Octane Boost
Hey I use to run octane boost on my built EVO especially when running 91 octane gas, I like to run ethanol free gas and the only source is 91, I’m sure that’s fine for an M8, does anyone have any experience with adding octane to the M8.

I don't recommend it. I added some lucas octane boost to my 18 RKS last year while trying to reduce some of the ping I was getting under full throttle. I noticed it turned all my spark plugs bright orange when I went to check the color on them. I changed all 4 and filled the tank with shell 93. I'm sure my O2 sensors are orange as well. Never again.

What I do add every other tank is the Quickshot. It helps with the ethanol issues and cleans the fuel system as well, even though I run High grade all the time. https://www.amsoil.com/p/quickshot--aqs/?zo=331384
They have a free shipping deal on until the end of May...

Unless you are increasing the compression . Octane boost is a waste of time and money. 91 is all it needs. High octane does not mean better gas. Just slower to ignite . keeps engine from firing early under compression.

Not with my M8 but on my way home from Sturgis in 1996 there was a 76 gas station that had 103 octane on the pump. I filled it up and she ran like a beast. The inside of my thunderheader was white as a ghost... Must of cleaned her out good. Here in Commiefornia we have 91 octane that's as good as it gets, I wouldn't hesitate to throw in some Klotz 106 or 108 racing fuel maybe 30% fuel to 70% gas just to clean things up but wouldn't make a habit out of it.

Here’s another one to try. Been using it for a few weeks and it stopped my pinging. Runs great. Stock bike with slipons.

I carry a bottle of Octane Boost in my saddlebag for emergencies only. Sometimes you'll come across a gas station that has run out of premium or only carries regular gas. Rare but it happens.
