Also that it doesn’t cool very well (about half as well) and is much thicker than water.
If you have lots of cooling and not driving city it’s fine and it should gain FE because you run hotter temps but you can also wear out your engine faster and need higher octane if your motor naturally runs on the hot side. (Oil thins out with heat, preignition intensifies at temperature)
