First here's the linked paper...
Google Books Link...
Couple of snaps from it (cherry picked)...it's an old paper too.
Being an old paper, fuel volatility and battery performance in cold come into the ability of things to get going.
Next one is interesting, WRT the "doubling" of dynamic viscosity every 5C rule of thumb...
1980 and the 5W20 was described as being a synthetic basestock...hmmm who would that likely be ?
Go up a few pages, and there's a paper on European OEMS and THEIR take on what constitutes start-up oiling. (back in the day)
