thinking of going to Mobil 1 but...

[JonS]

I can not find the cold cranking numbers for the 5w-30. The pour point is very high at -45c. I hope the ccs numbers are much better. Any help on these numbers? I am looking for a good cold weather oil for the Minnesota winters (-30f). Otherwise i am considering Chevron 5w-30 or Amsoil XL7500.

I have used Mobil 1 in my Toyota and it has 200,000+ miles. No leaking but it did burn up fairly quickly and was expensive. Now use a dino oil but if you don't have consumption issues I would not hesitate to use Mobil 1.

The reason i would go to a "fake" synthetic is i figure it would not cause leaks as as easily as a "real" synthetic. I have 107k on my Jeep. Some of the normal weeping oil oil. Any thoughts?
