MD80 flight crew advises of discrepancy between minimum altitudes at fuelr intersection on paradise arrival (8000 ft MSL) vice ILS runway 25L IAP (7000 ft MSL). Advises FMS displayed the lower value prior to clearance for the ILS approach.

Narrative:
On the paradise 4 arrival to lax; the FMS box selects 7000 ft for fuelr while on the PDZ4 arrival shows 8000 ft or above. On the runway 25L approach chart fuelr is shown at 7000 ft and on the civet arrival fuelr is 7000 ft as well. We had no problem with the approach; just wanted to pass the information along.callback conversation with reporter revealed the following information: the reporter advised that it is necessary to program three segments to accomplish an arrival based on the paradise STAR. The STAR must be selected; the runway transition must be selected and the runway/ILS must be selected. In the case of the hardware on this MD80 this resulted in the lower altitude being programmed and displayed at fuelr even when accomplished well prior to the procedure actually being flown. Reporter feels that the higher altitude should be displayed until such time as the flight is cleared for the ILS itself to preclude the possibility of descending below 8000 ft MSL as required by the arrival route transition.

Title: MD80 FLT CREW ADVISES OF DISCREPANCY BETWEEN MINIMUM ALTS AT FUELR INTERSECTION ON PARADISE ARRIVAL (8000 FT MSL) VICE ILS RWY 25L IAP (7000 FT MSL). ADVISES FMS DISPLAYED THE LOWER VALUE PRIOR TO CLRNC FOR THE ILS APCH.
Narrative: ON THE PARADISE 4 ARR TO LAX; THE FMS BOX SELECTS 7000 FT FOR FUELR WHILE ON THE PDZ4 ARR SHOWS 8000 FT OR ABOVE. ON THE RWY 25L APCH CHART FUELR IS SHOWN AT 7000 FT AND ON THE CIVET ARR FUELR IS 7000 FT AS WELL. WE HAD NO PROBLEM WITH THE APCH; JUST WANTED TO PASS THE INFO ALONG.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE REPORTER ADVISED THAT IT IS NECESSARY TO PROGRAM THREE SEGMENTS TO ACCOMPLISH AN ARRIVAL BASED ON THE PARADISE STAR. THE STAR MUST BE SELECTED; THE RWY TRANSITION MUST BE SELECTED AND THE RWY/ILS MUST BE SELECTED. IN THE CASE OF THE HARDWARE ON THIS MD80 THIS RESULTED IN THE LOWER ALTITUDE BEING PROGRAMMED AND DISPLAYED AT FUELR EVEN WHEN ACCOMPLISHED WELL PRIOR TO THE PROCEDURE ACTUALLY BEING FLOWN. RPTR FEELS THAT THE HIGHER ALTITUDE SHOULD BE DISPLAYED UNTIL SUCH TIME AS THE FLT IS CLEARED FOR THE ILS ITSELF TO PRECLUDE THE POSSIBILITY OF DESCENDING BELOW 8000 FT MSL AS REQUIRED BY THE ARRIVAL ROUTE TRANSITION.
