My car received the *most excellent* and I received *such kind* service from Kentrell; the best I’ve ever had for getting work done on my car, or any dealings in recent memory. This young man went way over, above, and beyond to make sure that I got the best products and service for my money. He actually reminded me of how very good my own husband is to his customers. He was extremely knowledgeable and his kindness and behavior were very much appreciated - so very refreshing. I have no doubt that this awesome young man will someday soon be running his own company. He is who I plan to work with in the future and my husband fully agreed. We wish him, as well as Duke of Oil, every blessing and success!

I have a problem with my cars oil consumption. First they always check the stick before the oil change and notate it on your record. Then they had the employee catch the oil coming out of my engine during the oil change so I could see the amount left in my car. I was pleasantly surprised at all the brands of oil offered. I never saw an offering like theirs. I was able to buy the Premium Mobile Synthetic oil I wanted. Previously I found immediate help when my tire was running low. Even though they are quick, they are more than happy to go out of their way to help you if they can.

Best service. Staff is always helpful and friendly. Always quick. I work a long distance from home and I’m on the road a lot. I get home late and have barely made it there in time before closing. They wave me in and take care of my car which keeps me safe on the road. I appreciate that more than anything.Services: Air & cabin filter replacement

I sat there for 15 minutes, and no one came out to greet me, even to say hello. so I left. I will give them another chance as the location is very convenient.

Every single time I come here, every worker is super friendly and kind. Ever since I happened upon them, I drive out of my way to go back. For some reason, I hate going to get my oil changed, but they really make it no problem at all! They are awesome!Service: Oil change
