Open the full vehicle complaint log (all categories)CONSISTENT ISSUE WITH FUEL IN OIL. LATEST REPORT FROM THE OIL ANALYSIS HAVE 4.5 PERCENT FUEL IN OIL. DROPPING OIL IGNITION POINT TO 285 DEGREES. ISSUE OCCURS DURING NORMAL VEHICLE USE.
EXTREME FUEL DILUTION IN THE OIL. LIKELY FROM LEAKING HIGH PRESSURE FUEL PUMP. I HAVE ATTACHED THE RESULTS FROM OIL ANALYSIS AT 1860 MILES. THE TEST ONLY INDICATES THAT FUEL DILUTION IS ABOVE 5%, WHICH ITSELF LEADS TO SEVERE OIL DEGRADATION. WHEN I CHANGED THE OIL, I DRAINED 7.5 QUARTS OUT OF AN ENGINE WITH A 6.2 QUART CAPACITY. THIS WOULD INDICATE A 21% FUEL DILUTION, NOT INCLUDING FUEL THAT HAS EVAPORATED FROM THE CRANKCASE AND RETURNED TO THE COMBUSTION CHAMBER VIA THE PCV SYSTEM. IF I ABIDED BY THE MANUAL'S RECOMMENDED OIL CHANGE INTERVAL, I HAVE LITTLE DOUBT THE ENGINE WOULD EVENTUALLY CATCH FIRE, BASED ON THE RESULTS OF SEVERAL TESTS COMPARING FUEL DILUTION TO AN OIL'S FLASHPOINT. AFTER CHANGING THE OIL, IT SMELLED FINE FOR THE FIRST 20 MILES OR SO. AFTER THAT, THE OIL BEGAN TO FEEL OF GASOLINE AGAIN. AFTER GOING THROUGH FORD'S SERVICE MANUALS, I HAVE ASCERTAINED THAT THE PROBLEM MUST LIE IN THE HIGH PRESSURE FUEL PUMP. IT RUNS OFF THE CAMSHAFT, WHERE LEAKING FUEL COULD THEN MAKE IT INTO THE ENGINE AND MIX WITH OIL. THERE WOULD BE NO WARNING OR INDICATION, BESIDES RISING OIL LEVELS ACCOMPANIED BY THE SMELL OF GASOLINE IN THE OIL. IT DOES NOT MAKE ME HAPPY THAT MY DEALER IS NOT TAKING THIS ISSUE SERIOUSLY, ESPECIALLY BECAUSE A FUEL LEAK OF ANY KIND ALWAYS HAS THE POTENTIAL TO LEAD TO A FIRE OR EXPLOSION IN THE HOT ENGINE BAY. I PAID OVER $40K FOR THIS TRUCK, AND SHOULD NOT HAVE TO CHANGE THE OIL EVERY 500 MILES TO KEEP IT FROM SELF DESTRUCTING. THANK YOU FOR YOUR HELP IN THE RESOLUTION OF THIS ISSUE. I DON'T FEEL SAFE DRIVING MY FAMILY IN THIS VEHICLE, AND FORD HAS REPEATEDLY CHOSEN NOT TO ADDRESS THE ISSUE. I FIRST DETECTED THE ISSUE ON OCTOBER 20TH, BUT I HAVE NO DOUBT THAT IT HAS BEEN GOING ON SINCE THE TRUCK ROLLED OFF THE ASSEMBLY LINE. I PURCHASED THE VEHICLE ON AUGUST 30TH OF THIS YEAR.
