I do mine at 3500 miles. Most of my miles are highway, but it can't do any harm and certainly would look good in the case of a warranty claim.

Speaking of filters, I recently replaced my cabin air filter for the first time and noticed a considerable quality difference between the japanese filter and the german made one that replaces it. At the Honda dealership I was told that it was the same filter as used in the CRV and that was the only reason they had it in stock.

Upon taking the factory one out and comparing it to the replacement upon close inspection it became evident that the origonal one was made for the Insight and the replacment conveniently just fit. The factory one had reinforcements and the pleats would go right in the seal on the plastic surrounding by just setting it in there. The CRV one you have to kind of make the first whole pleat go in to the seal around the edge. And it did not have the reinforcments.

It's not that it doesn't work, it just takes a little extra effort to ensure a proper seal on it. Something I could see a mechanic at a dealership overlooking.

My thought is that Honda would provide at the very least decent quality filters considering I'm using their oil and filters to appease them in the case of a warranty claim.
