Open /etc/sudoers file with your favorite text editor as root, then remove comment character, #, in front of line "%wheel ALL=(ALL) ALL" and save.
# nano /etc/sudoers
# Uncomment to allow people in group wheel to run all commands
# %wheel ALL=(ALL) ALL
Change above line as in below and save file.
# Uncomment to allow people in group wheel to run all commands %wheel ALL=(ALL) ALL
You need to add your user name to group wheel also.
# gpasswd -a user wheel
(Replace user with your user name)
Now you can execute some privileged commands using sudo as user without becoming root with su. For example it is possible to edit system file inittab as user executing below command.
# sudo nano /etc/inittab
