Question about 2002 Ford F150 Regular Cab
2002 Ford F150 4x4, 5.4L engine. Truck has 107000 miles and never lost a drop of oil. HAd spark plugs changed and all fluids changed front to back of truck to insure a continued and long vehicle life. 5 weeks later discovered I was 5 quarts low on engine oil, with no alarm or idiot light. Re-filled and the trend is the same, still loosing oil at an alarming rate. Always used Mobil 5w20 synthetic oil. No oil leaks visible, no oil on undercarriage or in driveway. tailpipe doesnot show black. No smoke at startup. No power loss. Any Ideas? Can the catalatic converter be atomizing the oil eliminating any residue out of the tailpipe?
This is certainly one of the strangest things I have ever heard as a mechanic. . This almost sounds like some one is playing a game of letting your oil out this vehicle. With no visible leaks no burning smell of oil. However I would recommend that you check the coolant in the radiator and see if the oil is in the coolant. (If they are mixing together) If they are mixing the coolant should have a milky look to it, creamish white. If its good then the only other logical explanation is that the vehicle i s burning alot of oil, but if that was true you would see a grayish blue smoke from tail pipe. If you are 100% sure they are no oil leaks on this vehicle, then this problem is surely strange. Check coolant and get back to me. Good Luck

I have an f150 super crew cab 2002 and I have these same oil problems and have not leaks. I also in the last two years to different sparks plug blow right out the engine and the coil spring were blowed apart. Went to chang my spark plugs July 2, 2009 the No.5 spark plug had oil on it and the No.1 which was the last one to blow out the engine last year went to replace it pulled out the old one and can't get the one new in it's if it's stripped all of the sudden.I also am not blowing blue or gray smoke and just passed emission.

I have a 2005 f-150 supercab 4x4 lariat with 5.4...46,000 miles on it. I change my oil every 3,000 miles like clock work. I just took my truck to the dealer. The truck burnt 2.50 quarts in 1,000 miles. Ford ran a leak down test and compression test... it was all over the place in the readings needless to say they are looking to replace the motor with a long block....but they have to tear it down and have a Ford inspector look at it. I just dumped a 2004 f-250 4x4 6.0 diesel with 40,000 miles...blown heads,turbo,abs,heater core, upper and lower ball joints, bead plates, on and on. My opinoin of Ford now is they ****.

I had a 97 f150 with a 5.4l motor. It blew the spark plugs out two different times. One blew clear out of the motor. I was able to rethread the plugs into the head and I got 327,000 miles out of it until the next one blew out and I replaced the motor. Toward the end I was adding a quart of oil about every 1000 miles or so and figured it was burning off but I never saw any evidence of it. I would like to know what causes this oil problem. no worries I have a 04 chevy for a year now with no problem with anything whatsoever.
