box and is GL4/5 MT1 rated. Never heard of Westway so has anyone used it with any success or otherwise?
