Should we trust the recommendation by auto service?
I have been doing auto service in Active Green cross for a while, for every oil change, they always recommend me to do different service. And I spent couple of hundreds dollar for the engine light but it did not get solved - first they changed the oxygen sensor, after month the light come back again...
Now I will never go there again as they always ask me to do unnecessary service, even change the park which is working fine. Like dealer, charge $100 for a simple inspection, they change a part. If still problem with the car, tell you there is another problem and ask you to change another parts..
So find a trusted auto service is important, by my experience, I donot trust dealer and chained auto service such as Active green cross...
