Henley Pacific LA LLC — a subsidiary of Newton, MA-based Henley Enterprises Inc., the largest franchisee of Valvoline Instant Oil Change (VIOC) shops — has acquired Synfast Oil Change, a 31-unit quick-lube chain in southern California, ranging in location from Bakersfield to San Diego. The shops are now operating as VIOC service centers.

Financial terms of the transaction were not disclosed. It marks Henley’s largest acquisition in southern California since it acquired 71 EZ Lube shops in 2012.

“Growth is a major part of our culture here at Henley,” said CEO Don Smith. “This acquisition gives us over 100 stores in southern California and makes us the dominant player in this huge market.”

The move gives Henley more than 200 service centers across 10 states: California, Delaware, Florida, Massachusetts, Maryland, New Hampshire, New Jersey, Pennsylvania, Rhode Island and Virginia.
