I started with 5 days and Blackstone said I should run it longer

as i stated my lack of experience on oil analysis is the reason for starting the thread

Only way to get some degree of good info is the oil analysis. My recommendations are based on never getting oil analysis results that said to change it sooner.

As far as Castrol TWS...it is the safest bet. Why would BMW put a crappy oil in their $25k engine? There are alternatives that may be slightly better or worse. IMO, if you change the oil often...it doesn't matter.

What do you run in e46?

Go do some research, and then come back at me when you can tell me what specific testing sequence was performed on that Castrol 10W60.

All I know is that 1060 is what BMW M engines are recommended, and right now BMW recommends Castrol. And then when I read the bottle is says recommended for m engines. I like the 1050 as well, but your post says that TWS is not approved for M3 and it is.

Where did you find this information?

Bmw is going to recommend Shell soon.

Yes, I;m sure it wil be the Helix

Normally use TWS 10w-60. Tried Mobil 1 which was in my E46 M3 engine when it went boom. Not saying that Mobil 1 is the cause...not sure yet. Only facts so far are:

1. Connecting rod # 3 is on my desk at work.
2. There is a hole in my block.
3. VAC oversized coated bearings had 16k miles, mostly track.
4. Bearing #3 had spun 16k miles ago.

Ouch.

Interesting. E46M3 had rod bearing issues also, resulting in a recall. Some shops like Bimmerworld recommend replacing the bearings again as preventative maintenance.

Yes and 1060 only started after the bearing recall of the e46.

The S54 continues to have rod bearing issues, albeit not as severe as the S65, but once removed, there is substantial wear.

This vehicle is tracked:

wow!!!! whats a motor cost now for the e46?

[bigjae1976]

A used one with all accessories will vary from $3k-$4k. I've found a used engine. Plan to swap in new bearings, refresh the VANOS and do a valve alignment...and go. I might reuse the head or just part it out. Thinking if I wanted a spare engine, might be easier to just get another used one.

If I part out the head, I should have a fresh engine for less than $4k.

much worse after only two or three years, hence the manuf. recall campaign.

the head of turner motorsports team said he uses castrol 10 60 in their four e92m race cars. a year later i asked him the exact same question and he said he uses the same oil in the z4 gt car and the two e92m cars. guess it's good enough for turner.

[pbonsalb]

Probably the best for a race car that is not daily driven and subjected to frequent cold starts. What is best for a race car is not always the best for a street car.

Just do a motor flush with your next oil change, and reset your analyzer. Once the analyzer gets down below 7-9K miles left, change the oil. The miles, are not actual at all, just an estimation.

I've found that yes, it does measure conductivity (search for Condition Based Service Monitoring, see here too) but Killerfish2012 doesn't understand how it works. If he wants to really rely on the "analyzer", he should be able to change the oil and the "analyzer" should pick up on that and tell him he's got an increased amount of time before his next oil change now, right?! Why do you have to reset the dang thing if it's telling you how much life is left? Doesn't it know there's new oil in it? Oh, it doesn't work like that?

It uses fuel consumption (rather than mileage) to count down a timer and tell you when you're due for an oil change. Yes, it does measure the electrical conductivity of the oil, but this isn't just lead. Did you know that copper, aluminum, calcium and zinc all have higher conductivity than iron? And not to mention there's an order of magnitude more of those in the oil than iron, but somehow this magic analyzer measures just the 10-30ppm of iron (or lead, or whatever you think) that's in the oil and ignores the 2000-3000ppm of additives that have higher conductivity.

So when most assume it to be useless, they are more or less right. But I'll let Killerfish2012 go ahead and think his magic sensor tells him when his oil is full of iron and ready to be changed.

Edmunds.com actually did a study on vehicle oil analyzers, using the Pontiac G8. They found through oil analysis that the oil analyzer truly was reliable till it actually said the oil was no good, so I'm not sure what you're trying to get at here? Should I trust reputable automotive media, with data, or internet guy?

Sir, since you don't need yours, then simply cut the wire leading to the sensor. Simple as that.

I'd be more than happy to, if only I could still measure oil LEVEL without it

Is this what you call a study?
Edmunds sends in for a single Blackstone analysis

If you think the sensor is so accurate, why are you changing your oil when there's still 7-9k miles left of use?
