We bought a 2010 diesel sportwagen this past spring. Love it. We keep our cars forever and are used to changing the oil every 5,000 miles. I know the recommendation for this car is every 10,000 miles but when we had the first change the VW mechanic actually suggested we go every 5,000 and just pay out of pocket for the "in between" oil changes not covered by the warranty. Any thoughts about changing the oil more frequently with this particular car? With a hoped for longevity I am inclined to go for it. This is our first VW - and our first diesel! Thanks.
