[Mgs] 1966 OD Plug

[Barrie Robinson]

I am an engineer from good old Blighty and I know that engineers can 
be wrong.  I bought a new Maserati Biturbo and found that 2nd gear 
sucked. I heard Alfa Romeos had the same problem but had solved it by 
using ATF so I tried it.  Worked beautifully and my gearbox worked 
like a Swiss sewing machine for years.   So the engineers were wrong 
and recommend the wrong oil.  One consideration is that modern 
machinery means closer tolerances which effects any reconditioned 
engine that has had the bores, pistons, and piston rings 
done.  Another consideration is that oil, petrol, and grease have 
changed since MGBs were pups.
