A different but similar question: Do folks wash their rubber before using it?
Have read both points of view, might be good to have some of the top US fliers add their opinions.

FAI Model Supply sells silicone oil in a low and a high viscosity grade. The low is 500 cSt and the high is 5000 cSt. I have been using the 5000 cSt oil for all classes since I started out over ten years ago. Many indoor fliers today use the thinner 500 cSt but this is more a matter of personal preference. In practical terms, the difference in viscosity between 5000 cSt and 500 cSt is the difference between the viscosity of SAE 50 motor oil at 32F and 70F. Note that silicone oil does not show such a viscosity change with temperature.
Finally, many of the older indoor fliers take AmourAll (or Son of a Gun, etc.) and evaporate off the water (these are just a water and silicone oil emulsion) by putting the AmourAll in a shallow pan and letting it sit for a couple of months (perhaps on top of a water heater, etc.). After this time, only the silicon oil is left. I just find it cheaper and less of a hassle to buy from FMS.
