Ford F-150 - 1997-2003 :: 1999 - 1 To 2 Gallons Of Oil Every 150 - 200 Miles?
Feb 6, 2013
I am having a huge issue with my 1999 ford f-250 super duty 7.3 diesel. I am goin thru 1-2 gallons of oil every 150-200 miles I drive. I can can smell oil thru the exhaust when its running. There is a layer of oil "residue" on the engine. A buddy of mine suggested that I might have a broken O-ring on a fuel injector.....is there ANY way of testing that before tearing everything apart to get to the valve covers??
There is NO oil on the ground when left parked for a few days. I can NOT see any significant area in the engine compartment where it is leaking....

2000 f-350 cc srw 4x4 lb. Added a 4inch diamond eye and sct programmer 2 years ago. When I bought it 4 years ago no oil leaks. Last year had a small leak 1 qt every 3000mi. Went camping tuesday when we got there 1 Gallon low and a camper covered in oil. On the way home used 2 more gallons and topped it off with another gallon before parking. Checked the dip stick tube connection no luck.
Cleaned top off with simple green and garden hose finding the drain hole in the back clogged and valley full of oil. Got the front half clean and checked for leaks and found none front valley is still clean.
Had the wife run it up to 2000 rpm for a minute when she let off the throttle and when it slowed got a 3 second stream of oil from the cover at the back of the oil pan. CEL came on code 1280 found oil in the ICP plug ( will order that with orings and tool for hpop for preventative). Removed the air crossover to the turbo and still oil in the back half cleaned it all out and drying now.
Checked the plugs at the back of the engine and they are clean. Where should I look for the leak to be at?

How many miles and/or gallons are available when one is down to the last "blip" of the 10 blips showing the gas level?
I have gotten anywhere from 79 to 92 miles in the highest blip. I have gotten 43-50 miles on the second to last blip. Today I got 30 miles out of the last blip and it took a hair over 9 gallons to fill up the tank. I feared that I was cutting it pretty close.
I was just wondering how many miles I might expect to get out of that last blip. My normal MPG is 42-47 MPG. But the MPG really seems to go down as one gets towards the lower blips. Is there some kind of warning when one gets really low?

From all I can see, the fuel tank capacity on my '12 should be 17.5 gallons.
As I finish up a trip with it, I know I've "pushed the envelope" as far as fuel range is according to the guage/computer. I get the warning that I need to refuel and that I have 50 miles to empty, but I've driven 40 miles into that last range before refueling, and only been able to put 14 or so gallons into the tank.
My question is: If I were to drive until it literally runs out of gas, then fill it, would the guage/computer recalibrate or do I need to install a new fuel sensor?
I get the warning as the guage indicates just under 1/4 tank remaining, and I have yet to run it until the guage indicates that it's actually on empty (family and dog are with me so risking it is currently out). I'm hoping that the guage itself knows what the real deal is and that the computer is just not with it.... OH, FWIW full is EXACTLY on the "full" line and not over as in my Kia.

Tranny just started slipping a couple of weeks ago, only occasionally. Seems to be between 2nd and 3rd. any chance a fluid change will work? I don't have have the money right now for a new or rebuilt and I am far from mechanically inclined to do the work myself. 2000 F150 62K org Miles....

2003 F 150. 5.4 motor. 4x4. 270,000 miles. Climate control.
The A/C is ice cold.. For the first 12-15 miles, and then it shuts off and is warm.
I had it recharged at the shop just to be sure. When it works, it blows out the vent at approx. 42 degrees.. nice and cold.
This problem happens every time. Turning the climate control off and then back on doesn't work.
Shutting the truck off and then back on doesn't work. Wait a while.. Not quite sure how long, but the next time I drive it, it will work again. For about 12-15 miles and then blows warm again.
A bit of funky , moist smell to it when it blows warm.. Typical A/C smell I think.. The box could prob use a cleaning.

I have a 1997 F150 4 x 4 with the 5.4 overdrive transmission. When I accelerate from a stop I can feel the slip of the transmission until I reach exactly 35 miles an hour. Above 35 seems to be normal and have plenty of torque.
The funny thing about this is I have had a 2001 Windstar same 35 miles an hour. I have also owned a 1997 Ford Explorer with this exact same issue. Three different motor and trans combination that will not lock up until you reach 35 miles an hour.
The truck has 213,000 I have replaced all coils fuel filters catalytic converter and torque converter. Have exterior tranny cooler. engine runs good and strong. And no code I have a reader.

I have a 2001 f150 7700 edition. The truck has 118,000 miles and i've owned it for the past three years, the trucks great and really reliable. I drive the truck every day 50 miles to my college and about two weeks ago my truck started shaking . I had just got off the highway and made it to a stop sign. I then took off and when I hit about 30 miles an hour the truck started shaking but when I hit 40 it stopped.
I said whatever and ignored it. now it does it pretty much anytime I go past 30 miles in hour. My tranny shifts good. I checked the fluid and it was normal. smelt it and it didn't smell burnt or anything still pretty red. Some days its worse then others. Also, no engine lights, tranny lights, no obvious lose parts, tires are good. It only shakes when I give it gas. I let off the gas at 80mph and it doesn't shake at all. Which is why I'm confused.

2003 F-150 Supercrew w/4.6 V-8, 2-wheel drive, 219,000 miles and very well maintained. I'm getting an intermittent overheat condition that I can't figure out. Coolant level is good and I just replaced the thermostat. My OBDII app showed it running at a constant 207 degrees (195 thermostat) after the thermostat. Appears to have good pressure at the cap. It ran great for 30 minutes at idle and then did fine for a five mile test drive.
The next day in the morning it overheated within 3 miles of the house (heat was on) and you could smell it. Pulled over and let it sit for 20 minutes and started back up and it stayed constant at 207 all the way to work (11 miles). It sat at work for about 7 hours and ran great all the way home (without heat, with heat, with air cond). Then this morning it did it again, overheating about 3 miles from home. This time I pulled over and shut it off for about three minutes. Turned the key on without starting and the temp was already dropping again. So I started it up and it continued to drop down so I drove to work with no more issues. This afternoon again went home and it never overheated.
I'm expecting it to overheat again in the morning. I'm gonna go live on the OBDII for temps during the drive tomorrow.

I have a 1998 Ford F150 4.6L Triton V8 with the FX4 package. As of recent I have noticed my truck tends to idle roughly every so often that I start it up and after longer trips but will run fine once I get going. I take care of my truck like its my baby. I've done everything to it that I can without getting into the engine such as replacing spark plugs, wires, KN air filter, new ignition coil packs, change oil every 5000 with best products, etc the basic tune up stuff every one should do. This truck only has 118,xxx miles on it as it sat in a barn for around 4 or 5 years due to the previous owner being in the military.
I have been trying to search for the cause of this problem but cannot exactly seem to pinpoint it myself. One unusual thing I've noticed also is that when I run the air either hot or cold when my RPM's get high, when I go up hills or punch it, the air switches from vent to dashboard(defrost). I talked to someone who said this was most likely a vacuum leak. Maybe there is a correlation between the two? I'm not exactly sure. I read online my idling problems may be from a cracked PCV elbow? I cleaned out the EGR valve also about two months ago to see if that work. I am willing to try anything myself as long as it doesn't involve tearing the motor apart!

I just bought a 2000 expedition 4.6 EB.. Just like an f150 same principles apply. Here's the issue, it has 284k miles. I realize its probably just tired and worn out but it just doesn't have any torque it seems. If you punch it above 60 it barely creeps up the speedo, my 00 f150 4wd with the same engine about same mileage was way stronger. My only code currently is P1151 dealing with the o2. Plugs are new coils and most all else is probably old. Just wondering if something is wrong and not throwing code or if its just a tired engine in a heavy vehicle?

Was thinking it was around 38 gallons but I'm thinking it's less than that. I have a 1999 Super Duty V10 with the long bed.

I have a 2001 f250 with the 5.4. from what I have read i should have the 38 gallon tank. i have been really questioning the accuracy of my fuel gauge on empty with the light on 25 gallons and the fuel pump will click off and after i drive i can park and my fuel gauge will read lower than what it was when i pulled into the driveway with. me and the wife went driving yesterday and we pulled back into the driveway on half a tank this morning I went to go run some errands and when i started the truck the gauge was almost on a quarter of a tank my driveway is flat and after driving for about 35 minutes the gauge was still in the same spot and did not move up nor down.
I have a locking gas cap cover so i know someone is not taking gas out. I have changed the fuel filter and tried numerous different fuel system cleaners to try and see if maybe the contacts on the float in the tank are dirty nothing has changed or gotten any better. I have checked the wire harness from the top of the tank and followed it up under the hood and found no drop in voltage or cracked or damaged wires. I checked with my multi-meter I used my fluke meter not some cheap one. Don't know if the gauge is reading less or more from getting gas i am thinking it is showing less than what is in the tank. What could be my problem?

I have had this truck for about 3 weeks now, and twice on hot days (95F) it wouldn't start. Both times I had not driven the truck that day, so this would be a "cold start." No "idiot lights" came on to give me any indications. The Haynes Manual does me no good on this. Other than this issue, the truck runs and drives great.

I am losing a small amount of antifreeze, about a cup every thousand miles, so I have to consistently add antifreeze. When i remove the oil fill cap, I have a small orange ring leading me to assume the loss is into the engine.
Dealer pressure tested system and told me everything was good, could not find a problem, which I think is likely not correct. How to proceed?

I made the plunge and picked up a 02 f250 with 7.3. 200000 miles runs and shifts smooth. Just a little rust issues I need to fix before they get bad. Figured I'd stop in ....

Diesel smell in cab. 2000 F350 7.3 158K on the clock. Just noticed it 3 days ago. Been meaning to address the passenger side fuel line clamp issue. Learned about that one here. Gonna tear the stuff out to get at that one Tuesday. Replacing the clamp. Hope the fuel line is not already compromised.

Just joined today, I have a 2003 550 7.3. New HPOP, 3 new injectors, new seals on others, new fuel pressure regulator, new fuel pump, sending unit mod to eliminate filters. 733 HPOP pressure, 65 fuel pressure at idle. Truck runs out of fuel pressure after its warmed up and driven about 20 miles. Haven't checked voltage at pump while driving. I had taken it to a seasoned tech of 20 years and he had replaced HPOP and 2 injectors and it does start better but problem is still there.

I had my transmission fluid changed because it was leaking from the pan. I did the job myself but called VW to confirm how much fluid I needed. They told me the wrong amount but we realized that after we did the job.. they did the repair for a huge discount and I only paid $200 bucks for the work for them to "fix" what they messed up. Volkswagen did it and I got the car serviced at the end of April basically. now its the first week of July and under 90 days since the car was service and now it is shifting hard between 2nd and 3rd gear or 35 miles to 45 miles per hour. The car isn't throwing a transmission code I have a vag com and there is no code coming up on that.

My 1999 5.4l runs great then after driving about 20 minutes, surges & stalls if you try to accelerate. Then the idle surges from 600 to 1500 (back and forth). Connected a fuel pressure gauge, and it shows 30 then drops to near 0 then bounces back to 30 then near 0, then back to 30 etc. No codes are reporting. What to check? Let it cool down, process repeats. Has new fuel pump & filter.
