He cant use the force. hes a droid (mostly)
you DO NOT need force sensitivity to wield lightsabers. you can become pretty good at saber combat, but without force sensitivity u will always lack "jedi reflexes" and thus would not be as fast as a force user with a saber nor could you deflect laser bolts.
I hate to break everyone's hearts here, but I do seem to remember something that might throw some fire on this debate...
I do agree that according to the movie, Grievous did not appear to have force powers.
If you include EU though, there is a comic that hints at the possibility of Grievous having a connection to the force. It was the comic that explained General Grievous' origins.
In the comic, Grievous received a blood transfusion from Jedi Master Sifo Dias. It is implied that the blood somehow transfers some slight force ability to the General.
But EU commonly contradicts the movies, so you have to take it with a grain of salt.
As far as the cartoons are concerned, Mace Windu could fly through the air like superman, so Grievous having the ability to jump does not make him force sensitive.
Here is a pic from the comic I mentioned:
