Just bought a new 2008 that comes from the factory with Mobil 1 synthetic oil. The car was manufactured and the oil put in the engine December 2007. The car now has 200 miles on it. So the oil is 1 year old. Normal interval for oil changes on my car per the manufacture is once a year or 13K miles. My question is do you guys think the Mobil 1 will be OK until I drive it for an additional year or 13K miles? The car also has a maintenance monitoring system that should of gone off in December when the dealer had the car. So I figure they just reset the monitor???
