Service fuel system

Six cylinder front wheel drive automatic 75,000 miles.

I use my car for work and I bought this car six months ago.

It runs beautiful and I do both regular and preventative maintenance.

However, all of my previous cars I changed "fuel filters" usually before recommended mileage or time.

I am advised that this car has a "non serviceable" fuel system with no fuel filter change.

Considering that fuel filters are one of the major reasons for poor fuel economy and as I need to maximize my fuel mileage this concerns me.

Therefore, my question is that "this car" must require a fuel filtering system at some point in time?

IF so, how is serviced? If not, then how is the fuel filtered to maintain performance and good mileage?

Let me clear up a few misconceptions. Fuel filters have basically no effect on fuel mileage at all in modern fuel injector systems or even carburetors for that matter.
The second thing is that vehicle does utilize a non-serviceable fuel filter. The only filter that car has is inside the fuel tank and is not routinely changed as it does not present a problem.
