Sta-Lube Moly-Graph Extreme Pressure Multi-Purpose Grease SL3144 - [Pack of 3] 3 Wt Oz., Extreme Pressure, Multi-Purpose Molybdenum and Graphite Grease

good price

I was looking for a substitute for the Lubriplate Mag-1 grease thats recommended for my Toro snowblower auger gearcase. The Mag-1 grease is expensive and hard to find locally. I found this CRC Moly-Graph grease to be a good substitute. One concern I had was that some extreme pressure greases contain sulfur compounds that will attack the copper in the bronze worm gears in snowblower auger gearcases. I called the CRC technical hotline, but they had no test data on compatibility with copper. So I ran my own informal copper compatibility test following the protocol of ASTM D130. I took a strip of clean polished copper, coated it in CRC Moly-Graph, and heated it over a boiling water bath at 100 Centigrade (212 Farenheit) for 3 hours. To my surprise, after 3 hours, the copper showed zero--and I mean zero--visual evidence of tarnishing or corrosion. It was better than the 1a visual reference strip in the ASTM D130 protocol. My conclusion is that the CRC Moly-Graph is very compatible with copper, and therefore will not damage the bronze worm gears in snowblower auger gearcases. However, when switching from a different lubricant to the CRC Moly-Graph, its important to flush out the old lube and get all the old stuff out with brake cleaner, so that any potentially incompatible materials in the old grease/lube dont contaminate the new CRC Moly-Graph. Another benefit of using grease instead of oil in an auger gearbox is that it wont leak past worn seals. However, it can be hard to get the grease into the gearbox. I use a large turkey brine injector syringe (not a baster, a syringe) and use it to inject the CRC Moly-Graph grease into the auger gearbox.

Quality. Good price

Excelente producto. Gracias

installed new camshaft.

preformed as expected, I was happy with the quality, price was reasonable although not a super deal, delivery was as stated, and I would purchase from the seller again.

Great deal

I lubricated my rv chassis with this product. Worked perfectly

Good product

Ill probably be able to use this material without a mini-grease gun, but FYI, these are meant for use in such a gun.
