Logos and Font Help

[SpeedDemon39]

I need help with the following logos I can't identify:
The logo above Southern Pan Services (SPS)
The logo above Miller Welders

and

The R. Truex font. I know it's on NASCAR The Game 2011 (because it's one of the font choices in the paint booth) but I can't identify the font.

The logo above SPS is Robert's Oxygen and the logo above Miller is Schaeffer oil.
