CH Yoke and Dupont Teflon Silicone

I have just purchased a ch yoke, and I am actually quite impressed by it. Despite its age, its much better than its Saitek equivalent, and actually adds to the flying experience instead of taking away from it. There is just one thing bothering me- the harsh friction in the plastic yoke, more the sound than sticking. After reading through the forums, I just purchased a can of Dupont Teflon Silicone spray. However, I checked that it does contain petroleum distillates, so is it safe to use on plastics like the yoke shaft? I would like this yoke to last many years and not develop any looseness in the the plastic bushings. Is anyone using this product on their CH yoke for an extended amount of time? Does it work well? Any opinions are appreciated. Thanks.
