For a sticky gas pedal what is the best lubricant, WD40, silicone spray, or something else?

You did not specify type of vehicle but it could be that the throttle plates are sticking in the throttle body and need to be cleaned. If it is a cable problem, do not bother with lubricating it and just replace it. Do not spray any lubricant on the linkage as this is petroleum based and will allow dirt ti stick to the linkage causing sticking and binding.

I have always used WD-40....For a sticky gas pedal what is the best lubricant, WD40, silicone spray, or something else?
if the pedal is sticking and you can't control the engine speed, you should find out why. if it's a worn cable, replace it. trying to lubricate something that wasn't made to be lubricated is foolish. may work for a short period of time but do you want to take a chance on the accelerator getting stuck at the wrong time? if it's not the cable, may be a defective throttle body. get it checked to find out what is causing the problem and repair it properly. hate to be on the road with you if the pedal is stuck.
lithium grease


WD40 is penetrant and spoil the sensor.(TPS)
Spray white lithium grease will outlast both of those and do a better job it is also, available at any auto parts store or wal-mart. I use tube white lithium grease on the fifth wheel on my Kenworth T600, even in that very heavy duty application it lasts a long time. I don't know where you live but I, also know white lithium grease doesn't freeze having used it in -30 degree weather. WD-40 will freeze I have personal experience with this happening!!!!!
If you have a throttle cable that is hanging up don't use WD 40 because it will dry up and cause more troubles. I use a special grease that has graphite in it. This is designed for speedo cables. If the your cable does not move in and out of the cable jacket freely when it is disconnected from the throttle body or carburetor you may need a new one. The return spring might be getting weak or fatigued and should be replaced.
The throttle control cable may be worn,,causing drag within the outer harness,,,if that is the case,,no amount of lubricant will help,,,its cheaper and less of a headache, just to replace the cable and harness.
WD-40 works well.
make sure its not your floor mat. This has happened to me twice in two different vehicles.
for all the different kinds i used,i found out that pb blaster is the best.
