Oscar has always taken very good care of me on either my 6.0 diesel or my 6.2 gas Ford F-250s. Very knowledgeable and is always willing to lend his mind. Very Affordable and Honest which is getting hard to find these days! Just recently bought a new 2014 F-250 and alignment/tire shops were telling me I needed a whole front end @$1400-1800.00+. Took it to Oscar, he put it on a lift and it ended up just needing shocks and stabilizer which is common for these trucks. Around $300 total. Awesome family owned and operated business and I always recommend them whenever I can!

Good hard working honest people. Fair prices.

Great service! They were great about talking through my trucks issues with me.

Brought my truck in cuz it was knocking they said they know what it is, they had it for 6 months. supposedly fixed it. I get my truck back and it still makes the same knocking noise. Now they said theres no way to know why its knocking. But they charged me $3500 for something they never fixed. Worst mechanics in the whole country. Dont trust them at all. Id put negative 5 stars if I could.

They got to my trk right away and got it fixed . I found them to be very knowledgeable. Very pleased, trk runs great .definitely call on them again !

Loved my experience at Muniz diesel. Brought my 6.0 Powerstroke in for a crank no start, they had it fixed in less than a day.The truck had spent 4 weeks at another shop in okc before I sent it to Muniz. Highly recommend them!

Brought my 02 f250 in to fix an oil leak. They didnt repair the leak which was coming from the hpop plug. They instead charged us for some o ring on the oil cooler, and said it was fixed. I didnt even leave their parking area before I noticed it was still leaking profusely. It was in their possession for 6 days. I took it home and replaced the hpop myself. If you have the motivation, youd be better off fixing it yourself like I did. If 0 stars was an option, Id pick that.

Had the truck there for 6 days. Got it back they said it was fixed mind you they only charged me $80 but it was not fixed at all. They said it was just an o-ring and when we finally got it fixed it was a complete oil pump.Dont know if they were busy or just scared to fix it right. But definitely wasnt happy with my outcome. We dropped it off from an oil leak and we picked it up with a puddle of oil under it

Oscar and his family run a great business. Very fairly priced, and honestly through doing business with him I can say we’ve become good friends. I refer as many people as I can in that part of Okc over to him for diesel work.As another automotive professional… I admire his willingness to want to do right by his customers. I definitely recommend him, Plus they are starting to use BG products which is huge in my book!

Very Powerstroke 6.0 knowledgeable.

Bad we tooked our van to get it fix n week later idk wat but motor stop working n we pay around 3000

Well
