He did oil change from my car, he doesn't know how to reset it after oil change, the oil change warning is still on and he doesn't know how to reset it to make warning to oil change disappear but, he charged less money, now I have to go to real mechanic to have my car reset so that warning sign go away

They are real experts. I've been to multiple repair shops to fix my car, but they didn't make it in the end, they didn't know what the problems were exactly. The price is also affordable. If you live near Diamond Bar, I would like to recommend it.

why are you going anywhere else? after a cross-country trip, i took my vehicle to a chain service place for an oil change. a while later, i started to see oil drips in my parking spot. i called diamond bar auto and they had me come right over. the mechanic had a nose around under the hood and under the chassis, showed me the problem, reassured me that i could manage it until i got home to my regular shop, and declined any payment for his time. honest, kind, and professional. i promise you’re not getting this kind of service from the chain places.Service: General repairs & maintenance

Great place to get oil changes or fix minor tire damages from nails! Wait time varies, Saturday is their busiest as they close 3 PM (Lunchbreak 12-1)

Affordable rates, no up sell, $50 synthetic oil change, quick, small waiting area, heavy Korean English accent but was able to converse. Honest and they didn't try to push any service onto me. Found my mechanic!

They are very honest. Thought I had major oil leak turned out last place ( pep boys) did not put washer back on oil plug. With oil all over the place when I first took it to Choi he thought maybe needed to change all the gaskets turns out it was the plug. Huge savings others might of stuck to replacing all gaskets.
