The other thread about gas in our boats motivated me to research octane boosters. Do y'all use them in your boats and which brand is best?
Yep,seafoam and quickleenSeafoam?
Are you sure these raise the octane rating?Yep,seafoam and quickleen
Not sure if they raise the octane,but good for your fuel delivery system.Are you sure these raise the octane rating?
I agree with you there. I use Seafoam in my vehicles. Use Starbrite Star Tron in my 100% Gas applications.Not sure if they raise the octane,but good for your fuel delivery system.
Check your owners manual. Some outboards recommend not to use too high of an octane.Has anyone used Lucas octane booster or similar octane booster product? Seafoam doesn't increase octane.
Yamaha recommends 89. I have used 87 since I purchased the boat new in 21. No issues so far but wondered how it would perform with 90 octane. Lucas claims a true 3 point increase in octane level.Check your owners manual. Some outboards recommend not to use too high of an octane.
