Hi everyone,
I recently asked my wife to bring in the car (2004) for an oil change. I let my wife ask for the best oil (Castrol syntec 5w40). After oil change, when I test drive, I started to feel some shaky/rough when the car is stopped with D gear. It was perfect before oil change (last oil change was 8 months ago, also with castrol syntec at a different dealer). Also, the engine starts to sound just slightly different louder (a little bit like those race car engines...). I do admit that the acceleration may have improved just a bit also.
I suspect something has gone wrong, but I couldn't tell. Since we have owned this car for just about half a year, so I really have no clue about if this is normal or not. We liked the car very much, but we are weary of what we may need to invest for repair down the road.
The dealership said that they did nothing other than oil change. Also, they tried to persuade my wife to pay extra $20 for tire rotation. If I were there, I would just point out and demand that they should do it for free. They want to rip off people who don't know much, like most of other dealers.
Thanks for any advice in advance!
