Good price. I ordered two quarts. Glad I did because one quart can was punctured and caved in. Small leak all over inside of box. Salvaged about 3/4 though.

the price is competitive to all internet sales, Amazon sells this type of hydraulic fluid of the same volume for ~$40.

As described. Was a substitute for Mercedes hydraulic fluid. Too bad the container isnât resealable but thatâs on Shell⦠Did a triple-flush of hydraulic system to get 13 year old fluid out. This is nice fluid.

Got this as substitute for AC Delco Auto Liftgate Hydraulic Fluid. Worked great, just wish the can was resealable. Only needed about 8 oz. This fluid is used on GMC Terrain, Cadillac CRX, Chevrolet Traverse and BMW. AC Delco rebrands Aeroshell 41.

I ordered several cans of AEROSHELL 41. The order process was straightforward, the website was easy to navigate, there was email confirmation, the product arrived in a timely fashion and it was very well packed. It was just an all around great transaction.

Q: Is a manufacturing certificate of conformance (C of C) available for this Aersohell 41 Hydraulic Fluid?

No, there is no C of C available. The only certification that is available is the manufacturers Certificate of Analysis (C of A). It must be requested at the time of order via the "Special Instructions" box.

There is NO Certificate of Conformance available for this product. Only Certificate of Analysis can be obtained and must be requested at time of order.

Q: Can this be used as brake fluid on an FAA certified aircraft or an experimental? It looks like transmission oil in the reservoir now. I was told by one A&P that it is hydraulic oil. Not brake fluid as in DOT 3, 4, or 5 in a car.

This is Aeroshell 41 fluid, and meets Mil-5606H requirements, which is the most commonly used hydraulic fluid used in GA brake systems. Refer to your aircraft maintenance manual to verify the fluid the OEM recommends.

Q: Is Aeroshell 41 Hydraulic Fluid considered Hazmat for shipping?

No, this material is not considered hazardous.

Q: Is there a published shelf life for this Aeroshell 41 fluid?

The Aeroshell re-test time is 3 years for the Aeroshell 41 fluid.

Q: What is the H designation in the MIL spec? I am looking for this the same?

The H is the specification revision. H is the most current revision.
