How often do I need my oil changed?

Certain models of vehicles recommend an oil change with full synthetic oil once a year. I personally recommend every 6000 miles or twice a year to keep you car running at optimal.

What kind of oil do you use?

We use the factory recommended oil no matter the mileage, even if the vehicle has a lot of miles its the same weight but for high mileage. 

When can I do the transmission fluid change?

The majority of vehicles transmission fluid need to be changed every thirty thousand miles.

Why does my check engine light turn on?

The check engine light turns on for a number of reasons, something could be wrong in the engine/ transmission or minor like the evap system, I recommend getting it to the shop and perform the appropriate diagnostic.

My air conditioning isn't working, can i just add freon?

To add freon to the system we must first find out how much is in the system and what the factory recommends, for that we would have to recover and charge the system to the appropriate levels, a system that is overcharged with freon could very well also cause problems.


Mr. Arias is an amazing mechanic! I highly recommend him to anyone searching for an extremely knowledgeable, fair & excellent professional who can repair your foreign automobile. I won’t go to anyone else. He provides exceptional customer service and goes beyond your expectations. He is patient and will take the time to explain & answer your questions, but he is quick with the turn around time of repairing your car. I struggled trying to find a good mechanic and I wouldn’t go to any one else for my car. He understands BMW’s better than the car dealer itself. Thank you Mr. Arias 🙏.
