I bought one of those Tire Works peeler stickers with the intention of getting a few free oil changes. They are obviously a ploy to get you into the store. They are friendly at the counter however you are not getting any real discounts on oil changes. Go to Jiffy Lube if you want an oil change don't go there. I waited 2 hours because they didn't have my oil filter in the shop. Then I realized there was an oil leak from them not doing good work and verifying their work before they give it to the customer. So I ended up getting in a a phone call and email battle with Carmen Gomez. I tried to overlook everything and give them another try because Carmen promised a free oil change. I emailed her and even left a voice mail to get my free oil change she promised but was simply ignored.  I went to the Centennial store and tried to call her. Todd upfront even gave me her number. I was there because I had 3 cars that needed oil changes. Well they got my business for one vehicle but I realized I won't spend another dollar there. When my oil change was done one of there workers left oil on my key chain, oil on my door handle and on the inside of my truck where the door handle is and steering wheel. I politely asked Todd if I can have a rag and windex. He was annoyed that his worker had done such an unprofessional job. If you asked me, I think his worker was on drugs. They also claim they have a corporate office. However, it's just smoke and mirrors. I plan to contact the owners Roshie and Jeffrey Weightman. Please read the emails threads on my Google Reviews.
