In a previous thread ekpolk noted that reg Mobil 1 10W-30 was thinner than it's 5W-30 sibling. While recently scanning the Mobil website I looked at the specs for M-1 10W-30 and M-1 10W-30ep. They are both thinner than their 5W-30 counterparts. I'm confused. Why are they thinner?

SAE30 grade covers a range of viscosities. As long as your product falls into that range, you can call it an Xw-30 weight. Why did XOM formulate these specific products the way they did? You would have to talk to an XOM engineer to find out. Next question.
