We've had a '89 Accord LX (automatic)in the family since new. You are ahead of us by 100,000 miles so my advise might not be all that helpful.
We have no oil consumption issues so continue using 5W-30 as recommended by Honda.
Be sure to replace the timing belt, transmission fluid, etc., at reasonable intervals.
If the valves haven't been adjusted lately you might want to bring them into factory spec's.
