I have been reading some older threads and I get the idea that low temp. (cold cranking) viscosity is a better indicator of cold weather behavior than pour point. Is that correct? I noticed that when comparing 5w30 oils, Pennzoil dino has a very low pour point of -42C but a Ccs of <[email protected] Chevron Supreme has a -36C pour point but the Ccs is [email protected] M1, a true synthetc 5w30 has a nice low [email protected] So is it the cold crank viscosity that's the true measure? Thanks.
