Advice for Know-Nothing with an Aging Mazda 6 | Routine Service Advice

Hello!

I am the owner of a 2009 Mazda 6 with 112,446 miles on it. I've owned it for 9 years and it has always been reliable. The only thing I notice being "wrong" with it is that it runs a little loud when idle. Nothing alarming but it is loud. I've always changed the oil regularly and drive it only around 100 miles a month tops.

I recently went in for an oil change to Valvoline. (I usually go to a local mechanic.)

Obviously Valvoline went crazy with the recommneded upcharges.

They recommended (see image atachement for deatils):

Power Steering Service
Automatic Transmission Service
Radiator Service
Serpentine Belt Service
12 Mo. Fuel Treatment
Fuel System Cleaning
Air Condition Service

To my knowledge, I've never had any of these services performed on my vehicle.

I'm pretty sure they just try to sell you whatever, but I am also aware my car is aging and I'd like to extend its functional life as long as possible.

I'm coming to you for help in a) determining if/when these services are truely necessary and b) how to prioritize them. I don't want to drop hundereds at once to service this old ride unless I have to :)

Thanks in advance for helping me learn how to care for my old car :)
