Aeroshell Grease 22

Sale AeroShell Grease 22

One Choice

There is still no perfect grease for all occasions. You could get away with one choice - probably with Shell 22, a wide-temperature-range synthetic - but we prefer to make two recommendations. You will still only need one grease gun, as one of our two recommendations is strictly for wheel-bearing use.

Interestingly, the use of automotive needs is not a major element in selecting aviation greases. In the auto world, everything is punctuated with extreme pressure (EP) additives such a molybdenum disulfide.

Could you get away with using auto grease in an airplane? It's done every day, but considering the low cost of grease on a relative basis for the individual, why not go with the established and recommended products?

Aviation greases are definitely different from the automotive brands, particularly when they are based on specific standards of cleanliness and what is in the product.

Planes that fly high or in cold weather should definitely stick with the proper selections, since improper grease can become like glue when it's cold enough. Try hitting the tarmac at 100 knots with frozen grease in the wheel bearings for a life-shortening experience in wheel-assembly components.
That squeal you hear is not a pig on the runway, but your bearings pleading for mercy. Fly low and slow and park in nice, dry, warm weather and you might get away with Crisco in the Zerks -- not recommended.
