Grease Mysteries Solved

While far from any Snowden liek revelations here are some industry secrets that I am able to reveal.


While I can't reveal my source, I have 100% confirmation that Phil Wood water proof grease is a Product of Exxon Mobile.

here is a little comparison....

Exon-Mobile Mobilegrease 33
"It is made with unique synthetic base oil,  lithium complex thickener and premium additives to provide excellent corrosion and wear resistance, and operability at very low temperatures. Patent-pending technology What makes Mobilgrease 33 fundamentally different from other low-temperature airframe greases is the base oil. It contains no esters and is 100 percent polyalphaolefin (PAO). Esters are
compounds that are susceptible to hydrolysis, which is a chemical reaction with water causing decomposition and  leading to the likely production of potentially corrosive acids.  A patent for the base oil technology has been applied for by ExxonMobil and is pending.
• Unlike airframe greases containing esters, our product’s
100 percent PAO base oil will resist decomposition when
contaminated with water.
• Mobilgrease 33’s superior hydrolytic stability can provide
a higher level of protection for airframe components
operating in hot and wet environments."

...And here is what Phil Wood has to say about "their" grease:
"Phil Wood Waterproof Grease is used to pack all our Phil Spec’d bearings for maximum durability. It is tested and has achieved the “premium” lubricant classification by all major bearing manufacturers worldwide."
...not much insight. And  the MSDS

$13.50 / 14oz.

$10.00/3 oz.


While this is purely speculation The Motorex Bike Grease 2000 (Fett 200) looks the same, and feels the same as Shimano Special Grease (Dura Ace)
here is what Motorex has to sayabout it:
"Fluorescent yellow calcium-based grease with remarkable and durable lubricating properties. Motorex Bike Grease 2000 is a highly water-repellent, extremely pressure-resistant grease. Provides enhanced resistance to oxidation and aging. Ideal for lubricating bearings, hubs, joints and headset. Does not attack elastomers and seals and prevents galvanic corrosion."
While no official description of the grease from Shimano could be found, I think the case can be furthuer by comparison of the Material Safety Data Sheets (Shimano & Motorex). While this isn't conclusive evidence it is a strong case.
Both greases have are calcium based, have great sticky feel and rust inhibitors. At 10$/100g Motorex and $20/100g for the Dura ace special grease, the motorex seesm like a great value.

  1. Where did you get your Motorex in the vancouver area?

    1. house of chain on 4th and and Alma stocks it. Fett 2000!
