Default zen octane?

Is it safe for the engine to use 110 octane in a stock zen?

higher octane gas burns way too slow for these realatively low compression engines... meaning that the fuel charge is still burning going out the header and not being used in the power stroke.

regular gas 87octane is preferred by the mfg but 55 octane camp fuel runs cleaner and cooler

110 - your going the wrong way For these motors lower is better. 87 is a good starting point but you can reach for camp fuel like Larry said too.

Only thing you will get for your 110 is an empty wallet and a very hot (temp not performance) motor. It would probably run worse than if running 87 to hazard a guess.

you guys are right the lower octane in the 2 stroke the better
the higher the octane in a 4 stroke the better that my 2 cents
the higher the octane the slower it burns =more heat

Mix oil with camp fuel (usual oil in same mix ratio), pour into tank, Run. No needle changes. No problems
