quote:Actually they list their pour point as -33c, which is -27F. Their cold cranking specs are very vague too, it just says less than 6600 for each of their oils at the corresponding temperature that they qualify under.
Originally posted by Drew99GT: What are you guys talking about as fas as castrol and cold weather? I found a data sheet showing a pour point of GTX 10w-30 SJ as -33 F. Which was as good or better than all the other major brands.

Originally posted by JonS: I found that Castrol tended to varnish/sludge up engines. I have talked with people who have used it and this is what they have said. I have used it and noticed it does not clean well. Also, the pour point is -27f (not good)
