KSWO does offer full-service Jet-A fuel.

My son attends OSU, so I visit the area about six times annually. Tim and his team are consistently very cordial, supportive, and accommodating. They deliver excellent service at fair prices.

Flew in from KOUN, was met with mediocre intercollegiate trash talk and a golf cart ride to the FBO. Was then given their worst minivan ($20) they said was "the special van for Sooner fans". Probably the most pleasant interaction I've had with an OSU fan, so I cannot complain too much, honestly.

The King Air 200 is $40 per night.

We flew in to drop off a passenger. They parked us in the far northeast corner of the ramp even though the ramp was completely empty. They transported us via ground transportation to the FBO (aircraft parking ramp and FBO are not even within sight of each other, and TSA has a restricted area you cannot enter on foot) to drop off our passenger, and we were informed there is a $110.00 fee specifically for King Airs. It seemed like young staff were managing the FBO who lacked knowledge regarding why fees weren't posted anywhere visible. It is advisable to call ahead for current pricing if utilizing this sole FBO.
