    87 Octane or 91 Octane?

    I have a 2006 Seadoo sportster with the Naturally Aspirated 4-Tech. My owners manual says to run regular 87 Octane. Is it ok to run the Premium 91 Octane or will I not benefit from running the better gas? Thanks for any info...

    You can run 87 or better.... it won't make a differance if you don't have a lot of mods... I'd put 89 inher and let it rip....

    You will only benefit from higher octain if you need higher octain. The lowest you can run without detonating is going to be your fastest. Personally I might run mid grade in the winter, but dont think it would be necessary in the summer on a n/a motor.
