Royal Purple Max-Boost (Page 1/1) Brent7088 JUL 22, 05:15 PM I went to the local auto parts store and picked up a can of that Royal Purple Max-Boost octane booster instead of of the intended fuel injector cleaner. I had planned to run through some injector cleaner using one of those pressurized non-dismantle cleaning systems at the fuel rail. How much damage would I do using the Max Boost?
