I drove to The Smog Shop which was out of my way and told the owner what his friend said. Long story short - I did not receive any discount and when I told the owner he hadn't given me a discount....he assured me he had until I pointed out the price sign on his wall that clearly showed he had not. He then told me that everything has " gone up" and that he was less expensive than any other smog shop. That is not true. I had to listen to this guy bad mouth other smog shops stating they had "ripped off customers," but I don't see how he thinks he's any different. He could have told me from the beginning that he wasn't giving me a discount and then I could have left and found another less expensive smog station since his charges were higher than any other shop I've been to in the past. I let the owner know that I will not be doing business there again.

Today I was completely blown away by the level of service that I received from SpeeDee Oil Change…read more I was greeted by the nicest gentleman, Mike, to later find out that he is the owner of the location. He immediately made me feel super confident about the service that was going to be performed on my Audi Q7. His entire team was very attentive and gave me a feeling that every employee here had a sense of pride to be working with Mike and his team. They even were able to reset my annoying inspection required light that I thought only the dealership could reset. They completed my service and had me back on the road in a very timely manner. The value of coming here for a routine oil change compared to going to a dealership showed me that I have been throwing money away in the past. Not to mention the amount of time a dealership takes to make a simple oil change seem like an engine overhaul. This is my family's go to spot for a premium oil change with the confidence that Mike and his team will take care of our vehicles like it is one of their own!

I recently took my 2018 Dodge Ram Limited Edition to Valvoline for what should have been a simple…read moreand routine oil change. Like most customers, I trusted that a company specializing in oil changes would have experienced technicians who knew exactly what they were doing. Unfortunately, that was not my experience at all. After the service, I drove my truck home without noticing any issues. The next morning, I drove to work as usual, only to come out after my shift and find a large puddle of oil underneath my truck. This is a spotless, well-maintained vehicle that I take a lot of pride in, and it is extremely frustrating and disappointing that such a basic service was handled so carelessly. An oil change is one of the most standard maintenance procedures any automotive service shop performs, especially a business built around providing quick oil changes. I trusted that the job would be completed properly and professionally, but clearly that was not the case. What makes the situation even more concerning is the lack of experience and attention to detail shown by the staff working on vehicles. If customers are expecting knowledgeable and qualified technicians, they may want to think twice before bringing their vehicles here. To make matters worse, I contacted customer service immediately after discovering the issue. I was left on hold for over 20 minutes with no real answers or urgency shown toward resolving the problem. I was told someone would follow up with me and that they would "be waiting for me," but I am still waiting for any meaningful response or accountability. Overall, this experience was extremely disappointing. Customers should not have to worry about major problems occurring after something as simple as an oil change. I brought my truck in expecting professional service and left dealing with an unnecessary and avoidable issue that could have caused serious damage to my engine.
