    Went in for a oil change. The short Latino had no clue what kind of oil to put in even though it says right on the oil cap.5W-30 viscosity oil (synthetic or conventional). I told him what kind to put in and to make sure it was synthetic. When I walked up to my car to make sure he was putting in the right oil he barked at me saying " I've already started putting in the oil, if you want me to change it I have to take it out and charge you extra." He said he was putting in the same oil 5w 30 just not synthetic so I asked the older white gentleman if that would be ok. He told me yes. I left and the next day I noticed they put in 10w30. It was on the receipt and the sticker they put on the window. So I called the older white man and he started yelling at me and my son. I told my son to hang up and tell him we will NEVER GO THERE AGAIN! I then took it to a family mechanic and he explained to me that it could cause so much harm to my engine. Also, because we didn't have the verbal agreement of the 10w 30 that I could sue if anything happens to my car. I had to get another oil change and they even changed the oil filter that the short Latino said was bad. ( The short Latino said the oil filter was bad but didn't or put a bad one in) My car was not leaking oil before I took my car there and now it is. Also, I noticed my gas cap is different. They stole my gas cap and probably are going to sell it or use it on another car. My mechanic told me that a gas cap not made for my car could ruin my engine. What a horrible experience! I'm trying to maintain my car and keep it running instead these people are trying to make sure that my car breaks down I hope that nothing happens to my engine because I will be fine in a lawsuit and contacting the proper authorities. The oil cap states 5W-30 viscosity oil (synthetic or conventional. Using the wrong engine oil can cause immediate issues like poor engine performance, strange noises, or a burning smell, and long-term damage such as increased engine wear, sludge buildup, reduced fuel economy, and potential engine failure due to improper lubrication. A 5 year old could do better.

    James was the kind of person you notice because the process feels smoother around him. He didn’t talk in circles or make promises he couldn’t keep. He gave a clear read on what was happening, what the next step was, and what information mattered. It felt steady, fair, and handled with real competence.

    I own two companies and trust Jim with all of our vehicles, including my personal car. He handles everything from engine rebuilds and transmission work to brakes, tune-ups, and routine inspections. His pricing is very reasonable, he’s extremely fair, and his work is top-quality. Jim is an amazing owner and mechanic—I couldn’t recommend him more.
