MMO is great stuff, but your octane is slightly lower while running it.
I use it once in a while just to clean stuff out.

 

R-Dub - You been drinking again?? LMAO...I would've liked to seen that post

 

My old bike LOVES high octane fuel (ironhead). It runs best on 100ll aviation gas. I can tell a huge difference when running it also.

The EVO Roadking runs best with 93 right out of the pump. I can tell a difference when running the 87 in that it will knock if I accelerate too quickly at low rpms. It also runs rougher. I think it would run even better with higher octane fuel. Most high compression engines do run best with the highest stuff you can get.

 

I agree with FAAST ED. I took a ride out to the 105th in wis. I took a large bottle of lucas booster in case there was some questionable gas on the way.

 

i run 87. my bike is a stock 85 evo. it's never been apart because it never broke.

 

I keep a bottle in the saddlebag,use it when I can't get good gas out in the rural parts of the country,never had a problem with it !!!

 

Thanks almost all. One positive on boost, Hmmm. I still think I will try it for a tank and see. I will then post my results. Almost bought a bottle today but it stated it treated up to 15 gallons and I wanted to hear what you all had to say first. Guess If I do try it I will use a third of a bottle. Just filled up and a few days of crappy weather coming up so I will let you know my findings when I get results. God bless you all, regardless of what you held back or your negative responses..... God loves us all but you have to let him into your heart!!!!

 

Back when gas hit $4.00 per gallon, I switched to the cheapest gas I could get. Sheetz Reg. The bike didn't notice, and I've been running on regular gas ever since. No issues with performance, MPG, or other issues.
