We learned a lesson this year. A few years ago we finally decided to buy a snowblower. Well as a…read moreresult of some light snowfall winters the past few years and some great neighbors that have sometimes cleared our snowy driveway while we were away or at work, we have only used our snowblower a couple of times. As we were preparing for this season our snowblower wouldn't start. With the referral from a local hardware shop, we found a great gentleman to fix our snowblower. He recommended that we use non oxygenated gas for our snowblower and lawnmower. The non oxygenated gas will last longer and not breakdown as quickly as regular gas. So we headed over to Duffy's which is just a few minutes from our house. They were actually closed however you can pay at the pump which is what we usually do. I noticed that not only do they have non oxygenated gas, but also racing fuel, do car repairs and have a ladies day. Yes a ladies day on Tuesdays. We are fans of the local places and family owned places and Duffy's is that type of place. Since this is our only visit so far, couldn't quite give them 5 stars. We'll be back again and hopefully check them out for some repairs, but hopefully not too soon with the car repairs.

I came to Duffy's with oil, filter and drain plug washer in hand because I was particular about…read morewhat oil, filter and to make sure the drain plug washer was replaced. I used NAPA Synthetic 5W20 oil and NAPA gold filters. I found out they were a NAPA service provider and I didn't need to bring my own oil, they already were using it. GREAT! Two oil changed later I was reading the invoice and they used 0W20. They tried to argue they are interchangeable oils and argued with me when I stated they are definitely not, especially on my car. I was pretty animate they stuck with the 5W20. I changed the oil myself and put the right oil in. They offered but I already changed it out after they tried to argue with me about it. I'm not going to argue residual film and sheer durability here, but they are quite different oils. I have a Hyundai Theta II 2.4L GDI engine that is known for its rod bearing failures. Taking a chance on switching oils that I've never used in nearly 100,000 miles and My background gives me quite a bit of insight into motor oils. This created a danger to my engine I was not willing to risk. I don't have a few thousand dollars laying around for a new engine. All that said. I don't think they are incompetent, I think they have wrong information and arguing with a customer about what oil they want in their own car was probably a bad idea. I had problems trusting mechanics, a lot of hacks out there that have no business working on cars. These are not those mechanics. I believe they are competent and the mechanic is skilled, just misinformed and bull headed. Now I am back to doing it myself because of this experience. Love ya guys, but do not argue with a customer about what oils they prefer. They have their reasons. And I'd advise never putting 0W20 oil in any vehicle that recommends 5W20 again.

I dropped the car off overnight and got a call first thing in the morning with a complete diagnosis. Josh worked with me on what I could afford and even let me know about finance options (No interest for 6 months - NICE!) I got the work done that I could afford, it was done quickly (before noon!) and it was done courteously. A huge "thank you" to the owner and employees for rewarding me for shopping locally.

Took it back to them to degrease, they sprayed it down maybe 10-15 minutes the first time, after I had to have it towed to a mechanic and have the serpentine belt replaced. My serpentine belt was soaked in oil and ended up warping and fraying. The manager said he's been working on cars since the 80's and that doesn't cause the serpentine belt to wear down, even though my normal mechanic said otherwise and there are lots of articles on it. I had to take it back in for them to degrease it properly on a lift for the second time after my belt snapped and frayed, manager fought me the whole time. Long story short, don't take your car here unless you can pay for the damages they will cause in the future.

Valvoline has a two-step process where the person under your car doing the work is prompted by a person next to your car yelling out checkpoints as these checkpoints are checked you have the confidence that every necessary step is completed. When I went to CarX for a refund, the manager, Dave was argumentative with me and mocked me. When I described the situation I had. He told me I didn't need to get snippy.

I was able to get the temp stable by blasting the heat but decided to bring it here as an official partner of the MN Wild and had an oil change coupon. All the front desk people were nice, Sarah, and Jim were kind and said they'd take a look at it for a nominal fee; nothing to write home about. After waiting all day, they identified that there was an issue with the thermostat and fixed that for around 2,000 dollars. Pricey, but whatever. A few months later, I had a coolant issue where the temperature was rising again and no warm air was coming out of the ac when I blasted the heat. Brought it in to TGK on a Saturday and was told that it would be at least until Wednesday that they could look at it. Brought it home, added some coolant, everything ran fine. A week later, it started superheating again. I brought it in to TGK on a Monday. All of a sudden, there was an issue where the coolant was getting into the engine and there was an issue with an engine head. I got a call letting me know about that and that the fix would take weeks. I asked about loaner vehicles and Jim said that they had none. Since they had already drained my oil out of the vehicle, and rendered it undrivable, I felt like I had no option other than to have the work done here. Jim told me that the cost would either be $4400 or if a new head was needed all together it would be $5200. I was also told I would be updated as the process went along and I would hear from them in a couple of days. I was hoping to hear from them by Thursday. I did not. I called the business on Saturday hoping for an update. The gentleman on the phone knew that it was being worked on but didn't have an update for me. Great... Jim called me the following Monday and said that they had sent out the head that was damaged and that it would be back in a few days and they'd fix it up and have it ready to go for me by Friday. Friday comes. I call to see when my car would be ready. Sarah answers. She said that they hadn't gotten it back yet but they would get it done by the end of the day when it did. I call at about 4. No answer. Jim calls me back and says that it won't be done until Monday but the head only needed covering and that it'll be the cheaper answer. Great. Two weeks without a vehicle has become three. Monday comes. I call in the morning at about 8 to see what the update is. Jim says that they'll be putting it together soon and that it'll be ready by the end of the day. Noon comes. No contact. 1pm comes. Contact Jim calls. He says that while putting it back together they discovered a hairline crack on the head and it needs to be replaced completely. They had this part for how long and they just now discovered this. No proof was sent to me. At all. They have my car. There's nothing I can do to move it. I feel powerless and helpless but to pay. Jim calls at 4. Says the car is ready to roll but there's a problem: the battery is dead. The car won't start. He asks if I want them to put in a new one. It's $300. At this point I'm already in the hole $8000 because of this place. I tell them I will take it myself. I get to the store. Jim is there. Jim attempts to be kind. I finally get my car back. As I prepare to drive it to home to check the battery myself as I've lost all trust in this establishment my drive is marked by a sweet smell and white exhaust: the signs of coolant in the engine. I drive it back to TGK. Jim sees no issue. He says I can leave it overnight. I express my disappointment that I already have been without a car for two weeks and that I'm not going to leave it only to be charged again. At this point, I'm out $8,000. Feel taken advantage of. Have ideas of failure to show care by this business and have no desire to return here again except for the off chance they can make this right. By the way...the battery is completely fine. No issues at all. Stay away from this scam of a business.
