What looks like dirty oil, may not actually be dirty oil; only way to really tell is to have it analyzed.
In regard to the service manager, he or she makes bonuses on oil changes, so yes, they will say the computer is not reliable. In fact, the dealers were extremely upset when this system was developed, it cut into their shop profits. Then on the other hand, the salesman is trying to sell cars.
Except for the first oil change, I would go with the computer. It is programmed to know the wear cycle of the oil, how the additives breakdown, etc.
Only thing I would watch out for is if you use an oil/foam type filter that allows in more dirt than a paper filter.
