I'm with Dave on this one. When I first got my GDI I had read Dave's idea that the mx5 gearbox was canted to the left so I searched the MX5 forum to look for the volume of oil advised by the manufacturer - it was 2 litres. The Morgan handbook states 1.5 litres. When I first got the car I decided to change the gearbox oil. I jacked up the car from the left and filled the gearbox with 2 litres. The gearchange was immediately much smoother. After its annual MOT and service I noticed that the gearbox was notchy, the mechanic had obviously checked the gearbox oil on the level and let out the surplus oil from the level plug. In future I will exdclude a gearbox oil check from the service checks.
