Harder, faster said:
Oil and filter... $35-40
Spark plugs... $20-25 (unless platinum then $120)
Air filter... $20-45 (unless its a Honda then double it)
Thats kinda the minimum of what could be needed.. other parts might need to be changed also..
Fuel Filter - ESP NZ Fuel.
Belts - (Cam / Fan / PS).
Radiator Flush.
PS Fluid / Brake Fluid / Auto Trans fluid topped up
Leads (for the plugs) / and the points
If you go to a mechanic say exactly what you expect. If you say you wanna 'service' its a license for them to do what they want.
Say you want an oil change, oil filter, fuel filter & plugs done. Thats probably a good minimum.. I personally would ask for a radiator flush, and for them to check the PS Fluid / Brake Fluid / Auto Trans fluid... I would write that down for them and give it to them when I dropped off the car, and I'd say I want anything else that may need addressing written down for when I collect it. (if they have to write it down they will only write down stuff that NEEDS doing)
Often the air filter can be cleaned and put back in.(sometimes)
