    Question about 2stroke to 4 stroke engine swap

    So I am taking last trip tomorrow with 250 ProXS 2Stroke have about 1/8th a tank of gas: Then Thurs/ Fri the 4S goes on. I usually run quickcleen and buy 100% 87 octane. Any reason thats a problem for the new engine? Ocassionally I will use ringfree but I have plenty of Quickleen now.

    Thanks for the feedback... Happy New Year

    Rig and run. Your new 4S (if it's a 250 ProXS Fourstroke) will run 87 octane and benefits from Quickare + Quickleen.
