Default How much oil does a ST N54 burn? - 07-11-2017, 11:20 AM

Anyone else out there with ST N54 please comment.
How much oil do you burn?
Do you have a catch can?
Does a catch can cause more oil consumption?

Oil weight would be a good one to add. I like 10w40

I personally don't have oil consumption issues with an OCC too.
Occ installed shouldn't have any effect on oil consumption.

I use motul 5w40.
And I've consumed a quart in 1,500-1,800 miles or so. I do drive my car hard.
I do have a OCC as well.
What's odd is last week my oil reading said minimum so I added about a quart. Level indicator said almost full it was a little above half.

Drove it for about 250-300 more miles... While driving it said half still.
The moment I stopped and turned the car off it said minimum again. No visible leaks or smoke.

Our sensors are complete garbage. I've had mine tell me it was low, add to full, then drive 5 miles and tell me it's low and to add again.

Yeah.... it's pissing me the F off man. My M5 sensor seems to be pretty damn accurate. But my 335 one has never been accurate.

I'm surprised no ones done a oil dipstick modification.

Haha!

Yes, I've noticed that if my car is parked on a SLIGHT decline, it'll tell me I need oil, the sky is falling, etc. I have learned to not be hasty, as the next time it does whatever it is supposed to do and the car hasn't been on a slight decline, it's fine.

Ugh this car is trying to give me a heart attack I swear lol.
I guess consuming 1 to 1 and a half of a quart of HARD driving bacially track days one after another is normal.

Car pulls and drive fine. No smoke at idle at a light etc

I guess from blowing the first motor due to leaky injector I have PTSD with my car.

Hard to believe.

Do you go into full boost every single chance you get? I do.
I drive my car at 120+ every single day. So I'm guessing that also has to do with oil consumption LOL

Our 535i 2010 with 34K miles burns under a half a quart every 5K miles. Our 335i 2007 with 88K miles burns a quart every 1500 miles or so. It has both the BMS and RB OCC's on it. Our 2008 335i with 54K burns a quart every 5K miles.

Interesting. Your 88k miles car burns about as much as mine does. Basically the same. So I guess it's rather normal?

LOL! I use Motul 5w40 right now. Burns 1 quart every 1500 or so. Next oil change I could try the Rotella T6 and see how it goes.

Personally, I think a quart every 1500 miles is excessive. According to BMW it's in the range. I just switched to 5-40W from 0-40W. We'll see if that helps.

Right it may be excessive that's what I thought.
But considering the car is single turbo and driven very hard?
I use to burn a quart to a quart and a half at a track day. And that's totally normal.

I already use 5w40 and still burns a lot. Maybe Rotella T6 wont as much.

The 2007 335i with 88K that burns a quart every 1500 miles has DCI's, FMIC, ******* ********* and MHD. I think the boost is around 16 psi or so. Nothing crazy.

The 535i (34K)which pretty much doesn't burn any oil just has DCI and JB4 set to map 5. Don't know if it's the mileage or add on's but that's a big swing between the same engine.

Yeah that is odd. I honestly think it just has to do with the health of the motor.
I'm on my second engine right now. And I think the used one I got cyl4 might be bad... so that'd be my oil issue. But... then again I'm not sure. Considering the car doesn't smoke at idle at all. And no smoke comes out of oil filler cap after a hard drive either. Only vapors.

I remember my supercharged E46 wouldn't consume any oil what so ever. So yeah I don't know lol.

My M5 consumes about 3 quarts every 5-6k miles though. Which is totally normal for that engine.

I've heard burning oil is a sign that the car had an improper break in procedure, thus making the Piston rings not seal properly to the cylinder walls and this causes excessive oil consumption.

Well that's what I mean, engine health. I got this motor used at 84k miles. So who knows what it went through before I got it. Good thing I got a warranty on it.

Woah that's a pretty high mileage motor, I'm guessing no lower milage ones available?

Wow, where'd you buy it from to get warranty and how does that work?

high mileage? LOL

Anything under 100k is low mileage with that motor.
Or maybe I'm just use to driving my cars a crap ton?

I drove over 35-40k miles a year so I don't know.
Put it this way. I had bought a maserati GT with 15k miles and drove it to 99k miles within 2 years as my daily.
That'll give you an idea lol.

Any reputable junkyard will give you a 90 day warranty with anything you buy in general. Luckily this place I've been dealing with for over 15+ years. They'll honor it as they have with many other parts in the past.

I don't really know.
1. I'm Canadian so in KM anything over ~62,000 miles is over 100,000km which I consider high.
2. I dont really buy used cars because I don't know what happened to it before hand.
3.Never bought anything from a junk yard before So I wouldn't know, again I dont like buying used stuff. Personally I just buy everything brand new because I like the idea I get Factory warranty and it's in excellent condition and I'm the first one to use it.

I've come to the conclusion that 1 quart in 1,500 miles i not normal at all.

My used motor I got is bad for sure 100%. Consumed a quart and a half of oil in 1,500 miles. Then another quart in 4 days.

Pulled plugs found cyl4 covered in oil. Saw wet oil all inside of cyl4. Motor is bad.

Onto my 3rd N54.... These engines are real "strong"

Most broad sentences ever. What mods do you have? how hard do you drive? what plugs do you use? what's the condition of your turbos? what tuning do you have? etc etc etc can't be like

"cars good. Good motor kthx"
