I'd be very surprised if a Haynes for the 4-cylinder (and that's the only one I'm aware of) does say 90wt oil for the gearbox, it would be an error. Mine says engine oil as does the (green cover) Leyland Workshop Manual. PaulH. ----- Original Message ----- I have a Haynes that says 90w but my green-cover Bentley recommends the motor oils.
