2009 Accord LX-P (4 cyl) with 46,500 miles. I just moved to the country, to the end of a long dirt road. Every drive begins and ends with a dusty half mile at 10 mph. Most days drive 4 or 5 miles around town. Once or twice a week, I'll log 40 or 50 mile drives at 55 mph on country roads. And every 3 or 4 months, I'll take ~1,000 mile road trips. I'm currently running Mobil 1 5w-20 with the Honda filter. I've never sent away for a UOA, but my mental maintenance minder starts pinging me around 5k miles and I have to change the oil. Any recommendations? And any tips for dirt road car care?
