There are so many different theories about this that I don't think either is THE correct answer. With modern oils being so much better than they were, the old advice is probably dated, but you can worry too much about the correct oil change regime. If you've fitted a filter as well, that changes things too. When I finish my rebuild (shortly I hope!) I'll be doing a few miles getting it fettled, MOTd and sorted, and then am off for a weekend away on it. I'll change the oil before my trip away no matter how many miles ive done and then have a long blast on it. As long as it has some oil in it should be fine! :-)
