I'm planning a 5000 miles trip on my 33 000 miles drz in 2 months, mostly highway riding. I change my oil every 1500 miles but in this trip, it will be complicated.. The easiest way would be to do one at 2200 miles and the other at 2800. Some people say that doing 1500 miles in a month is harder on oil than doing a longer distance in a few days... I don't know what to do lol help!
