Based on lots of real miles in recent years--all bikes, WalMart 10-40 house brand , cheap and works for those in N America----I have used it for around 500,000 miles on various bikes--Works great----Some samples:
I had 4 Helix, all went at least 36,000 miles each, two were traded at 50,000
Reflex---Run over @ 22,000
Kawasaki Concours---traded @ 56,000 miles
Suzuki GS500E-64,000 in 15 months.
I am aware of Japan MA and MB requirements
Two Honda CB750 Nighthawks----each traded @ 50,000 miles they were run hard, one pulled camping trailer to Alaska and back.
I continue to use WalMart oil in my new Honda NT700V.
Now, even though I ride a lot, I change oil every 2,000 miles and filter (WalMart) every other change-----I do not believe in long change intervals, based on the junk I drain out at only 2,000miles.
