    IMHO you can use any good 2 stroke oil, I have successfully. But I like to more like 32:1 ratio for air cooled bikes. I dont see how oil brand can cause a sucked gasket.

    A couple years ago I became an Ammsoil dealer for a year only to stock up on my personal supply. I bought several cases and gallons of both Interceptor and Dominator. I mix 2/3 Dominator with 1/3 Interceptor then 40:1 with VP110 fuel. I like to have some interceptor in there to prevent corrosion and lower the flashpoint. Once mixed I get only enough spooge to coat the back of the silencer and can see the red color on the fuel so not to wonder if I have put the oil in before or after I filled the fuel jugs. I've run the oil ratio as rich as 25:1 in my 125 and it may have made a tiny bit more power but you had to wring it's neck 100% of the time or it was a waste of oil. In a year or two when I run out of my Ammsoil stash I will buy only Interceptor.

    The oil didn't suck the gasket in. The mechanic was surprised to see everything coated with oil in the crankcase and wanted to know what brand of oil was I using.

    i was going to make a oil thread but then i found this one.. im picking up my new te300 this weekend and ive always ran amsoil interceptor in my bikes ( yellowcap) and ive had good results.. so i got few questions
    Dominator
    is there a difference in amsoil Dominator to interceptor? reason i run amsoil is its a great product and i can get it from my auto parts store cheap. with out having to drive 45 min to my dealer just for 15 $ a quart oil.

    and what ratio works best in these bikes. ive always ran 40:1 in my 2012 husky 300 but all my ktm buddy were running 50 to 60:1

    Great info in this thread. What about separation in cold weather? The word used to always be keep your fuel jug warm in the winter. Then a bunch of us started using snowmobile premix oil, because it protected those screamers, even in sub-freezing temps. Now happy to report I've had @ 2 gl of premix outside through our recent blizzard and bitter cold and no sign of separation :thumbsup:
    I'm using Klotz SuperTechniplate with 93 non-ethanol @ 40:1.
    :cheers:

    Yes. Interceptor is good oil. Just run this in google search:
    site:www.cafehusky.com interceptor
    Dominator and Interceptor are indeed different. Interceptor is formulated to keep your power valve clean. Dominator is a racing oil. https://www.amsoil.com/shop/by-product/motor-oil/2-stroke/

    I spoke to an Ammsoil rep on the phone and asked the differences between Dominator and Interceptor and he said they were identical in every way except Dominator could withstand slightly more pressure in extreme racing conditions. The other 2 stroke oils were better when used with oil injector applications in extreme cold conditions where the dominator might get heavy. I think this might have been a issue on the early model direct injected Ski Doo. Basically theDominator is better for the wide open pro on a MX track and the Interceptor is better for the harescramble or trail rider.

    I mix Dominator and Interceptor 50-50 so my fuel turns red and I won't question myself whether I put mix oil in the fuel, also since I use the same fuel for my 125 (which might actually need dominator) as all my other 2 strokes, including chainsaws weed trimmers and leaf blowers, I prefer to have some Dominator in the mix.

    interesting how the flash point is so variable between different oils. both of those sound low compared to most..the klotz st that we both run is 460f! which is at the other end of the spectrum..

    I know, has me wondering now. Someone else posted this here someplace:

    I use Klotz R50 at 32:1, flashpoint of 550 deg, with no spooge

    1. Motul 800 2T Factory Line "Offroad" is 485.6 degrees contain a LOT of veggie
    and coconut derivatives.
    2. Bel-Ray H1-R has a flashpoint of 435.2 degrees burns really clean on one
    aircraft motor piston test i saw.
    3. Motul 800 2T Factory Line "Road Racing" is 284 degrees.
    4. Amsoil Saber Outboard is 248 degrees.
    5. Maxima K2 has a flashpoint of 240 degrees.
    6. Amsoil Saber Professional is 237 degrees.
    7. Redline Racing Synthetic is 217.
    8. Pennzoil Multi-purpose 2 cycle oil is 212 degrees.
    9. Bel-Ray MC-1 is 208.4 degrees.
    10. Golden Spectro 2T is 205 degrees.
    11. Amsoil Dominator is 198 degrees.
    12. Spectro "Golden" SX is 196 degrees.
    13. Spectro "Platinum" SX is 191 degrees.
    14. Amsoil Interceptor is 187 degrees.
    15. Golden Spectro Injector is 178 degrees.
    16. Valvoline 2 Stroke motorcycle oil is 172 degrees.
    17. Torco GP-7 is only 74 degrees and that shit smells like soap!

    I've meant to investigate and see if some of those were celcius. I did look at amsoil to confirm it was F.

    To me what matters is not the spooge factor because thats more just a jetting issue but what they do to your powervalve.... Looking at Flash points really doesnt mean much they are all made out of different stuff

    It doesn't say that Dominator doesn't have detergents. I actually asked the rep and his exact words were that they both had the same additives except Dominator was better under extreme pressure. He cited some kind of test but I can't remember the name of it, I do remember that the difference was not that much, my guess is that it's related to the flash point. Really you can't go wrong with either oil.
