Delmar's Service is a full-service gas station with an attached service bay located on the south side of Oklahoma City, combining fuel sales with light mechanical work and air/tire services. It operates independently rather than as a branded chain, which shapes its pricing, availability, and the range of problems it can solve on-site.
This is a traditional neighborhood gas station built around the model of the 1980s and 1990s: pump your own fuel, but walk inside to a staffed service counter where you can request tire pressure checks, battery testing, windshield wipers, air filter replacements, and basic oil changes. The service bay handles jobs that don't require a full diagnostic lift or specialized equipment. It does not perform transmission work, engine rebuilds, or frame work. Most customers pull in for fuel and leave; some combine a fill-up with a quick repair or maintenance task.
Fuel prices track the wholesale market and shift weekly; call ahead or check the pump display for current per-gallon rates. The service bay charges $45 per hour for labor on jobs like oil changes, battery replacement, and belt work. A standard oil change runs $35 to $55 depending on oil grade and filter type. Air in tires is free. A tire patch costs $15. Windshield wipers are sold at $8 to $15 per blade, installed on-site at no extra charge. Battery testing is free; replacement batteries range from $80 to $160 depending on CCA and type. Diagnostic work carries a $20 fee that applies toward repair if you proceed with service.
Most major chains in Oklahoma City (Murphy USA, Love's, Pilot) operate as fuel-only stops with no service bays; they prioritize speed and volume. QuikTrip locations in the metro area have no service capability at all. Independent stations like Delmar's fill the gap for drivers who need a quick fix without booking an appointment at a full dealership or shop. Compared to dedicated quick-lube chains (Jiffy Lube, Valvoline Instant Oil Change), Delmar's is slower but cheaper on oil changes and doesn't upsell as aggressively. For anything beyond basic maintenance, you're still going to an ASE shop or dealership; Delmar's knows its limits and directs customers appropriately.
Delmar's works well for drivers on tight budgets who need a $40 oil change or a $15 tire plug and don't want to book an appointment three days out. It suits people with older cars who know what they want fixed and don't need hand-holding. It does not suit anyone diagnosing a check-engine light or needing computer-based diagnostics beyond a simple battery or alternator test. It is not a full-service repair facility and does not pretend to be.
Pull up to a pump, fuel up, and walk inside. Tell the attendant what you need. If it's simple (air, wipers, battery test), you'll wait 5 to 10 minutes while they handle it in or around the bay. If it's an oil change, expect 20 to 30 minutes depending on whether they're backed up. You can pay at the pump or inside. No appointment is required for small jobs, though calling ahead can reduce wait time on busy afternoons.
Delmar's is open 7 a.m. to 7 p.m. Monday through Saturday and 9 a.m. to 5 p.m. Sunday (verify current hours by phone, as these can shift seasonally). Parking includes four spaces directly in front of the service bay and six standard pump islands. The lot drains poorly after rain, so avoid deep puddles near the eastern pump row. The building has a single restroom accessible to customers.
Delmar's Service survives in Oklahoma City by solving the problem between a gas pump and a full repair shop: quick, affordable maintenance without the wait or the markup.
