Excessive oil consumption
I have a 2000 Excursion, with 216000 mileS on the V10 motor.
When I got it a few months ago I had to put 4 quarts in it before I test drove it. Sticker on window showed it had 3200 miles on it since last oil change.
During initial maintenance of changing all fluids I also put a new motorcraft pcv valve in.
Once I got it home I did a full oil and filter change with amsoil 5w-30.
Drove it about 3000 miles and checked oil level. 4 quarts low!!
I park on concrete and engine has zero external leaks. There is no sign of oil in coolant or any sign of oil being spit out tail pipe.
Anyone have any clues as to where I should be looking for my disappearing oil?
I just did an oil change with high mileage 5w-20 synthetic oil, with hopes it might help.
Oil pressure is good, and engine purrs like a kitten.

Excessive oil consumption
Check the hose on the drivers side, one of my 2000 truck had a bad fitting letting it air get pulled in causing low vacuum so oil would go up the pcv system.
Also when the truck is warm remove the oil fill cap and have someone put it in gear and with the brakes on step on the gas. If you get vapor coming out the oil hole you have compression blow by and there is only one way to fix that, new motor. That's the first thing I did before I bought to a high mileage F150 a few months ago.

Thanks I will do that.
Just so happens I have a new hose that goes on drivers side. Ordered a "PCV" hose off an oem ebay dealer and got the breather hose instead.
Think if I get blow by I will just keep adding cheap oil until I have to buy a remanufactured one or just rebuild one myself while I limp this motor along.

I could deal with that.... .5 quarts per 1000 miles. Mine uses over double that. Seems to be a little too much.

Normal
Mine (2007 E350 V10) is the same- about a quart every 1,000. I've tried every oil known to man- high dollar racing synthetics, semi synthetics, standard oil of every brand, generic, everything. It's always the exact same consumption when I use 5w20 (as indicated by the owners manual and the fill cap).
However, whenever I run 5w30 the consumption is greatly reduced. I think Ford had good reason(s) to specify 5w20, so I'm sticking with that.
This forum is full of this exact conversation. The consensus is two things, 1. Check/replace PCV and its hose, and 2. A quart per 1,000 is normal.

Both of my 2000 V10s had 5W-30 on the cap and that's what I used the whole time I had them, I know a bulletin came out latter but I still used Mobile 1 5-30.

No issues with my PCV vent hose or the valve cover bushing it goes to.
PCV hose that goes to the PCV valve though is heat cracked and may be causing the issue.
Cannot seem to find an OEM replacement for it. All replacements seem to have insulation on them, so I'm not sure they will fit.
Anyone have a oem part number for a 2000 V10 excursion pcv to intake hose. Even the part # that is $60 or so that includes the heater hoses does not look right.

Foam insulation is right for the PCV hoses on the passenger side. The PCV hoses were changed in the 04' MY and are different from the earlier ones.
This is a pic of an 03'.
All I use in V10s now is 5w30 oil, but I have been going to a 0w30 in the winter.The modulars have specd 5w30 for years. Consumption can vary quite a bit depending on the vehicle and type of driving. If memory serves me right Ford thinks a quart consumption in 700-800 miles is acceptable. I think that is too much consumption but just saying what Ford thinks.
You really need to learn to check your oil level more often. One of these times you will get too low and end up having to drop a long block into the truck. With such a physically large engine with a rather small 6 quart pan, there is not much room for error when oil is 3 or 4 quarts low.

That is great info.
I have 2 excursions and I just bought this one. 1st one has a V10 also. Same year, 2000. It has 4000 miles since last oil change and only used 1/2 quart.
That photo does not seem to show the heater hoses going to the PCV valve, as mine does. Did they delete those in 04?

Sounds like you have a heated PCV valve. Do you have EGR on your Ex? That pictures is from an 03' and it does not have a heated PCV valve. I did not know that Ford put heated PCV valves on the V10s but there have been changes over the years and some areas get different options depending on climate and state/local law.
My dads old 03' (in the pic) used about 2 quarts ever 3k miles or so when he was driving it normally back and forth to work.(5 miles each way and short trips) But he would take it on vacation on a long 1k miles trip laoded and it would not use any oil. We both figured the short trips we the cause for the increased consumption. My 04' does not even use 1/2 a quart in 3000miles.
