Steve Swedberg discussing the importance of low volatility motor oils, and the effect of the trend toward lower viscosities.

Some really interesting points in there...
* 0W20 HDMOs under development (2.5% economy improvement);
* Merc's nano lining on cylinder walls;
* the premise that protection is going to be less about viscosity, and more about additives at the end.

I like the mention of an "old" formulation 10W40 that boiled off in tests...

I found this the other day, and found the mention of 10W40 interesting, as this could be demonstrative of light ends boiling off.

Lubrizol good and bad 10W40 pour tests.

Also, the funny thing is that as you go from say, 0W20 to 0W30 to 0W40, while the end product with VII gets thicker, the base oil cuts get thinner. I don't think that most realize that.

I got a kick out of their comments on highly volatile 10w40 oils. In the mid-70's, early-80's, that was all that my dad ran in his cars, and I ran it in my '75 Vega go-to-college car. When I bought the '85 Pontiac Sunbird Turbo, I began running 30-weights.

But that old Vega still holds my personal record for a cold start: -20F. Old carbureted POS with 10w40 oil.

The Government of Manitoba used two grades in their vehicles.
SAE 30 in the summer and 10W in the winter.
My dad had several of them mostly Ford Customs with
240 CID in-line 6's.
They always started no matter how cold it was, and
they all smelled like cigarettes.
