Another trip to AG Diesel for oil & filters replacement. As always they were up front with pricing, they provided shuttle service back to Vancouver and returned to pick me up when my truck was done. I would highly recommend these folks. Superb service, friendly employees and a fair price. Service: Oil change

I've taken my 2005 Sprinter Mercedes Pleasure Way van to three shops to resolve issues with overheating with no success. Last week it was taken to AG Automotive in Portland. Today I picked it up and drove it to Eugene with no problems. They found a broken exhaust manifold bolt and found the head gasket leaking at the rear of the engine. Expensive repairs but the issues are resolved. I appreciate there thorough inspection and timely repairs. I highly recommend AG Automotive

These guys bent over backwards trying to help us get our car repaired. They taxied my wife around to school early and late. They worked with us to help determine what should be repaired right away and what could safely wait. Special thanks to Shawn!

I was in a tight spot to get a tire patched in order to get to a medical appointment on time. A quick internet search pulled AG Automotive up as the first result and conveniently 5 minutes from the hotel. Kirk took my call and listened to my struggle story and though his schedule was full, he took considerable initiative to fit us in and fix our tire to get my family back on the road with plenty of time to make the appointment! The facility is so clean and organized and all the staff very professional and friendly!

Fantastic service, these guys have fixed issues other mechanics ignored. They regularly tell us like it is and charge reasonable rates. It's not necessarily cheap but it's always done right and stays fixed. As a business we find this much more valuable. Instead of paying to fix something multiple times, these guys do it right the first time. Huge thanks to Kirk and his diesel team!

I live nearby so AG auto is very convenient for me. I've had them do work on two of my older Japanese cars. Both run on gas - they didn't have any problem with that. Shawn was very helpful polite and pleasant to work with. He understood that my budget was tight so he worked with me to diagnose the issues and helped make short and long term maintenance plans. I've been driving one of the cars for about a year now and I have to say that I was so satisfied that I had them take care of the other one recently! Outstanding service!

AG Automotive was very professional servicing my 2004 Dodge 4x4 diesel truck. It broke down on the freeway and I had it towed to AG Auto based on someones recommendation (break down was across town from my home). Kirk was there to greet me at the door, no problem getting into a service bay and work started the next morning. They did a thorough vehicle inspection and kept in touch via my preferred method (text).
I was informed of the estimated costs as inspection and work progressed and we easily agreed on scope of work. Final cost came in slightly below the latest estimate. Diesel trucks are not cheap for parts or labor but for that you expect professional grade work. AG Automotive did not disappoint and I am very happy with the prompt excellent work. Kirk was super easy to work with and his mechanics are great (never met them but their work says everything). Ive had work done by great service departments and incompetent wrenchers.

I am very happy with the service I received. I managed to get a same day appointment, which was great. They also found a patch in the side wall of one of my tires, that no one was aware of, which could have led to some very serious damage. The only thing I would say is maybe don't get your windshield wipers done there. That was a little more spendy than is necessary. But the rest of their prices were very reasonable and the staff were all great!

Avoid! Big time scammers! I've brought my ford there 2 times and they charge you an outrageous diagnosis fee around the 250 to 300 mark. And that's just to diagnose a certain area of the vehicle. Not a full inspection! After they look at it they try to find the most expensive way to fix your truck. The last time I was there the quote for fixing the problem was more than half of what the truck was worth. Ridiculous! Scammers! Beware

Would not recommend this shop. I took a newly purchased truck (03 cummins) to have it looked over. The truck would not come out of park. They charged a hefty $250+ for diag. Recommended the truck have the transmission completely redone quoted over 7K in work alone. I took it to another shop that fixed the shifting problem as well as doing a full tune up on the transmission for $700. They possibly do quality work but not at a price worth finding out.

I just want to thank these guys for repairing some major mechanical mistakes made to my vintage 1945 school bus by another company. The bus had been converted into a 1992 Dodge D350 with a cummins 5.9 engine that had to be replace because of a botched oil change. They were thorough in diagnosing and resolving the problems. I highly recommend this company. Sean The Vintage Tour Bus Co.

This Shop is worse, than going to any dealership, in your worst nightmare, I took My 2014 Ram into these guys, the Oil sending unit went out, I have had a construction business for more than Thirty Years, and have owned, a lot of trucks, so just saying, I have dealt with multiple dealership, and Construction equipment shops, but I never seen anyone, come up with so many charges, when you take your vehicle in for One Item, I ended up paying this Shop over $ 3700.00 and it cost me 8 days rental on a pickup, that was an additional $1400.00 for an oil sending unit and Two batteries, that probably didn't need to be changed anyways. I could go further in detail with this Nightmare experience, but I will leave at this point. I Would Never Take a Vehicle to AG Diesel repair. Beware of The Snake Oil salesman!.

I was traveling in my RV and got an alarm. Went to O'Reilly's where they ran a free diagnostic for me.two glow plugs had failed. Found AG Diesel and went in for repairs. They charged $125 to confirm my diagnosis. Then they were very aggressive about trying to get me to agree to a couple thousand more in PMs and replacing all of the glow plugs. I said no thanks, I'd rather go to my regular Mercedes dealer shop in San Diego.
When I went to my local repair shop they said that not only was NONE of the recommended work needed, but one of the recommended PMs is NEVER done on my vehicle! Keep your hand firmly on your wallet if you use this place.

I paid nearly $400 just for them to look at my vehicle and conduct mild testing. Nothing time consuming or rigorous by any means. I can say that they did a sufficient job with testing however, I was deeply disatisfied with the consultant I worked with to repair my vehicle. In the notes he copied me on, he mistakingly left in a rude comment directed to the technicians regarding my apparent lack of knowledge on vehicle parts.
Here is a copy&paste portion of the sentance from my report, clearly insinuating that I am an ignorant bafoon: ".he does not know what that is.lol." I am appalled at the level of immaturity and unprofessional nature that I experienced from this shop. For the premium you pay, I would accept nothing but professionalism, modesty, and kind communication. Don't visit AG Diesel unless you plan on paying WAY too much for testing and becoming the victim of frivelous insults as the techs and consultants chatter behind your back (or type it out onto paper.lol) - Grow up.

Shawn, thank you so much for the pictures. As you know for the last 7 years I've been working with Northwest Jeep for my diesel maintenance. I wasn't aware of the complete and excellent service that I could get at a shop until I came to AG diesel. Your process is the best I've ever seen made better only by the professionals in your shop. I look forward to getting my diesel repaired and maintained, as it should, through your shop and people, thanks again, Mark

Have a power stroke Diesel. Knew I had some sort of head gasket issue or that it was likely. Took it to AG for a diagnostic. They would not quote me a price over the phone. I know this means expensive, but I needed a good diagnostic. I dropped it off Sunday night. 2 business days later I had not heard from them. I Called and they said it was still in diag. Next day they called at noon and said I needed to authorize level 1 diagnostic, whatever that means.
They said they had too many hours in it for my $120 fee. Said they had 2 or 3 hours already.? Really? You had it for 3 full days! Before I even dropped it off, they knew it was my work truck and that delays meant income loss. Couldn't pick it up until Thursday afternoon. The only reason for 2 stars is I at least have a diagnosis. Very poor business model. On top of that, they want $16000. I can get it done for $5k. Super expensive, slow, cagey with sales tactics. They probably do good work. EIS, or a dealer would be a better choice if you need your truck for business.

I had my 04 powerstroke taken to AG to get a set of injectors done, amongst other things needing repair as well, I dealt mostly with Kirk Erickson who was an absolute pleasure to work with, keeping me updated all throughout the process, my vehicle was completed much quicker then I could have ever asked for and its running great a year later with only general maintenance don't between!

I've been using AG Diesel since 2012 (4+ years) and they really do superior quality work. From general maintenance, to great advice and even half an engine rebuild due to a bad head gasket the parts they choose and the work they do is top notch. I see a lot of comments that they are more expensive. While in some cases that may be true sometimes, for me its "you get what you pay for." My truck is critical to me when pulling 10k+ pounds and breakdowns are not acceptable, I have full confidence after they have worked on my truck something else won't go wrong because of that repair and the original issue won't return.
Whenever I drop my truck off there I have no doubts its in good hands and will get great treatment. Diesel trucks can be expensive to maintain but putting better quality parts in and having people who know what they are doing can really make them last well beyond the 500k marker. They even do custom modification work and in my case support all the custom mods my truck already had, which I love. I will continue to take my 2008 6.4L F250 there in the future.

AG Diesel does a complete diagnosis of everything, it is amazing what can be found wrong that I did not even know about until I took a good look for myself! I appreciate the thorough evaluation of my 2002 Chev pickup, then the repairs are far superior to anywhere else I have taken it to. Thank you guys.
