Cold Weather Grease

[CurlyDave]

Actually, it should be "moderately cold weather grease".

It was about 40 degrees F today, and I greased my tractor.

The old grease I wiped off the zercs had the consistency of taffy. Really hard to get it off. The new grease was stiff and hard, but not as bad as the old grease.

Is there a low-temperature grease I should use in winter?

Dave,these folks have good products.http://www.schaefferoil.com/products.html

I use whatever general purpose, farm and truck, grease that says "all temperature" on the label but others here suggest using only "Moly"

There is always something similar to what they use on the space station!

Braycote 602EF is a smooth, buttery, gray colored NLGI #2 grease. The base fluid (Brayco 815Z) is a stable perfluorinated polyether with exceptional chemical resistance, extremely low volatility, and a wide temperature service range. The gelling agent is a tetrafluoroethylene telomer. This grease contains molybdenum disulfide. Braycote 602EF is nonflammable, does not use any chlorofluorocarbons (CFC's) during product manufacture, and is in general, chemically inert. Braycote 602 is an excellent lubricant, has good shear stability, and low acute toxicity.

As with any high performance material, being used in critical applications, one should never contemplate its use without being familiar with its typical properties.

Temperature Range:
-80ｰ C/-112ｰ F to +204ｰ C/399ｰ F

Depending on how cold it gets in the winter you could use a NGLI #1 grease instead of a NGLI #2 grease. It will pump a lot easier in cold weather. Just like oil viscositys there are multiple viscositys available for greases. Most will be available in NGLI ratings as low as #00 and some even lower. Once you get to a NGLI #00 grease you are entering the "semi fluid" range which would remind the average person of gear oil. Another thing to look at in grease specifications when you are shopping is the greases pumpability test rating. The ASTM test standard is ASTM D1092. This test gives you the lowest temp at which the grease still pumps easily out of a manual grease gun. You will find that the low temp operating range of NGLI #2 greases can varry quite a bit from brand to brand. Some will stiffen up while others will maintain their flow properties much better. Most of the greases I handle have a ASTM D1092 rating of -5 to -20 deg. F in the NGLI #2 viscosity.
