3000 miles at changes,
My car does not use any noticeable amount.
Mine has 90,000 miles
Maybe 1/3 of a quart, but I can't really tell.
3800 II just don't normally leak or burn much oil.Pretty solid.

A quart for 2000 miles is not bad at all, and I wouldn't worry about it.
Mine, with 163,000 doesn't normally need any oil added between 3000 mile changes, but it'* starting to leak oil and tranny fluid...

oil
It seems most Buick 3800'* don't use any oil.
Dealership told me they are exclusively made for Buick in Buick plants.
The others at GM divisions. They use this as a selling point.

Lets just say that the 3800 is a hell bent engine( Not meaning in terms of power) and can take abuse like an old 350, and last just as long...
I have seen some that use a little oil and others that don't...
Don't get me started on the 3100... lol

I just came back from a 1800 mile trip. Car now has 135,000 miles. Burns no oil at all...not even on that trip. I use Castrol GTX 10w30. Change religiously at 3,000 mile intervals...and the engine gets no abuse.

I have a very slow oil drip but I have never had to add oil between changes, and that included when I had a nice drip going.
Although if you get 29mpg I would suck up adding the oil...27mpg (highway) is GOOD for me.

What, so buicks DO have the "better" 3800? :?
Good news for me yeah, but why the **** would GM make a special engine for a different car than the olds or Pontiac?
Just don't make much sense.
So what of the intake, any less chance of my Buick having problems with that?
I will say I have had zero problems with anything under the hood as of far, 90,000 miles.

From what i gather, the 3.8L Jr mention is an LN3, different engine in alot of respects versus the L36 or L27.
before the LN3 was the LG2 and LG3, different yet, parents had on in there old 86 PA, it used no oil between changes at all.
My old SSEis L67 at 150000miles+ used no oil, nor does my Bonneville now.
All 3.8s, 3800s were the same for each year, wether it be a Buick, Pontiac, or Oldsmobile, the 3800 in your 99 LeSabre is identical to that in say a 99 Bonneville N/A.
Engine mounts were a bit diffrent, some utilized the Dog Bone mounts in the front and so on so fourth.
Minor oil consumption is normal, the clearance between the rings and bore is extreamly minimal at best, still can allow for oil to pass through and what not.
