I think there's a happy medium...don't stay below 3k and maybe don't keep it up too high either. I'm guessing if your Boxer engine stays between 3-5K RPM 90% of the time and you go no longer than six months or 7.5K miles on the same oil you should have a long lasting engine. and of course keeping the RPMs no higher than 3k before the oil temp is up too

p.s.
Advanced Auto Parts has a special sale on Castrol Syntec, 5 quarts and a K&N oil filter for $25. Pep Boys sells it for $7 each. I plan to buy four of these lots, go with Honda Civic filters and sell the four of them for $15 or whatever. They sell for $13 each without the sale. That ought cover the two Mahle Boxster filters I picked up for $20. I'm going to go with 5w40. Hasta la vista Mobil1 and short shifting.
