Hello all,

I'm a person who tries to maintain my vehicle, after all I brought it brand new and spent what is in my opinion a good deal of money and plan to keep the car long term.

I'm no expert on cars but I know some. Before buying a brand new car I never took previous cars to dealers for service but this time around convinced myself it was the correct option.

I just don't want to be taken advantage of, which I have a certain couple scenarios in mind that left a bad taste in my mouth with a particular dealer service center so I won't be returning there.

Anyway, can someone point me into the correct direction about maintenance schedule? For example with oil changes, I was going down to 15% as the sticker would say but other dealerships say 5-7k per oil change regardless of oil percent. One dealership said I was due for tranny fluid replace @ 50k while another recommends every 30k. Looking online some dealerships recommend to replace spark plugs @ every 30k while the current dealership I've been taking it to says around 90-105k.

It seems like the maintenance minder only shows oil changes and tire rotations for me, I'm at about 70k right now. I was told if the system is reset in-between needing an additional service It won't reappear (if that makes sense)

Anyway, what is the best intervals in your opinion for
*Transmission service (fluid drain and replace as from what I understand never flush)
*Break fluid service
*Coolant replace
*Spark plugs replace

Thank you for reading. I just wanted some honest opinions from trusted folk who most likely work on their own card vs salesmen.
