What type of oil do you use and where do you get it?

BEST ANSWER: If you are using a thermal fogger we recommend odorless mineral spirits. They can be found at any hardware or home repair store. We carry mineral spirits in a 55 gallon drum if you are interested in that... It should be about $10 per gallon at the hardware store.
