This company sets the bar for reliability, competency, and great friendly costumer service. Thank you and keep up the good work!

I like Mahoney Oil Co. they offer free air for your tires unlike any other gas station you have to pay in order to use Mahoney offer air for free thanks Mahoney!

Woke up to no heat and a load of soot in the basement. Called into the answering service and got a call about 15 minutes later. Thank goodness the outside temp was in the mid 40s so we were not really cold. The Service man came and we found out we needed a chimney company to come in. Joyce referred Jim Sullivan. I called and left a voicemail, 5 minutes later he returned my call and was at our home in an hour. A couple of hours later the issue was resolved and all was fixed. We are a second generation Mahoney Oil Customer and with customer service and focus like this, we will continue to be.

They have good pump, but the people at the window [ cashier] they always are rude and unprofessional with everybody special in the midnight shift

Great location for this gas station right at the Lowell connector

Best in Class

I have been using Mahoney Oil for years!! They are always there for me. I have a problem with my burner, they are very quick to get me going again. They have a great crew and they all are so professional in the work they perform. Sure, I could save a 10 cents on oil shopping around but I like having the security and peace of mind I get with Mahoney Oil. The girls in the office are always so friendly to me when I call. Sure!!, we will have someone right there!! No worries!!Works for me!!! dave anderson, Chelmsford
