Mobil 1 and cold cranking specs

[JonS]

How come i can not find any cold cranking numbers for the Mobil 1 oils? Also, are the new EP oils different than the old regular M1? Anyone know the ccs numbers for 0w-30 and 5w30?

may not be published as long as it meets the API J-300 spec it is in grade most people never look at CCS numbers.

All a 5w-xx has to meet is 6600 at -30. If that is all M1 has meet, it is really no better at
-30f than dino oils. I have used M1 5w30 the last 2 years and it cranked the same at -25f than the Havoline or Castrol did.

Here's the only M1 CCS info I have in my file - it's from a Bitog 2003 Thread.

m1
10w30 crank 3848@-25° pump 10250@-30°

5w30 crank 3600@-30° pump 12700@-35°

0w30 crank 3800@-35° pump 16250@-40°

0w40 crank 4301@-35° pump 21700@-40°

Thank you. They do look more impressive than dino.
