Steering oil
 

Hello, I can’t remember the aircraft steering oil brand for replace the sea star steering, can anyone help me?

Go to any FBO and ask for aviation red hydraulic All the majors make it, Shell, Mobil, Texaco, etc....

I use it for Seastar steering, Jack plate, Bennett trim tabs & trim & tilt !!

FBO = Flight Based Operation / small airports...

This is the good stuff Ken mentions.

I recently inquired at my local airport. Didn’t catch the brand but was quoted $36/gallon. Guess I could go for a lifelong supply.

Casey then you should go this route!! :)

How does the viscosity of the red hydraulic oil compare with Seastar?

Conner, that's way too technical for me to answer!! However it feels, pours and acts like hydraulic fluid to me. :)

Connor, bottom line is if it is good enough to keep a plane in the air,
good enough to keep me steering straight in the water !!

Have used this hydraulic for 40 years with zero issues...

Same stuff. The only thing that separates any from regular hydraulic fluid is that it doesn’t freeze.

reason I ask: Its my understanding that the viscosity of Seastar oil relatively low. A thicker oil makes it a bit harder to turn the wheel but makes the steering a bit more positive. Given my 25s characteristics, positive is better.
