well, Im wondering what the last two digits mean as well too. Like when shuld I use W30 W40 W50? like in what situations. Im sorry, just wanna learn alot more about this, I just know when to change my oil and how to LOL

I've run both a 10w30 and 10W40. I wouldn't run a W50 weight except in high heat/competition use.
