Just came back from the dealership today after an oil change and tire rotation. During the time I was there, the salesman tried to upsell me on the 30K service with premium oil conditioner, fuel additive cleaner, crankcase cleaning service, battery cleaning service, brake fluid exchange service and A/C odor treatment service which costs close to $1000. I declined all those services but the guy did mention my brake fluid is a little dirty, The vehicle is 27 months old and has 22,200 miles. I checked the owner's manual and it says to inspect the fluid. I guess my question is, when is it recommended to change it. Should I receive a second opinion? I have no intention of returning back to the dealership.
