Way back in ancient times before synthetics and motorcycle specific oils, some folks used to change the engine oil, usually Castrol GTX, every 1000 to 1500 miles. Some felt it was necessary to also replace the oil filter (if the bike was so equipped) each time theoil was replaced.
The procedure I follow has always been the same: even if I replace the oil moreoften than the factory recommends, I always install a new oil filter according to their instructions.
Since 1990 I have logged more than 500,000 miles on DR350
