Hey guys,
I have learned a ton here over the years without starting to many threads, but I can't seem to find an answer to my question. A friend brought up this subject yesterday and I was not able to add too much to the discussion..
Anyway, why/how is there such a variance in the pour point with a given weight of oil? Is there a minimum pour point that must be met for each weight? (Is this the same as the coldest temp the weight is rated to?) He is interested in finding the 'best' oil for cold starts in very cold weather (we are in very far Upstate NY). Is the pour point the most important spec when determining this?
To me, it seems like the pour point and viscosity can be related, but not always (meaning that a thinner oil typically has a lower pour point, but not always?)
Hope this makes sense.
