This was my second visit to Brake Masters on Tropicana and it will be my last. I had purchased a card to get service and oil changes (3) for $35 from groupon for Brake Masters. On my first they changed the oil in my wife's Camry and gave me a long list of items they said needed attention one of them being that it needed a new air filter. I had just put one in 2000 miles before so I told them not today. \nWhen I got home I checked things out under the hood and they had left a bolt out of the filter housing and now it is lost.\nI thought oh well it was just an oversight and would try again with my Jeep. So I take it in and they do an oil change and filter and were supposed to lube it. They get it done in less than 30 minutes and I am on my way. I went to put the receipt away and notice on it that they used 5w-20 oil in it and so take it back. The manual says that grade of oil is only to be used if maximum temperature will be 60* . So the manager says ok we'll make it right and gets it on the rack they drain the oil and start to lower it down so I asked what about the filter it has 1/2 qt of wrong oil. So the guy asks the manager and he said ya go a head and change it again. So they change it and drain the new one and put it back in the box to be used on someone else's car also the oil they drained out they put in a clean pitcher and poured it back into the oil tank. Now all the oil is contaminated with the mixed oil from my jeep and the new oil.\nThen the manager tells me that the 5w20 is a better choice than the required 5w-30 that jeep recommends. This in my opinion is reason enough to not go back, until I climb und the jeep and find that they did not grease anything and also disconnected the breather for front differential at the pumpkin which if I was to go through any water would contaminate the oil.\nThe total lack of concern on what type of oil and lack of skill that they have at this business warrants not going there again. I hope this helps at least one other person. I you do go there please double check their work.
