    Gasoline, although it may not _dissolve_ silicone rubber, will 
cause it to relinquish its grip and to effectively soften. Most 
containers of silicone intended for automotive applications will 
precaution against use on fuel systems.
    Granted, gasoline isn't exactly oil, but I've always wondered 
what exactly it was in gasoline that attacks the otherwise resistant silicone.
    I've never been impressed with the use of RTV silicone for 
sealing against oil even under the best conditions. Or even against 
water in outdoor applications. Personally, I don't trust it unless 
you completely _pot_ the item to be protected, or use pre-cured 
silicone gaskets.
