A new report from the Texas Department of Agriculture finds drivers are being cheated at the pump.

The state says one company, that has stations across the state, has not been giving drivers all the gas they've paid for at the pump.

Agriculture Commissioner Todd Staples Tuesday unveiled the results of "Operation Spotlight" -- a three day investigation into Petroleum Wholesale LP fuel stations. The company operates under the name Sunmart in Texas.

The investigation confirmed numerous stations cheated Texas drivers by giving them less fuel than they paid for.

The three-day operation ended on Sunday, July 20, with the following results:

-- 990 of Sunmart’s 1,704 fuel pumps cheated consumers (58 percent)

-- 47 Sunmart stations cheated customers on more than half of their pumps

-- 15 of those 47 stations had every single pump cheating drivers

TDA shut down all of the non-compliant pumps

"While these results are damaging enough, I believe the facts would have been even more incriminating had the company not dispatched a band of technicians scurrying to get ahead of my band of inspectors, in order to recalibrate faulty fuel pumps," said Staples.

Staples said he initiated “Operation Spotlight” after becoming aware of some violation patterns that pointed to the possibility of Sunmart intentionally shortchanging Texas drivers.

The company could be fined more than $100,000 for its actions, which Staples says he believes were intentional.

State Attorney General Greg Abbot is also launching an investigation, which could result in civil and criminal charges.

There are three Sunmart stations in Central Texas -- one is in Georgetown. The majority of the Sunmart stores are in the Houston and Dallas areas.

Besides Texas, Petroleum Wholesale, L.P. operates Sunmart fuel stations in Oklahoma, Kansas, Colorado, Utah and Arizona. Commissioner Staples has alerted regulatory officials in these states to inform them of this investigation.

“While this specific operation may have ended, we are far from finished,” Commissioner Staples said. “We are going to shine the light on all violators who are looking to shortchange Texans. I will not stand for companies taking advantage of good citizens and I will work hard to protect all our consumers.”

TDA inspectors will conduct follow-up inspections on each gas pump that was tagged out of order once it is recalibrated. They also plan to conduct re-inspections in the coming weeks on a random sample of the Sunmart stations. If they find continued violations, the penalties could be much higher.
