I did an oil change for my friend's car and the mechanic was trying to convince me that it is leaking oil and brake fluid. He suggested that the car needs a costly repair (~$1400).
While I don't have a reference for the oil level before this particular oil change, I rechecked the brake fluid level and it was still at MAX level. The last time the brake fluid was changed was a year ago. The only thing that looked suspicious to me was a little bit of engine oil on the engine, but seeing oil somewhere one the engine does not necessarily indicate a leak (e.g. possibly it could have been careless oil change that resulted in spills on engine in the past).
My question is - If a mechanic tries to convince you that a car is leaking something (e.g. oil, break fluid, coolant) and the particular fluid level actually had not changed over several months, is this a good indication that a car actually does not need any repair in the first place?
This is 2008 BMW X3 with gasoline engine.
