Default 2003 bmw330ci with 27,000 miles no break-in service

This car is being offered to me by the original owner who faithfully followed the Free Schedule Mike talks about in his wonderful piece. Therefore, no break-in service and a long interval between oil changes, brake fluid, valve adjustment. But only 27,000 miles.

Any suggestions about the dangers of buying this baby besides paying too much?

If "this car" is an M3, then it should have had the break-in service, though I know it's not always the case. If not, the best advice is ALWAYS to get a PPI (Pre-Purchase Inspection) done. It's money well spent.

I have seen that the engine and drive-line oils in new modern BMWs are literally full of metal at 1,200 miles – as has always been the case with any new car. For this reason, I recommend a 1,200-mile break-in service.

Engine

Oil and Filter Intervals

BMW recommends their Castrol 5W-30 synthetic motor oil in all BMWs except contemporary M cars, for which they recommend their Castrol 10W-60 synthetic motor oil. The factory oil change interval is controlled electronically, but is presently about every 15,000 miles. If you are running BMW’s oil, I recommend an oil and filter change interval between 5,000 and 7,500 miles.
I have a quick question on this. My engine was rebuilt in February (due to a cracked block)...they used a new block, pistons, & seals/gaskets and swapped over everything else from the original motor. I've been following the break-in instructions just to be safe even though the SA said it wasn't necessary...keeping it under 5500rpm, no extended high speed runs, varying engine speeds, etc. I've put about 1,250 miles on the car since the rebuild. Should I have the oil/filter changed now or am I okay till the 5k-7500 mile mark (when I would have normally changed it as the in-between interval)? My transmission was also replaced in April (factory rebuilt, I believe) under warranty...do I need to have the trans fluid changed at any sort of break-in interval or just at the 30k mark?

Thanks in advance for your help!

My advice, fluid changes are cheap insurance. The idea is to flush any loose metal shavings or debris that is inherent in the machining/manufacturing of an engine/transmission. Your SA is lazy, misinformed or doesn't want to eat the cost of the service, though I can't imagine why it wouldn't be covered if it was all replaced under warranty. Always follow the break-in procedure for new or replacement parts, always.

I have no personal experience with supercharged E36 M3's. I would suggest you contact the blowers manufacturer and ask them for advice. Failing that, Mobile 1 or Redline synthetics are a good place to start. Change it often.

- Dealerships have a stake in recommending frequent service. It makes them money.

Also "magically", most of the engine line-up changed. A lot of the advancements that characterized those engines had to do with metallurgy and engine management. Hmm. Maybe that played into things a little bit.

Yes, please do.

But as long as we're advocating skepticism -- which honestly seems a bit hypocritical in an article that paints a very limited picture of the situation and then says "draw your own conclusions" -- let's bear in mind the following:

- BMW has some of the best powertrain engineers in the world.
- BMW's brand is all about sustainability and reputation, which means they depend strongly on resale values and long-term customer satisfaction.

Think about that when you evaluate whether BMW would gamble on screwing you over just to save a few bucks right now.

And that makes it credible? What is your basis?

Aha, here's the disclaimer. But if this is the case, of what use is the opinion? What this really says is, "all of this is my gut feeling and there's really no data to back it up." That's fine, but it shouldn't be presented with any attempt to sound credible (i.e. the first few paragraphs).

Translation: O NOES I SEE METAL, CHANGE TEH OILS

I know what he's talking about. Oil used at break-in usually comes out looking glittery because of metal bits that are just big enough to cause light to glint off them. Well, if you think those metal bits are harmful and BMW has never seen them in their testing, you probably shouldn't trust them enough to buy their cars.

Under racing or track conditions I’d use a short interval; same for carbureted engines which tend to get some fuel into the oil. I would run the same intervals with very high end synthetics such as Amsoil and Lubrication Engineers Monolec Ultra.
Wait a sec. So you wouldn't run factory oil change intervals with an oil designed by BMW and Castrol specifically to run that long in BMW engines... but you would run MORE than that with a product from a company that prides itself on never paying for third-party certifications?

I like Red Line too, but cripes...

Half of Mobil 1's products don't even carry the ACEA certifications that qualify them to be considered for BMW's testing.

We don't know much about the BMW Castrol product? How much do you know about "all other commercially available synthetic oils?"

The BMW Castrol product was specifically designed and engineered to BMW's specs fro BMW engines running BMW OCIs. Can't say that for the other oils.

While you're thumbing your nose at BMW's recommendations and putting forth your own, you might want to say something about what cars need synthetics and what cars don't. Just a thought.

So?

LOL, no. Not even slightly. Some are known to be predominantly group III (e.g. Pennzoil Platinum), but to say "all others" are group III is ludicrous. Motul, Fuchs, Elf, Lubro Moly, etc. all make group IV/V synthetics.

Not all Castrol Syntec is group III. The 0w-30 and 5w-50 definitely are not.

Not all group III base stocks come from slack wax, either.

I was about to say "wow, finally some good info" but I realized that not even this is true. Some of the lighter viscosity grades (e.g. 5w-20) have to have some synthetic component just to keep from evaporating too quickly. Oddly enough, this makes them thicker in the hottest parts of an engine than many non-synthetic 5w-30s...

Orly? How so?

Motul and RLI are all about esters, too.

Esters don't guarantee good performance anyway. Again, it's the whole formulation that matters.

Red Line isn't even close to being in a category by itself.

Okay, NOW we have some good info.

...but why the sudden faith in BMW's recommendation? If they're too incompetent to recommend an oil, what makes you think they're competent to recommend a filter?

In other words, "there might be a problem, therefore there is a problem." Interesting logic.

Sounds like this is referring to the 4-tip platinum plugs. If it isn't, I have no idea what it means. Platinum plugs last a LOT longer than copper plugs at the expense of spark strength for a given amount of energy. That's the whole point.

K&N oiled cotton gauze filters, clean every 15,000 to 30,000 miles depending on condition, use only K&N approved cleaner and oil, and follow K&N cleaning procedures
No mention of severe service or climate as with the engine oil recommendations? Why not?

When was the last time you saw a reasonably well maintained BMW engine that had clearances that were out of spec in that interval? The only ones I've seen were barely out of spec (if at all) after 3-4 times that mileage.
