Do not go here!!! They are shady. I would be willing to bet money none of the 5 star reviews on here are even real. I called to see if he could look at my truck and what hed charge to diagnose it not starting. He said he knew everything about my specific truck and could fix anything on it easily. He quoted me a price and said he could work on it immediately. I paid to tow it there for $300 and was immediately worried by my decision. When he didnt call me with a diagnosis by the following day I decided to check in. I called a dozen times but no one ever answered. I drove there to see my truck outside the gate in a bad part of town with my keys inside and it hadnt been looked at. The sign said it was open but everything was locked up and dark. This was a Tuesday at 2pm. I called again the next morning and he finally answered. He said a part I already replaced myself days prior was bad and that there was a problem with the computer and electrical that made it impossible to tell what was wrong. I spoke with another mechanic and he said what he told me wasnt true and that he should be able to use the diagnostic computer to find any shorts. I think he thought I wouldnt have the money to get it towed back and hed get to extort me to keep my truck but I paid another $300 and brought it back immediately. They locked my keys inside and parked it in the back of the gated lot with a broke down semi in front of it but the tow company I used was a friend of mine so they did what they had to do to get it while all of them stood and stared rudely as they did. I guarantee theyve done this scam on others. Good thing I didnt choose the company they recommended... Im sure thats likely part of the scam. The best part? I know they didnt even pop the hood as I had unhooked both batteries prior to sending it in and they were still unhooked with the lines tucked back like I had done.

Great people got my trailer working in no time !!!

Helpful people, quickly repaired my trailer and got me back on the road!

Great shop, I did engine rebuilt for Detroit and will be bringing more trucks there.Owner very good personI do recommend that shop !

Outstanding work! They got me out of a bind many times! The work, price and professional craftsmanship is second to none. They keep my 3 big rigs and 4 trucks operating daily. I would highly recommend Bull Dog Diesel.

Taken my truck here a few times and is the best diesel repair I’ve found. Manny is very professional and friendly had my truck for almost a month while I got the funds together and waived the storage fee. Best repair shop in OKC HANDS DOWN

This is the absolute worst place you can take your vehicle. Do NOT take them here. They took parts off of our truck and made us pay for the parts they took off!!!! The guy messaged us via text and was a complete jackass... ive never had an experience with a auto repair shop... this is the worst place ever. Trust me do not go there...

** Dont mind my account name! Lol **My name is Ellis Gibson Im a local out of you Yukon. I called Manny up at Bulldog on monday about a clutch job I needed on my Freightliner. Dropped it off in the afternoon and had it done and picked up the next day. Short simple and sweet. And his prices were the best I could find in Okc! Good group of guys, thanks manny!

Nice people very professional. I highly recommend this shop.

I called them about a truck that lost power . Manny was there in 45mins and worked all day in the heat found the problem got it back to his shop and had us up and rolling the next day. Awesome service!

I’ve been taking trucks to Manny for almost 5 years. They have always been on the ball whenever I needed them. He even let me park my truck there if I needed to. Any time I had any sort of trouble, one phone call solved it. Parts waiting for my truck or a mechanic on his way ASAP. I’ve trusted him with all my trucks and will continue doing so. Good mechanics are hard to find and I found one. So Bulldog’s diesel has my business for the foreseeable future and if I were you I’d give him your business to.

Took care of my fueling issues and got me back on the road quick. Knowlegable on the cummins common rail and explained what was going on so I understood my issue. Even fixed my water in fuel code I could never get cleared.

Manny is Awsome! Took my truck to the dealership and they couldnt even figure it out. Him and his guys figured it out, fixed it and was very fair and flexible with me on my repairs. He has my business going forward for sure!!!

BEWARE OF THIS EXCUSE OF A SHOP.Unprofessional, rude, do not waste your time with this place.My driver broke down in Oklahoma City OK, I fount this place on NTTS, the person that picked up sounded like a professional, assured me that he will take care of the truck ASAP. Truck got to the shop on Thursday 07/12. Manny promised that the truck will be fixed by Monday. Manny was very well spoken and i had a feeling that my truck is in good hands. Ohhhh I WAS SO WRONG. Monday came and it started. On Tuesday i confronted Manny and asked what is happening. He did not tell me anything quoteit is hot as hell in here we are working our asses off. After Tuesday Manny was not picking up his phone for two days. I had to call from different phones to get a hold of him, to only hear that the truck will be done tomorrow by 5 pm. it continued until Thursday. On Friday they finally started working on the truck, and guess what the truck is working the same way as before they did anything to it. Manny was holding our truck hostage until we payed him. He wanted us to pay him with a bank transfer, he wanted us to pay before even my driver could test drive a truck. When we told him that we will pay with a credit card he said that bank transfer only or com check or t check. it was around five pm on Friday so even if we wanted we could not transfer money. He said if we cant transfer money today we would have to wait until Monday to take our truck because he must receive payment first. We could not pay because it was late, so we ended up with a credit card, and thank GOD we did. Because the truck was not fixed, being there for over a week. And after we payed Manny was sending me text massage with a electronic receipt and said to put a SMILEY face? and write good job on there???? I did not do any of that. and most important before we payed he sent us an invoice with 1 year warranty. after transaction came through he sent us a revised invoice stating no warranty engine is damaged. The worst experience that we had with a truck repair in 12 years. Do not use this shop under any circumstances. Stay away.

These guys are awesome!!! Had my clutch replaced in the same day. I am back in business!!!

Very helpful guys anytime of day. I broke down at 3AM on I35S. I called Manny and he had someone on the way within 5 minutes. The service was fast and professional.

Really good service and reasonable prices. Owner is very personable, I would highly recommend.

Highly recommend this shop. Technicians are very knowledgeable and fast turnaround.

Told me show up at a certain time. Then no one even there to do the repair or figure out what was wrong. Wow!

Very professional!I broke down outside of Oklahoma City and Mannys mobile mechanics were able to diagnose the truck on the spot.Bad ECM.I had a wrecker tow me to his yard and within a half hour Manny himself confirmed a bad ECM.Manny gave me a ride to a hotel so I didnt have to spend money on a taxi or Uber!I fully recommend using his shop.

Good work and good price friendly

Reliable, friendly and responsive!

Very nice guy!!!
