Just went on a 2,000 mile road trip to Florida and back with a fresh PP oil change in it. Upon arrival we checked the oil and found it was around halfway down the hatch marks on the dipstick. This is the second oil change using synthetic oil on this car (2000 Lincoln town car 8 cyln with 61,000 at time of purchase this summer) So back to Florida, its down a half a quart and i tell him lets see how much more it eats at each fill up. We make it about halfway back to Indiana or another 500 miles and i recheck the level, Its now at the bottom of the cross hatches and im ready to add oil. (at around 1,500 miles) I put Penzoil yellow bottle in it as that all that was on hand. So i topped it up and we finished the ride home.

Dad made no mention of the car using any oil on its maiden voyage with pp and 4,000 mile OCI after its first long road trip this summer.

Car runs tip-top, not so much as a miss or a hesitation, no smoke and the oil remains fairly clean looking on the dipstick.

I know GM says a quart of oil every 1,000 miles is within spec, im not sure about Lincoln..

What say you ?
 
1 quart in 2000 miles....Meh...I would go another 2 oil changes with PP before I made a decision. Sometimes engines will use oil when converted to synthetic but the consumption usually subsides. Do give it a look over underneath for any leaks.

5-20PP & 73-80mph interstate almost the entire way.

And it ate around a quart in 1,500 miles doing this.
 
I've experienced this on my Mazda when using PP, it was down a qt. after 2000 miles and rather dark. The second oil change with PP there was no drop in 4000 miles. No other oil I've used in this car did this.
 
5w30 was originally spec'd for that car. Only with the introduction of the PI heads did 5W-20 become to norm, and even then they increased the sump capacity for MY2003.

Having owned 4 different Panthers over the years, I would suggestion one of the following:

- GC 0W-30
- PP 5w30
- M1 0W-40
- PU 5W-40

And replace the PCV valve whilst you're at it. Good luck!
 
I believe 1 quart every 2,000 miles is reasonable as long as there's no leak, strange sounds, performance drop or smoke, with topping it up if it gets close to minimum. My MB 92 W124 consumes 1 quart every 1,250 miles (2,000 kilometers) and the user's guide says max consumption is 1 quart every ~900 miles. I guess it applies to all old engines.

I would worry if it happens with my 2009 CV, but for your 2000 Lincoln, I would use it longer then check the engine if consumption increases, specially valve seals, at the local dealer. Shouldn't be a problem for you, probably, since you're in the States.
 
PP 5W30 is what I would use if it was my car... Stay with it for 2 OCI's and hopefully the consumption tapers off. If not, then use plain jane PYB...

I'm sorry, "old engines" and valve seals? The OP said this Lincoln only has 61,000 miles on the clock, which is nothing for a Ford Mod motor. If this was an engine built before 1996, I can also understand issues with valve seals, but this is barely a problem with a '96+ 4.6L. My '01 Grand Marquis will be hitting 200,000 miles soon and barely consumed ¼ of a quart between 7,500 mile drain intervals on 5W-40 A3/B4.

It's been my experience that 2001-2002 MY's do consume 5W-20 ILSAC rated oils. The same applies to 2003+, but the slump capacity has been increased and it's not nearly as dramatic as previous models. Considering 5w30 was originally spec'd for the OP's engine, that is, at a bare minimum, what I would use. I personally favor A3/B4 spec 0W/5W-40 in these engines.
 
Remember, too, that it's not unusual to see slightly increased consumption after a change in oil brands and from conventional to synthetic. I agree with Boss302fan: see where you are at the end of this OCI. My ex-wife's Marauder (not the one in my sig) used a bit when we switched from MC 5W-20 to PP 5w30 some years ago (it was bought used). It now has 170,000 miles and burns less than it did when we bought it with 87,000.
 
I wouldn't worry too much like RF Overlord has said; stick with the PP for another OCI and then go from there. My vote would to be check the PCV valve as well.
I am quite surprised that your dad's Lincoln is consuming oil like that albeit a small amount. I've ran PP 5W20 for multiple 8-9K OCI's in my 2005 CV with 120K on the clock and never had any consumption issues; it comes out almost as clean as it did going in. The other car is a 1998 Grand Marquis that has 270K+ on it and it used to consume Pennzoil of any flavor like your dad's Lincoln but as soon as I put in Valvoline Maxlife, the consumption went down to next to nothing over a 4-5K run. Even though I've never been a Valvoline man, I will continue to use in in that car so perhaps it could work for yours if you cannot find any external leak and the PCV is in good working order.

Im almost 38 yrs old and have owned 16-17 auto's and ive never had one that would do this (oil clean going in and looked clean getting dumped out). My 07 Accord doesnt use a drop and ive never had to top up even a pinch on that car.. and its the only one out of everthing i have owned thats been like that ! But after 5,000 miles its not Black but its very, very dark brown. 6,500 is my personal limit before i have to dump.
 
i would not worry at all 73-80 all the way and the valve guides are being lubed well.... Every engine made uses oil some very very little but if they stopped using oil completely they would seize up..
 
Non-pi (prior to 2001 in panthers) 4.6s sometimes use a little oil. Just keep er topped off. 4.6 runs forever

Actually, I was referring to the basic design of the engine as it goes back to at least 98 or maybe even older. Those symptoms AFAIK are due to, among others, worn valve seals as I experienced with my W124. Engines of older generations may have problems in this department. Panther platforms used the same engine as standard so I compared it to CV's. On the other hand, neglecting engine oil could wear the valve seals of any engine at relatively lower mileage. I believe the engine oil maintenance history is unknown for this used car. It could have been stored (stalled) for a very long time which causes the seals to dry and crack. I've seen some MB W124's and W126's have this problem and their engines are considered of the best in reliability.

Either way, your reputation precedes you and your the expert. I could be wrong in every thing I said, and that is why I always suggest checking.

I'm also interested in what else you would suspect if the PCV valve was not the culprit. And do you consider the subject consumption over the safe limit? I could use such info, much obliged, for the future on my CV.
 
Don't believe the spew that seals dry and crack on any 4.6 newer than '96, doesn't happen even if it's rarely driven...

Cracked valve stem seals in a OHC engine will result in consumption in the range of 200-400 mi qt...
