Important Safety Notice Regarding Methanol
AEM strongly recommends that users never exceed a 50% methanol concentration when
using any AEM Water Methanol system or component.
All AEM water/methanol injection systems and components (pump, lines, fittings, filter, flow
sensor, tank, and nozzles) are 100% chemically compatible with methanol. However, for safety
reasons we strongly recommend that users never use more than a 50% methanol concentration
in our systems.
Methanol is a toxic and highly flammable chemical. 100% Methanol ignites easily and burns
vigorously with an almost undetectable flame. Methanol can be absorbed through the skin and
even small amounts can cause blindness or even death. Using this fluid at high pressures,
without dilution, in an under-hood environment with nylon lines and push-to-connect fittings is
very unsafe. The performance advantages of using greater than 50% methanol concentrations
are small, if they exist at all. However, the safety issues are very real and far outweigh any
perceived benefit of running high concentrations of methanol.
Note: AEM holds no responsibility for any engine damage or personal injury that results
from the misuse of this product, including but not limited to injury or death caused by the
mishandling of methanol.
Cold Weather Operation
A Water/Methanol mix will also lower the freezing point of the fluid. Below is a chart with
freezing points for different percentages of water/methanol mixtures.

Maintenance
The injector nozzle should be cleaned periodically. Disassemble the nozzle and clean it with a
suitable cleaner until all debris is removed. If excessive contamination is found check the rest of
the system for the source.
