At Blarney Castle Oil we have been dedicated to customer service since 1933 when our first store opened, and that remains our primary goal still today. When Blarney Castle #2 gas station first opened its doors in Bear Lake in 1933, the station’s owner — Denny McCarthy – prided himself on providing “superior customer service. ” More than 75 years later, the McCarthy family remains committed to putting our customers first. As it was in 1933, Blarney Castle Oil and Propane is a Michigan-based, family-owned business. With more than 140 EZ Mart convenience store locations today, propane and fuel oil service, commercial fuel and bulk lubricant sales, our primary goal is satisfying our customers. We are dedicated to providing you with fair and competitive prices, with nine offices in Michigan to serve you. As we look ahead to the future, we are grounded by our humble beginnings and grateful for the opportunity to continue to serve our neighbors in Michigan.
