Noe went above and beyond the service I requested (oil change and tire rotation). He gave my car a thorough inspection, and took detailed images of several areas I need to put additional maintenance into. He was fast too - in and out in less than an hour! Thank you Noe for an excellent job!

Jeff provided me with great service. He arrived on-time (actually he was early, which was even better). He listened to my complaint and quickly went about assessing the situation. After a thorough inspection/diagnosis he explained what the problem was and offered a solution. He made several suggestions for future work that I need to keep an eye on. His written/recorded report was comprehensive and professional. He took the time to answer all of my questions and made several helpful comments regarding my concerns. Overall, I was very pleased with Jeff's knowledge and professionalism. Whenever I need a mechanic in the future, I will most likely call on him. A Satisfied Customer, RJH (Bob)

All about Differential/Gear Oil Replacement

Differential oil is a type of oil. Cars have a gearbox connecting the two axles. This gearbox is responsible for the conversion of engine power and its transmission to the wheels, allowing them to turn at varying speeds. This part of the car is called the differential, and lubrication is needed for it to function properly. Differential fluid, also called differential oil, provides the lubrication and cooling of the car’s differential. The fluid is there to protect the gears’ metal surfaces from friction, and to prevent overheating and burning.
