Anyone can get a no-cost test of their vehicle’s gas cap, and a free replacement cap if a leak is found, at events coming up across Northwest Ohio.

Leaky gas caps are a preventable cause of ozone pollution. A broken or missing gas cap can also reduce fuel efficiency by 1-2% and cost up to 2 full tanks of gas each year.

Toledo Metropolitan Area Council of Governments will offer free gas cap testing and replacement:

· 11 a.m.- 2 p.m. Tuesday at Perrysburg High School, 13385 Roachton Road.

· 11 a.m.- 2 p.m. Thursday at Westgate Village, 3450 Central Ave., Toledo.

· 11 a.m.- 2 p.m. July 28 at the Woodland Mall in Bowling Green, 1234 N. Main St.

Drive up to a TMACOG testing site, and staff will do a quick compression test to make sure the cap is sealed. If it’s leaking, get a replacement on the spot. Receive a bonus gift while supplies last.

Older vehicles are more likely to have a poorly sealed cap, but any vehicle could be leaking. A loose gas cap may trigger the check engine light, so if the light turns on randomly or right after filling up, the cap may need to be replaced.
