Test results of LPG quality updated

     The Electrical and Mechanical Services Department (EMSD) today (April 15) announced on its website the latest results of tests on LPG quality.  From early January 2010 to the end of March 2011, the EMSD delivered 164 LPG samples collected from 62 Auto LPG filling stations and five LPG terminals (see table below) to an accredited laboratory for quality tests against the Auto LPG Specification, which is available on the EMSD website: .

LPG supply company No. of samples
------------------ --------------
Chevron                      18
China Oil                     2
ECO                          12
ExxonMobil                   41
Feoso                         7
Shell                        22
Sinopec                      62

     The test results show that LPG quality does not affect the performance of vehicles.

     The detailed results of the tests on the quality of LPG samples are published and updated on a weekly basis and are obtainable from the EMSD website,, or upon request via the EMSD's hotline, 2333 3762.

     In addition, the EMSD has been vetting the independent third-party test reports submitted by LPG supply companies for each shipment to ensure that the quality of the imported LPG complies with the specified requirements.

    The spokesman said, "The department has been maintaining a 24-hour hotline since early January 2010 to monitor and follow up on the stalling of LPG vehicles.  As at April 14, 2011, there have been 195 reports on engine stalling incidents via the hotline with the majority received in early 2010.  From March 13, 2011 (i.e. the date of last press release on the same subject) to April 14, 2011, the hotline did not receive any report of stalling incidents and the department carried out inspections on two LPG taxis provided by the trade.  The breakdowns were found to have been caused by aged parts or incorrect adjustment of air-fuel mix ratio, and were not related to LPG quality.

     "Should an LPG vehicle be found with irregularities or malfunction during operation, the vehicle owner should as soon as possible arrange for the vehicle to be inspected and repaired by a competent person with relevant experience and training according to the maintenance manuals of vehicle manufacturers.  The vehicle owner may also report detailed and specific information on the stalling incident through the 24-hour hotline 2333 3762 for follow-up action and assessment of the situation by the department," added the spokesman.
