Lou - When one examines the John Deere ETHER starting fluid contents, one finds the following chemicals (by wt.): ETHER (80-90%), carbon dioxide (5-10%), B200 base oil (petro-hydrocarbon at .1-10%) along with propane & butane (both gases at room temperature at .1-10%). When one "carefully extracts" the contents from the pressurized 7oz. labeled canister, one acquires very nearly 7oz of liquid fluid. I know by experience ... I have extracted some 3-4 canisters already. Clearly, one "looses" the CO2 & propane/butane gases during the simple liquid contents extraction process ... KEEP AWAY FROM FLAME & HEAT. The result is very cool/cold liquid hydrocarbon composed primarily of ETHER/B200 base oil contents; what I called the 80%ether & 20%alcohol => now read that 80-90%ether & .1-10%B200 base oil. Also, by the way ... ETHER boils at about 95F(~35C). Thus, it must be handled with GREAT CARE (safety first) ... it is gaseous combustible at elevated seasonal temperatures. Again ... KEEP AWAY FROM FLAME & HEAT. And again ... one should perform the canister liquid extraction process only in a well ventilated area to outside air ... due to the presence of propane/butane gases included with the CO2 lost to the atmosphere ...
