Can you run 87 octane in a pinch on my summit xp?I have always used 91 oct so far. Will it just hurt performance running 87 or will it be hard on engine as well?
I built the engine up on my old thundercat(quad) and i needed to run 91+ after. I thought using octane boosters would work for when i couldnt get to a premium pump and i found out really fast on lots of different forums and right ups that this will not work. When a bottle says it will up your octane rating 2 points this means it will go from 87 to 87.2. There is only a hand full of octane boosters out that you can use to get your reg 87 to 91. There is a company in the states that makes some and its very very pricey. People that buy all these store bought octane enhancers and use it religously are really throwing there money down the drain. I really researched these store bought octane enhancers allot.
