Do you trust the fuel quality at gas stations in your area?
The North Carolina Department of Agriculture and Consumer Services received fuel quality complaints about 24 stations between Aug. 19 and Oct. 31, with 20 of them in Wake County. A state inspector paused diesel sales at a Raleigh gas station pump after finding sediment coming through the pump.
Why it matters
The inspections followed a driver whose engine stalled after filling up and a mechanic who suspected contaminated gas, showing how consumer complaints can trigger state fuel testing. Lab results identified sediment and water in fuel at several Triangle-area stations, affecting drivers who rely on these pumps for everyday fueling.
Inspectors confirmed fuel quality problems at five of the 20 Wake County stations that drew complaints, while lab tests found sediment in premium gas at a Costco and water and sediment in non-ethanol gas at a Knightdale car wash. The source does not say how the contamination occurred.
The players
North Carolina Department of Agriculture and Consumer Services
The state agency responsible for inspecting fuel quality and responding to consumer complaints about gas stations across North Carolina.
Costco
The national warehouse retailer operates a gas station on Wake Forest Road in Raleigh where lab tests found sediment in premium gasoline.
Speedway
The convenience store and gasoline chain operates a station on Creedmoor Road in Raleigh where lab tests found sediment in kerosene.
Sam's Xpress Car Wash
The car wash on Hodge Road in Knightdale, operated under the Sam's Club brand, where lab tests found water and sediment in non-ethanol gasoline.
The details
After a driver's engine stalled following a fill-up at a Raleigh station, a mechanic suspected contaminated gas, prompting a follow-up inspection that found sediment in diesel at the pump. Lab tests on fuel samples also found sediment in kerosene at a Speedway on Creedmoor Road and sediment in premium gas at a Costco on Wake Forest Road.
Timeline
Aug. 19: The North Carolina Department of Agriculture and Consumer Services began receiving fuel quality complaints about gas stations.
Oct. 31: The complaint period covered by the state's records ended.
Roadmap
The state's fuel quality program responds to clusters of driver and mechanic complaints by sampling fuel directly from pumps and testing it in its labs. This Raleigh-area case follows that pattern, with inspectors pausing sales at contaminated pumps until repairs are made.
Drivers who fill up at the affected stations may face fuel system problems such as stalling, so checking for symptoms after a fill-up is practical. Consumers who experience engine trouble after buying fuel can file a complaint with the state agriculture department.
The takeaway
If your vehicle stalls or runs poorly after refueling, note the station and report the problem to the state. Consumer complaints are what prompted these inspections and lab tests.
