- LGLacy GomezNov 18, 20251.0This business lies about business hours it was after 5:30 and they weren't open stood there until 6 an nobody even tried to make contact
- KPKrissy A. PetersonOct 31, 20255.0I was taking a road trip thru South Dakota and stopped at this location late at night. I was able to find what I needed and get back on the road in no time. Also, your store was clean and very well-stocked and the gentlemen on duty was really nice. I'm sincerely looking forward to coming back to this location the next time I'm in the area.
- PMPilot MicMay 27, 20252.0Fair warning. The price shown in google maps is an E88/15% ethanol which is not standard unleaded of 10% with octane rating of 85-87. I didn't even see this standard there. First time ever seeing a gas station without a standard unleaded. Your car will not get as good mileage nor perform as well with the 88/15 blend
- CNcale nelsonJul 28, 20231.0Travelling with my daughter, she had a blow out diaper and the Sinclair did not have a changing table in men's room. Had to change her on the sinks and several people had to wait to wash their hands.
