Several drivers in east China's Zhejiang Province complained on Sunday that their vehicles repeatedly stalled after filling up with gasoline at a Sinopec gas station near Wenzhou, National Business Daily reports.

A test conducted by a repair technician found gasoline from one of the vehicles had a water-to-gas ratio of about 2.8 percent.

The drivers suspect the gasoline was mixed with water to increase volume and reduce cost. Staff at the gas station has denied these claims. They said previous maintenance work on gas station might have caused the problem.

Sinopec has promised to compensate drivers for losses caused by the faulty gas. The company is investigating the incident and will publish its findings on June 1, the director of Sinopec's Wenzhou branch said.

The Xishan gas station was remodeled in April and reopened on May 24, a station employee said. The incident was probably caused by improper disposal of test water used during construction or maintenance of the submersible pump.
