Yeah, and Toyota recommends to change the oil every 7,000 miles, but even if you change it every 3,000, the engine is still prone to sludge.
The oil life monitoring system in my G.M. vehicles has always indicated change engine oil before 6,000 miles. I don't see why oil would last more than twice as long in another make.
