I didn't catch the 95 octane requirment in my manual, that's good stuff. The highest pump gas we can get is 94 from sunoco.

I looked this up in my manual. It says to use a Pump Octane level of 86 or higher, or a Research Octane Level of 91 or higher for a CB360.

... and isn't "today's" octane rating an average of the two? Research Octane + Motor Octane / 2?

That'd be (86 + 91) / 2 = 88.5

I'd still save the 10 cents per gallon, and go with 87! :lol:


**edit** - oops, I just Googled it - Pump Octane IS R+M/2, which would imply that you'd be good with today's 87. On the other hand, the CB360 came out in '74, when Honda surely would have known of the coming changes in fuels availability, and likely designed the engine around those availabilities. But not the older 350s, I'm thinking...

mine CL350 ran like a top on the highest octane at the pump, and felt sluggish with 87. just my gut feel, but i will run the 5 dollars a more a year in gas for the good stuff.

Like I said, the proof is in the pudding - you can't argue with results......



My butt-dyno has proven to be pretty accurate in the past.

Hi, a question about comp. testing a cold engine, I understand that this will result in about 5 psi less than a warm engine but would the same apply to an engine that hasn't run in yrs. or should I expect less? Thanks
