Tracking my E46 Oil consumption issues

@zuckuss00; I would have to agree at least in my case. Before I spun a bearing in the block of my M52TUB25 motor I never ever had any oil burning issues of any sort. When I upgraded my block to a M54B30 motor I instantly inherited oil consumption issues. I'm now burning about a quart every 800 miles and I change my oil religiously every 7.5k. I ordered a four pack of MOA for my engine using the link provided. Additionally, I found that when me motor is low on coolant I seem to burn more oil. Don't know the direct correlation at the moment but I will keep the forum posted.

Do you know why you spun a bearing?

How have you determined that your oil burning is definitely the oil rings?

330,000 original miles on my engine is all, nothing more, nothing less... I spoke to my mechanic and he told me that 13 years of driving and many, many miles...

Wow, best reason I could imagine!
Many miles of happy motoring. That's a history to respect.
And in the Northeast where they salt the roads. Body still sound?



I'm impressed!!!

I drive my daily year around and wash it religiously in the winters in order to keep the salt and chemical damage to a minimum...

It does seem that 3 liters seem to burn a bit more oil than the rest, but that's not always the case. I personally had an M54B30 that burned very little oil (if I let it get that far, it probably would've been 1 qt every 10k miles). A friend of mine on the other hand has a ZHP that burns what seems to be a quart every 700 miles. If I'm driving behind him, I swear I could smell my oil. He's changed just about everything else, so we suspect it's either the piston rings or valve seals in his case. My S54 doesn't seem to consume any measurable amounts (completely different engine, I know).

I suspect it might have something to do with how the motors were burned in.

Chasing the same 200 miles per quart problem. No leaks, just sooty exhaust. I have upped the viscosity to 10W40. I don't expect any change, but we will see. BG is TOP quality product, so e-bay here I come.

I have put over 1000 miles since my engine swap a few months ago. I noticed that I am also burning oil especially during high rpm applications. For the first 500 or so, I didn't drive the car like I stole it so the oil consumption wasn't even noticeabe. The last 500, I was cruising at 90-100mph (3.5-4K RPM) and when I checked the oil it was low.

I jacked up the car and the engine compartment is clean and has no evidence of any leaks.

What are the specs of the 10W40? Is it a thin or thick 40W?

I didn't chew. I already know that you are going preach LL stuff. If that was great, how come people are having consumption issues with dealership oil?

Viscosity is viscosity. 40W is 40W. Not thick or thin.

and this BG MOA additive looks exactly like this, correct??



i just want to make sure before i add any additive into the engine.

thanks!

And I just ordered some MOA. If I can get to 1000 miles a quart, I plan on selling the wagon. If it improves to 2000 mile/qt, I may keep it. I am used to a parade of GM vehicles (4, 6, and 8 cylinders) that, at their WORST, consumed a qt every 5000 miles. "If I knew THEN what I know NOW", I would not have bought a Bimmer newer than an E36.

Not a bimmer that consumes oil, but a poorly broken in car.
For some reason lots of BMW's get treated poorly during the break-in.

My car burns only a few ounces in my 7500 mile changes, and I know I am far from alone.

Too late for my 2001, isn't it?

No. Again is it a thin 40W or a thick 40W? If you don't understand just post the oil specs from the container label

First 1500 miles are critical to break-in.
Killed me to go easy on the Autobahn for the first 1300 miles!
I'm cruising at 100 and guys are whizzing by me.

You may just be the dunbest person posting here yet. A 40W oil can vary in viscosity from nearly a 30W to almost a 50W and be called a 40W. If you don't understand tribology, best you don't post on an oil thread!

And YOU may be the most overbearing person here. Oh, you can't spell either.

I ran your personality profile and it comes up you believe more in astrology than science. We have no need for that!
