Am I screwed? Blackstone Labs report...

Hey guys. I am currently in the process of doing a 133k mile overhaul on my 2004 325xi. (control arms, ball joints, axles, all fluids, ps reservoir, steering guibo, urethane bushing, springs, struts, VCF, Oil pan gasket, plugs, filters, new key, engine mounts, misc hoses).

I decided to try out blackstone labs so I sent them a sample of my oil. I was checking it mainly for any coolant since the car did overheat slightly when the water pump failed. However, the oil analysis report I received back from them looks completely demoralizing. Looks like engine wear at twice the national average. What do you guys think of it? Should I be concerned? Any tips? I have had this car since approximately 40k miles. I have done oil changes every 5-7500 miles with OEM specified BMW oil. Is is the beginning of the end for the engine? Did I just dump 3k for nothing???

How are you driving the car? Conservatively? Flooring it everywhere? How about startups- are you letting it idle long? Are your trips very short?

Multiple things can factor into bearing wear. Would I be concerned- Yes I would, however I would send another sample on the next oil change and see.

Just drive it and keep changing the oil. If it blows, a decent used engine is going to be far more economical than a full rebuild. Occasionally, ignorance is bliss!

Honestly, I do not think this car saw passed 80mph since I have owned it. Now that you mentioned it, my trips have been very short during the last year. I tend to let it warm up for around 10 mins. I will definitely send them another sample in the next 3500 miles.

When the engine oil is cold, it cannot lubricate properly. On a totally warm engine, the oil is around 210F, which is why Blackstone gives you the oil viscosity at that point.

The oil doesn't reach this temperature until well after the coolant has reached it, so don't rely on the temperature gauge to tell you when your engine is warm enough to start redlining your shifts. It takes about 30 minutes for the oil to warm completely.

Change your driving habits, baby the car until you've been in it for 30 minutes, then send your oil to Blackstone at the next change. I'm sure you'll see a difference.

Money is this engine is running too cool due to a soft thermostat.

Suggest you check the 3rd link below in my signature on how to properly determine if the engine is running warm enough.

As mentioned, oil takes longer to come up to temperature, usually about 3 times longer on these cars with the big oil sump and lack of a oil cooler (most water cooled oil coolers are really oil heaters at the end of the day anyway!).

Did the oil you sent them have 3k miles on it? Or was it your normal oil change interval of about 6K?

I'm no expert on oil analysis, but if it really had 3k miles on it, I'd be a little concerned. A significant portion of engine wear occurs in the first few seconds. If you start your car often, but don't put on many miles, that can cause high readings. Of course, I could be wrong . . .

Yeah this oil had around 3k miles on it. I had to do the oil pan gasket so I dropped it earlier than usual.

Damn, you're good. Definitely check your engine temp per jfoj's link to make sure the thermostat is working properly.

A ten minute warm up is way too long. 2 or 3 minutes and then drive it conservative until @ operating temperature. Other than that I would follow everyone else's advice.

A 10 minute warm-up is a terrible thing for any car. Give it a few seconds to circulate the oil. On a cold day, 30 seconds, perhaps a minute if you're well below freezing.

Sorry, I don't want to start a warm-up debate but prolonged idling is one of the worst things you can do to your car (cold or warm). To quote Bob Sikorsky, author of "Drive it Forever": "...prolonged idling is considered one of the most severe operating conditions". Reducing the amount of idling will: "reduce deposit buildup and wear directly attributable to prolonged idling", "Less engine idle time = fewer engine deposits = less engine wear. This rule becomes even more important when the engine is cold".

Honestly, the manual tells you to start it and drive off. I usually start up, and leave my house, keeping it under 3k RPMs until the engine is warm.

Yep, actually takes longer for the engine to warm up idling than driving. And in an idle situation, the oil even takes longer to warm up than if you drive the car.

Start the engine, let is run long enough for the idle to drop down, not more than about a minute and hit the road.

Most cars get to about 140F coolant temp in the first mile, but the oil 2-3 times longer than the coolant temps. Withing about 10 minutes the engine should be up to full operation temperature, but it takes 20-30 minutes for the engine oil to get up to temp depending on the driving conditions and outside temps/the starting oil temperature.

Yeah I usually let it warm up between 5-10 mins when it is below 50 degree outside. This seems to solve this issue that I have when it is cold with my tranny. (When I put it in Drive and the car is really cold and has sat for a few days, it just revs and does not go anywhere. Once it is warm, it operates perfectly)

I agree and it's also what I do. Start, back up after 5-10 seconds, then take it easy (you don't have to baby it, either) until the motor is at operating temperature.

10-minute warm-ups and entirely short trips is more than likely the cause for that abnormal engine wear.

One way to try to overcome the transmission not engaging is to manually put the car in 1st gear, stab the throttle quickly to boost the fluid volume and pressure, usually you can get the clutch pack to engage, then drive and manually shift, letting off the throttle slightly to manage any slippage.

Usually after 1-2 blocks the trans should shift find on its own unless the temps are below freezing, then you may need to baby it a bit more.

I like to pull out of the garage while the rpm's are dropping from the start crank.

OE oil from BMW is garbage and shouldn't be used in an M54 or M56.

Is 3000 miles typical for you? There are studies that show changing an oil too early could actually be detrimental.

For reference, this is my dad's 535 with 17k miles on the OE oil. I know, very different engine, though I would argue that it's harder on oil than any M5x engine.


Also, you most likely have an M54, not M56. No XI came with an M56

Can you provide a link(s) to "studies that show changing an oil too early could actually be detrimental"?
