For my 10cents worth or pence or whatever.
Running your Bella heats up the oil and crankcase gases, as it cools it draws in cool moist air. The warm/hot air in the crankcase reduces in volume as it cools and draws in moist air. This can polute the oil and it needs to be really heated up to be burnt off by going on a long run. This is one reason I feel that frequent short trips are BAD for engines and componants if the oil can't get up to normal operating temp.
Another reason is that if there are longish periods between starts the cushioning oil film on the cams and other moving parts can drain away leaving little protection at start up. Talking about weekend only driving here where Bella rests during the weekdays, this could increase the amount of metal dust held in the oil. I mean by this that an engine that travels 2000miles being started 100 times (many short trips) would probably have more wear and dirtier oil than an engine that has also done 2000miles but only started 10 times (fewer but longer trips)
Anyway thats my reason I give to her indoors when she complains that I always seem to be changing my Bella's oil. I do mine yearly and use a full synth 10W50 Penrite.
