I brought in my 2004 Mazda Tribute for an oil change on January 30th. Four days later on February 3rd I noticed big oil stain in my parking spot. I've been using this parking spot for the past year and a half and it was dry until now. I added two quarts of oil just to be safe since I didn't know how much oil already leaked. I drove back to Honest-1 the next morning, February 4th. Technician said that after adding those 2 quarts of oil I was one quart of oil over, which means that I already lost a quart of oil in only 4 days. They said they don't know what caused the leak. My previous oil change was 4000 miles and several months ago, and if my car was leaking oil at this rate before, I would be out of oil in approximately 20 days. Honest-1 denied their fault (intentional or not, it doesn't matter) and refused to identify the problem. The technician wanted to clean the oil soaked area of the engine to have a better look at the leak source but the owner/manager told him to stop and return my car to me. That's just my personal experience with this place, obviously they have mostly good reviews so your results may vary. Comment from Brad M. of Honest-1 Auto Care Business Owner 2/4/2015We are sorry to hear of your displeasure. Please remember that we informed you at the time of your oil change that you had an existing oil leak. We informed you of the process to find the leak. I have shown you that your oil filter and drain plug are clean, so the leak is not related to the oil change. Also, you have overfilled your oil. We would be happy to help resolve the oil leak, and welcome you back to do so after you have had the engine steam cleaned with our vendor. Read more
