I will never go to this shop ever again.
I had a n oil change and their technician didnt put the dipstick all the way in (if at all) and after today all of sudden there was burning smell coming from the vent.
When i open the hood, there was oil spill all over. Now even ive put back the stick, the burning smell still comes back after some period of driving. I guess it's because of the oil stuck on the engine and when the engine turns hot, the oil start to burn...
