The wife got a new car, a Honda Civic LX which our first car with an oil life monitor. At 600 mi. the oil life monitor is at 90% which means if driving habits stay the same, we are looking at about a 6K change interval. Interestingly we were assured by the dealer to follow the OLM for changes so I guess we will. Oh yes, and they were very adamant about 5w20 oil only.
