Suggestions for Service at 34k
 

I'm dropping my car off at mazda dealership service tomorrow just to have them check on the basics and do an oil change, etc. This will be the first real check-up that I've had since I bought the car.

That being said, any suggestions on what I should have them replace/look at/test?

Right now, I'm getting new plugs, an optima red top put in, oil change, hopefully K&N filters, and I'm having them check my OMP because I don't think I'm burning as much oil as I should be honestly. Also, I'll have them check on the status of any recalls/PCM flashess and hopefully replace the gasket in the tail lights.

Any other thoughts that could be beneficial at 34k? Fluids, etc?

Ahh Those God Dam taillight gaskets...
I would also have them look at the drive belt if they haven't done so in the past.
Have them look at the fuel filter/lines/hoses if that hasn't been done
Have them lube all the hinges/latches( you could also do this might save money)
I would also have them replace/ inspect the rear diff. fluid and trans fluid.
Cabin air filter could be replaced if you haven't done that yet (you could also do this to save money)
Coolant might also be something to have them check/flush if you haven't done so.

Other then what you said you would do and my couple extra I think you should be ok. But a lot of the easy stuff you could do yourself- save a few bucks.

Good Luck
