Svho fuel and octane booster

[marcham]

This has probably been asked every spring, so I apologize in advance but couldn't find an answer. For those who can't get 91 octane fuel, what have you found to be a good octane booster? We're planning a trip this summer where we'll have to top up from marine fuel docks that only have 89.

I am surprised to hear that some fuel docks don't have premium since most outboards (or at least all of them I am familiar with) and older PWC's use premium. Most modern engines optimized for higher octane fuels will self adjust to run on lower octane with reduced performance so you are probably fine running 89 without any booster, but I can't say that for certain.

Unless you're WOT all the time, you're fine. Otherwise, get this ACES IV Gasoline Formula « BND Automotive
