...I guess that makes it right...someone reads a post on here and thinks it is fact...next thing you know it is published in books (please post the reference)
YOU really should read the link.

Anything that attracts so much vicious debate online among people you don't know, many of whom are either guessing at it or overthinking it... that's something to ignore.

Tested under numerous conditions that I've been ivolved in, my official recommendation is to simply add a squirt of KY. This will keep things well lubed even in the worst conditions, cold starts. There is no documentation or proof of a broken shaft using this method.

This is yet another well-intentioned, misinformed poster. The correct lube is NOT KY; rather, it is 0W-40 Astroglide. With Astroglide, you get superior performance, and it doesn't stain.

.I have experienced impressive performance and reliability time and time again, zero failures directly related from my recommendations
Even below freezing? Si, no problema amigos.
I would consider further studies involving 0W-40 Astroglide, but the risk of a catastrophic failure is simply not worth it, IMHO.

http://pubs.acs.org/cen/whatstuff/84/8411oil.html :
"The oil's cold-weather weight is indicated by the letter "W," meaning "winter," as in 10W, which is gauged by the oil's viscosity at 0 °F. The warm-weather weight is based on the viscosity measured at 210 °F. Oils used to be sold mostly as single-grade products, and still are for some special uses, such as extreme weather conditions or for racing cars. But the viscosity range of single-grade oils is too limited for general use. That's where multigrade oils come in."
http://www.kic-oil.com/engine-oil-bible.html :
SAE Grade counts too! The API/ACEA ratings only refer to an oil's quality. For grade, you need to look at the SAE (Society of Automotive Engineers) ratings. These describe the oil's function and viscosity standard. Viscosity means the substance and clinging properties of the lubricant. When cold, oil can become like treacle so it is important that any lube is kept as thin as possible. It's cold performance is denoted by the letter 'W', meaning 'winter'. At the other end of the scale, a scorching hot oil can be as thin as water and about as useful too.
I could post dozens more, but look it up it yourself, arrogant butthead.

Just go to the website and look. http://www.mobil.com/USA-English/Lub...il_1_0W-40.asp

I'm not getting involved in this argument, but excuse me, C&E news is not simply "a magazine" article - it is the communications arm of the American Chemical Society - it is a respected publication published by chemists for chemists. With the exception of Raudy Baum's editorial ranting it is rarely factually wrong.

Yes, and I'm a chemist by Ph.D, so you really don't want me to get involved in this considering I DO have a background that is relevant to the discussion.
time to stop the pissing match and move on.

stop wasting energy and look it up. You act like you're the only one here with advanced degrees.
How about Gulf oil Co?

"5. We have come across an oil having a 20W-40 rating. What does 'W' stand for ?
This is the common terminology used to indicate a multi-grade oil. 'W' signifies the winter rating of the oil, showing that it will perform well in cold weather. The lower the number prefixing the 'W', the lower the temperature the oil can withstand. Thus 10W- indicates a lower viscosity at low temperature than 20W-. The second figure shows the viscosity at 100 C, which is close to the bulk oil temperature in most water-cooled engines"
How about Valvoline?
http://www.valvoline.com/carcare/art...=ccr20040601ov
"Most people are familiar with oil's viscosity rating—10W40, for example. However, very few may know that the "W" refers to "winter," not "weight." And most of us have no idea what the weight-rating numbers actually mean other than that the vehicle's manufacturer specifies a particular viscosity"
Or, a book: "Polymer Characterization: Laboratory Techniques and Analysis By Nicholas P. Cheremisinoff"
http://books.google.com/books?id=LGb...Tgcg#PPA208,M1
Appendix D
The point is, the W represents the viscosity measured cold, like, in winter. This is the origin of the W designation, and frankly, is a stupid point to bring up at any rate, because it does not change the meaning of anything I said.
