Robert Grove is literally The Professor of diesel mechanics. Most important he is honest. My name is Dave McGinnis & I stand behind the 5 star review

I contacted Robert via his website after reading his recommendation to diagnose a OBDII port communication error. My car was having a similar problem - particularly with the CA smog check computer.Robert promptly replied to my initial inquiry and we ended up chatting on the phone regarding the particulars of my problem. Because Robert does not perform smog checks he was aware that he would be unable to fix the problem. However, rather than just passing me off to another mechanic, Robert went out of his way and continued to assist diagnosing the problem. Robert placed phone calls on my behalf, performed research online and more. Over more than a week of texting back and forth, Robert provided a ton of insight regarding potential causes of the problem. Additionally, Robert went further out of his way to recommend a local shop and took the time to bring the shop owner up to speed on the issue with my car.Really great experience with a class act professional.

I hired Robert to work on two different trucks, he sent Steven out to install rear brakes on 1 ton pickup and Steven offered to go with me to get truck smog tested. Steven made some adjustments to carburetor which enabled truck to pass test well within range. Robert worked on my other truck, again brake related, and was able to locate a hard to find Hydra-Boost 12v motor. Very pleased with all work performed, highly recommend this company.

Carefull they have no problem charging you 240 for a 20 minute basic oil change

They didnt call me back

The mechanic, Robert, has always showed up on time. He has repaired my generator isues each time at a reasonable rate. Mobile Mechanic is also convenient for myself not to hook up and take trailer to leave at a shop. Thanks Robert.

Called yesterday and they came out the next day and put a new starter in my generator. Great service, definitely would recommend them.

Great experience, great customer service and got the job in a timely manner,

Outstanding service! My RV simply had bad batteries but I was worried about starting it up after a year of sitting. Robert sent his brother Rick out who was and is a true professional. In this day and age, I dont trust many service people. Weve all seen the dateline shows or been victims. My problem was simple and Rick never tried to lead me down any other paths. Rick, thank you also for taking the time to check all the fluids and the tire pressure for me as well as all the helpful tips to keep it running right.You guys are on my speed dial now.

Was in a really bad bind with the generator on our truck. Had less than a day to get it fixed and exhausted all other avenues and means. Came across OC Mobile Mechanics on a google search and called and left a message.Robert was very responsive and was eager to help but didnt have the availability such short notice. He referred me to Guy (gentlemens name) and Guy came through within the hour and was able to remedy the situation that another mechanic couldnt. He solved the problem quickly and now my truck will be back on the road in a timely matter.Many thanks to Robert and Guy for all your help!

Excellent service received from these guys when on vacation and my borrowed vehicle broke down!

Never showed

Awesome site

Dont answer their phone, Voicemail full. 1 star for not being able to communicate them and see if they can help.

Great honest and dependable!

Good people
