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.

In addition, the gallon can I received did not match the photo I selected on the order, but rather the photo of the multiple gallon cans in a case.

As above, it was about a two month wait for the one US quart size container. One wonders if there is not much of a market for small volume containers or alternatively, there is a large market? From a previous purchase, I was now aware of the new designer paint job Shell implemented on the fifties era metal can. Since Shell bottles the fluid for the automobile market in resealable containers, why can they not just repaint a few of the those containers? I do not buy into the idea of absorbing moisture, as if so, then the brake fluid reservoir sitting on the firewall is also a problem.

Product as expected but was on backorder for 2 months.

Shell has changed the paint job on the outside of the metal oil can again. I thought I had ordered the wrong stuff. Again, per numerous previous comments, the one US quart container should be a plastic resealable engine oil type container. I assume brake fluid does not eat up plastic.

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.

Since when did Hyd fluid gallon containers become non-re-sealable? For a small shop working on GA airplanes, this is not acceptable! Now, I have to transfer the fluid out of this old fashion beer can, that you need a pointed bottle cap opener to actually open and buy an empty 1 gallon steel can to put it in so, it wonât become contaminated between uses. What a terrible idea Aeroshell!!!

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.

Q: Would it be possible for you to issue COC if we pay the charge?

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 MIL-PRF-5606.....is this the same?

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