does adding oil in whistle mix reduces the sensitivity?

[FrankRizzo]

Yes, its primary purpose is as a "phlegmatiser", which makes the combustion more even and less sensitive to pressure spikes. It also helps the individual particles in the mixture achieve a cohesive grain, without air pockets, and consistent loading density.
