I just took my 2018 CR-V EX in for its first oil change at 6 months/3500 miles. My Honda dealership told me it's their recommendation that all Honda owners follow a 4,000 mile/4 month service interval for oil changes. They explained that even though the Maintenance Minder recommends a much longer interval, their experience with the local driving/weather/seasonal conditions warranted that short an interval. My driving area is Western Washington State where the winters are fairly mild, as are the summers. My feeling is that they're just trying to get more service business for their dealership. Has anyone else experienced a recommendation like this from a dealer? The manual says to follow the MM, but I know from reading this forum that some folks believe in more frequent oil changes. Your opinions, please.
