Hydraulic oil for models - what's in it?

[JAMMER]

Joe here is another little bit of info if you have water problems in the winter put some alcohol in the fuel and it will take care of the problem all except for the Mack they use to have a little scraper filter and that is were the alcohol would stay and it would not burn it I use to use the alcohol if I started to freeze up and then at night empty the file. A Cummins and a cat love alcohol. Dry gas works but alcohol works better Ed
