I've noticed I've been getting some bad gas mileage lately. The lines go down pretty quick and I drive it pretty nicely. At 98K miles and I think its time for a nice tune-up. Is there a 100,000 miles service or tune-up? I am thinking to do a tune-up anyways for it. Here is my list I was thinking of changing, and lemme know if you think its a bit over the top.

• Air Filter
• Spark Plugs
• Fuel Filter
• O2 Sensors
• Catalytic Converter
• TCT (needed)
• Valve-Adjustment

•Catalytic Converter
•Fuel Filter

these two parts are made to last the life of the car.
if you dont have the check engine light for o2 sensor or catalytic converter, then you are wasting money. just do the rest.

Well I think the PO (previous owner) used a lower grade of gas which gets me worried about the fuel filter. Im sure its been maintenance abused. Fell into the right hands since I'm coming from BMW
