Re: over drive oil

["Paul Hunt" <paul.hunt1@blueyonder.co.uk>]

Can't speak for the US but in the UK at least GTX is sold in a number of 
formulations - including one for modern injection engines and one for older 
or 'conventional' engines.

The crucial point to remember is that unlike modern cars the MGB is not that 
sensitive to oil in either engine or gearbox, although I personally wouldn't 
use a modern very low viscosity synthetic in either, these *are* intended 
for modern engines.  There are synthetics for 'older' engines (Castrol make 
one under the GTX label!) but at the price I just don't see the value.

Castrol GTX in particular has changed significantly over the years and
is specifically formulated for modern engines...
