Every time I come to any terrible s I'm told my car has all these leaks and problems.. Then when I take my car to my trusted mechanic of 14 years.. He tells me they are crazy and the problems don't exist. And the up selling drives me nuts! If synthetic oil is better for the heat.. Why not make that the standard since we live in the desert? Does it really cost $20 extra for that oil ? I'm disappointed in the business practices here and always telling me my car is broke or leaking.. When it's really not.. My rating is purely in business ethics
