We have been bringing our cars to Sean for years and can not recommend him more! It’s hard to find a trust worthy mechanic that isn’t trying to upsell you on every little part, but it has never once felt like that. He truly cares for your safety and what will keep your car running the longest. And he’s quick! Best shop in town

These guys have taken care of me every time I’ve brought my truck in. They do an outstanding job with high quality parts and are extremely knowledgeable about Diesels. Combined with amazing customer service, Trilogy Diesel is the only shop I will take my vehicle to.

I first heard of Robert's Automotive when I was looking on the Bulletproof Diesel website and saw they were a preferred installer. After seeing all the positive reviews I decided to call and make an appointment for my 2006 F250 6.0. Sean was extremely knowledgeable and helpful in explaining the process and what my options were. Unfortunately, I needed more work than just "bullet proofing", but Sean was upfront about costs and patiently walked me through everything they were doing. I cannot be happier with work performed by Robert's Automotive. All of the mechanics are extremely professional and courteous. My pickup runs great and gets better mileage than it ever has. Next time I need work done on my diesel I will definitely be going back to Robert's Automotive!

A neighbor recommended trilogy diesel. They got me in quick service was top quality in my opinion. I’ve had my diesel truck to a few shops and By far, this is the best shop that I have been to in the butte area. The quality of service they offered, and the customer service that was provided. Will definitely be bringing me back every time..

Sean and his team are great. After taking my truck to a different place and having a terrible experience, I called Sean and immediately knew I was in good hands. No fluff they assessed the issues that needed to be addressed and communicated with me the route we needed to take. Telling me that some parts I wanted to be replaced didn't need to be instead of just doing it and taking my $$. The honesty and communication when working with a mechanic is just as important as the guys behind the wrenches. Roberts Automotive will be the only shop that touches my old girl!

A friend recommended Trilogy and boy do I wish I had gone to them sooner! I was so impressed by Sean and his crew and the work they did on my truck. But mostly Sean's honesty and integrity was standout! He went the extra mile to get my truck in and out of there as soon as possible. It's hard to find a good mechanic that's trustworthy and readily available. Sean's secretarys were also very kind and helpful. I can't recommend Trilogy enough. I'll definitely be sending all my friends and family members to Trilogy from now on!

Sean bullet proofed my truck 6 yrs ago and it still runs strong. I recently had trouble while out of town and Sean troubleshot it over the phone and walked me through what to do and I was back on the road in 30 minutes. Very knowledgeable trustworthy shop

Wonderful place to get your vehicle repaired. We took in our '06 GMC Diesel to have some work done. While there a small accident happened to the truck. The owner took care of all of the expenses to have some body work done. The total experience was fantastic. We even took our gas truck to be serviced there after all that. Will be bringing our trucks back for more when the time comes. Highly recommend! Great owner. Great customer service.

Had my 08 Duramax front end rebuild with Kryptonite upper control arms, ball joints and tie rods. I highly recommend Sean and his team if your looking for professional Diesel mechanics. These guys went through my entire truck. Sean provided me with a list of what needs to be done now and what may be down the road. Honest guys that had my truck done on time at the quoted price

They recommended and installed a Mishimoto coolant filter in a Ford 6.0 diesel. When I changed the filter it was full of sand. Good job guys! Not you Ford, you suck. I can’t wait to see what the oil cooler looks like after all that junk in the cooling system.

Sean...... and his team have taken care of me from the moment I called them in the little bit of issues I’ve had with my F350. Definitely highly recommend these guys they know exactly what they’re doing and they take care of you. If I had a better picture of my truck, I would post it but these guys are amazing. Thank you for taking care of my truck.

I had a timing cover leak in my 2016 Ram Cummins. Sean knew exactly what to do and has done many of these repairs. He did it right, cab off, upgraded water pump, upgraded gaskets on the timing housing and oil pan. He installed a Banks Monster Ram to avoid the grid heater bolt issue ( at my own request) and was fully enthusiastic about how great my truck was going to be for me. He also did some repairs on my 7.3 Powerstroke. Sean has decades of experience and stands by his work. You won’t find a more honest diesel mechanic in my opinion (and he gives great advice when you need it!). The communication was great, and the work was timely, professional, and money well spent. It’s great to have a local shop we can rely on. Nathan

Great service, amazing work! Been taking all my vehicles and they never disappoint. Have taken my 03 Cummins three for a power steering pump and a electrical issue and a lift pump and they got it down in a timely manner and did good work told me what was the problem and showed me what failed. They do good honest work.

Sean is the best diesel mechanic in the area. Very professional, upfront, no hidden fees, just an honest business. Replaced the turbo in my 2500 2017 Ram. We priced checked a local competitor and Sean was several thousand less and did a fantastic job. Truck runs great. Won’t take my vehicles anywhere else.

I brought my truck in for an oil change and inspection, and I had an excellent experience. The team communicated clearly throughout the entire process. They even sent videos showing additional issues they found, which I really appreciated. They took the time to explain in detail what needed to be replaced and why, ensuring I fully understood the situation. The communication was outstanding, and everything went smoothly from start to finish. I highly recommend their service.
