I have just clocked up 90k and stumbled upon this thread. Thanks to the OP!

I am having Honda do a full flush (the 3 times fill and drain) today (which I pay for...), but I have two questions:

1/ With no towing and doing 35,000k per year, is it reasonable to do a top up only (no flush once a year) and;

2/ Is it likely that I have done premature wear to the box and if so provided I look after it now (whether that is yearly or twice yearly etc) will it behave for the life of the motor?

Cheers and thanks
