Our GOM says the following...

"SAE Type I fluid/water mixture is selected so that the freezing point of the mixture is at least 10 C (18 F) below OAT."

Nowhere does it give any data on a mixture of less than 50/50. I would assume this means you need at least 50% Deicing fluid.

Also heated to 180F, the FBO should have this information readily available.

Some trucks will automatically choose the mixture based on the OAT. But for most FBOs it is a 50/50 mix.
