    Mobil 1 4T 15W-50 Question

    Hello
    Can i use Mobil 1 Racing 4T 15W-50 oil for my stage 3 RXP (link below)?
    http://www.autokreso.hr/ulja/downloa...T%2015W-50.pdf


    In forums i found possitive feedback about Mobil 1 Racing 4T 10W-40 and Amsoil, but in europe we don't have this oil type. I wondering about supercharger slip. What is the difference between these two?

    I use the Amsoil 10-w40 marine. Slick stuff!! Im sure they would ship to Europe. Probably very expensive though

    Castrol 10w40

    Sorry to hijack your thread,
    I found this motorcycle oil here in Thailand,
    it s made locally by Castrol, label says it s synthetic, 10w40, 4-stroke, JASO MA2, and it costs less than 4$/quart
    Can I use it safely in my RXP (open loop)

    Any oil that is JASO MA rated will work fine in your skis..

    Sno, I guess that that 15w50 would be suited to higher tuned engine??? and 10w40 for stocker???

    Im looking for a better oil to run in my superstock, obviosly highly tuned and that Mobil 1 looks the ticket to me. R88

    Hi Guys,

    There was a concern about the use of Full Syntec Oil in modified engines. They said was something to do with slip of the cluches. I'm using 10w-40 Valvoline 4 Stroke Motocycle Oil. Its this okay for my 8800rpm application. Thanks Guys!
