Back in the Dark Ages, I had a '55 Chevy V8 that deteriorated down to 50 miles per quart as I crippled in to my folks house on a college Christmas break. I spent most of my available time that two weeks rebuilding the engine in their garage, under my father's tutelage. We got it together and I drove it the 900 miles back to school.

You didn't have to rebore it? by isellhondas

The Chevy I had was a '62 Impala SS with a 300 HP 327.
 
Beautiful car that just liked a quart of oil once in awhile.

I never had an Impala of any year. My '55 Belair needed a bench bore, but there was neither time or inclination to remove the block from the frame. I sat on the fenders and ran a hone seemingly forever (after ridge reaming, of course) to ready the cylinders for used pistons I bought at a junk yard, fitted with brand new extra-wide land area rings to take up the space. I hand fit the rings for each cylinder, as you would expect. I left the crank journals alone and replaced the babbitt in the big ends of the rods. This "parts exchange" did me good for another 25K miles, at which time the ol' engine got skunky again. I sold/junked the car to an old friend whose family owned a repair garage business.

10W-60 is a 60 weight oil, with polymers to simulate a 10 weight in cold temperatures.
 
W does not stand for weight, it stands for winter, meaning that an oil with a W is suitable for use in winter.

Ummm, no. You have it exactly backwards. 10W-60 oil is a 10 weight oil ("W" does NOT stand for winter) that is stable enough that when hot it only thins out to the viscosity of a straight 60 weight oil. There are two methods of stabilizing thin oils (take your pick, 0W-30, 0W-40, 15W-50, 10W-60... it doesn't matter). The first is to add what are generally termed "Viscosity Improvers" (VIs), and the second is to produce an oil from a fully synthetic base. Most middle of the road oils (Motorcraft 5W-20 for instance) use some synthetic PAO and some VIs to achieve the desired result.
 
FWIW, while formulations are a tightly kept secret by all manufacturers, it is believed that some oils, Mobil 1 0W-40 for instance, are formulated with such a high quality PAO base that they need no VIs to achieve their classification.

Kinda. They are two separate measurements. The "W" may as well stand for winter as it is valid only in comparison to other "W" or cold measurements. Yes, of course the oil thins when it warms up, though.

Sorry, the "W" never has and never will stand for "Winter".
 
As for your assertion that the "W" number is only good for comparison to other "W" numbers, not true either. It is as I stated before. A 10W-60 will flow like a 10W straight weight oil when cold and like a 60W straight weight oil when up to operating temperatures.
