    I ran it in my 200 HPDI for 18 years. Still running strong when I wrecked the boat.

    Yamalube has a higher amount of moly, which has been suggested to run sooty, but if you run Ring Free the carbon should be under control. I had a same 2000 ox66 on my Skeeter.
    Pennzoil XLF supposed to be for higher hours engines, according to their rep, and they say it runs cleaner, which could be for the lack of moly. Though, Moly supposed to help with wear and corrosion, so the choice is still your.

    I used it for years as well. Way cheaper up here and ran with a lot less smoke. I had a 225 O66 which as you prolly know burned a lot of oil!

    Yea, them OX66 seem to run alot more oil, but they ran like a bear with very little issues than HPDI, which must have ran on popcorn oil the way they kept popping powerheads for a while even Series II.

    Guys at Hydrotech marine say nothing but yamalube and ringfree. That’s what I’ve been putting in mine, however, I’ve heard guys have real good luck with amsoil.

    I am following this.. My 2000 ox66 225 has always ran yamalube and ring free.


    She is a smokey, carboned up old stinker and I'd love to find an oil that doesn't make the whole prop black from a trip out
