Kawasaki Ninja 300 fuel?

Wrong as a 300 is tuned for 91 and earlier detonation

Wrong because the 300 won't make the most of the high octane, you'll get carbon build up because you're not getting the right combustion temps because half your combustion is happening in your exhaust.

i'll start and finish with: wrong, because science,
and leave you to enlighten yourself

Can't agree sorry. And the dyno doesn't lie.

A Ninja 300 is tuned for low octane, so use 91. Using higher octane will delay combustion and reduce power and efficiency on an engine tuned for low octane. So using high octane in a 300 will cost you more, reduce efficiency, and cause more carbon build up over time.

No no no, don't listen to this guy. It's not practically relevant.

Just do this:

Helpful answers in here for a new rider asking a legitimate question huh. 91 is crap fuel in not only my opinion but from people within the petroleum industry I've spoken to, however it will be fine in your bike. 95 is a better choice however a little more expensive. Either option should be fine, run a few tanks of 91 then 95 and compare the km's you get from each tank.

Too late, the original poster was clearly confused, and just played it safe and used diesel instead.
