I just bought a V10 Excursion a couple months ago and it is burning about a quart every 1500 miles which seems a little high but not excessive. It has 95k miles on it. I was wondering what is normal for these engines. I am use to my Ranger burning less than a quart in 10,000 miles but it is a lot smaller engine. My old 7.3L IDI Diesel burned about the same amount of oil as this V10.

Its more than I'd personally like however depending on the driving and what oil you are using its not bad. You could try changing the PCV valve, it may or may not help. I have witnessed several times that how a vehicle is used can have a large effect on oil consumption.

 

It has seen gentle street use at this point and a small amount of towing. I am running M1 10W30 which is a little thicker than the 5W20 stuff they recommend that I would not put in an engine south of the Canadian Border. M1 tends to boil off some in the first 1000 miles but it seems like it is not leveling off at all. I guess I should not expect to much from a 10 year old engine with almost 100,000 miles on it. My Ranger has spoiled me but it is 1/3 the displacement and has 6 fewer pistons to leak oil.

I have used M1 several times and have noticed a decent amount of consumption with it even compared to full synthetics.

My dad was recently concerned with oil consumption on his truck so I changed the PCV. Even with the new PCV consumption stayed the same. He drives 5 miles one way to work and back every day so his truck gets up to temp and gets shut off. He also does a lot of other shorter trips. Driving like that consumes I'd say a quart every 1500 like yours. The thing is when he goes on vacation he puts 1k miles towing on both highway and backroads and there is no noticable change in level. He has been using Pennz Platinum, M1 truck/SUV or Valv Synpower. All with similar consumption. My 6.8l uses maybe half a quart in 3k miles.

You could try a synthetic blend oil and see if you notice any difference.

 

I agree with dkf. More than many, but definitely a long ways away from being a concern. More of an annoyance. When you stop to think about it, one quart after 1500 miles is like, well, 1/100 of a drop per engine revolution...

 

Run some AutoRx though it. That stuff works wonders. I've used it on both of my Audis that had heavy sludging and my oil consumption all but stopped on those cars.

 

Well I need to get some more miles on it and see how it does on long trips. Work is about a 25 mile one way trip so it gets hot for a while and it is about half stop and go and half highway driving. It looks like it will be ok on long trips but I need to keep an eye on it.

I've only been through one oil change since I bought my truck this spring. But, it only used about a half of a quart in 3000 miles. That's with 125k on the odometer.

 

My 99' used about the same amount but it was never a problem. I found that on long trips it used almost nothing but that would increase in shorter trips.

 

My 2000 V10 F350 with 115,000 miles on it does not use any measurable amount of oil at all. I bought the truck new (22 miles on it) and have changed the oil every 3000 miles. Castrol 5W30. 5W30 is what is recommended in my 2000 owners manual. I do some towing, some highway, some off road and some heavy traffic. I think that sometimes when you purchase a used truck, the treatment by the previous owner has the most to do with oil consumption. Some people just do not take care of their vehicles knowing that they are not going to keep them. I also think that picking any good brand of oil that meets Ford's specifications and sticking to that same brand over the long term will do the most to prevent/reduce oil consumption.

 

Does it smoke when you start it up? I would put some sea foam in the oil and let it run. It just might be that your oil returns are gunked up.

 

1 Qt per 1500 miles seems like more than a slight annoyance to me. I would definitely see if the engine has a sludge or PCV problem that may be a correctable situation. I purchased my truck used and now has 72k on it but have no noticeable oil consumption. I have since I purchased it only used the Motorcraft Syntec 5w-20 and change it every 3k.

 

Be happy that not bad.

We junked our 01 F250 crewcab V10 with only 170k miles. Dealer bought for $5000 and try sell at auction. None of them bought so they junked.

It would burn 5 quarts under 500 miles with HEAVY foot.

Baby on gas pedal no floor it burn 1-2 qt every 1000 miles.

Pvc valve doesn't help on our. But our V10 was WORN OUT from tow 15k 5 wheel camper.

 

Well I am going to just monitor it for now. Maybe the synthetic oil I put in there will clean some crap out. I suspect it is valve stem seals. I had an Eclipse that burned oil like mad and I bought it new and always ran synthetic in it. It got real carboned up from burning oil that came from bad valve guide seals. I did a head job on it and it runs like new and does not burn oil.

If it ain't broke, don't fix it - in other words, NO SEAFOAM!

I was thinking about this the other day, and I have a few questions and/or observations:

1) When do you check your oil? Do it when the engine is stone-cold, in the mornings, before you start it. Check it every few days that way and see if the oil is really dropping.

2) When you check it, how high is it on the dipstick? The 2-valve takes 6 quarts of oil. You don't fill it to the "full" line, the owner's manual says to just put 6 quarts in it and if it's between "low" and "full" lines on the dipstick, LEAVE IT.

3) When do you add oil? At the oil change only, or inbetween to keep it to the full mark, and if so, WHEN are you checking it, engine recently started, or after sitting overnight?

I am beginning to wonder if it's a combination of not checking the oil at the same time all the time, and overfilling to the point where the crankshaft is whipping the oil around.

I know for a fact that I used to get that blue puff of smoke on startup after a quick startup/shutdown sequence, and then restart the next morning. When I stopped filling the oil to the "full" mark on the dipstick, that stopped completely. So, there was oil getting somewhere on a startup that it shouldn't have.

Something to think about.
