Re: HP 500 Carb Octane

So other than waisting money, there is absolutely no reason to use any other octane in stock carb 500's??

Re: HP 500 Carb Octane

Actually the 87 will make the most power and will burn the cleanest and most completely. No reason to run higher octane. Higher octane will cause more black exhaust residue on the transom.
