Steven was very prompt and professional. He kept me up to date prior to arrival on his timing and whereabouts. Upon arrival, there were some delays in getting the vehicle ready for inspection, however, Steven was very patient courteous. His background of repairing vehicles and his history with welding made me confident that he knew what he was looking for in a rebuilt salvage title vehicle. I hired him through YouMechanic for a pre-purchase inspection. I highly recommend him and will definitely use him for future services.

He seems professional. I paid for the lights to be addressed and they are all still on including a low engine oil light. He said he would return to check it out further after his next appointment but I did not hear back from him. I was told by BMW that the power steering fluid needs to be drained, flushed and refilled. He sucked it out with a hose twice and this will not ensure that the oil that was accidentally placed in there would be completely removed. I am no mechanic but I am going off of what BMW told me. I wanted to get a lot more work done. I want all the lights to be addressed and fixed so I started with the check engine lights to be looked at and not just reset. I want everything to be fixed. Thank you

Luis was very nice. He called and emailed me to let me know he was in route to the preown car inspection everything about the car was written out in his report.

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.
