And I can say for sure the last run was during middle of the summer where we get 100+ degree weather in SC and the car was driven very hard. Even harder than when I ran the 10W60 because we went on at least 5-6 mountain runs which the temps can see upwards of 230F. Take it for what it's worth, but this was pretty compelling to me. P.S. I don't hoon my car unless it's up to operating temp, so the 9PPM lead was going to be there regardless of what I do.

Agreed but like he said "The car is driven "very" hard !
So it's normal to see more metal and this with any kind of oil,when it was a garage queen than there was 0 metal !

My M3 is an 08.
I just bought the car 3 weeks ago at 40k miles. The last recorded oil change was at 26,444 according to car fax. I put 500 miles on it and I have good reason to believe that the oil is TWS due to it was last changed at Pembrooke BMW in Florida but I really don't know how many miles on the oil. It looks like I have to keep an eye on the lead level. The car is running on Mobile 1 0W40 now.

Universal average is 8ppm, mine was 9ppm. Not even the least concerned about that.

Your iron was 5 and went up to 9 on shorter mileage.
Its hardly a fair and balanced argument for a change in oil weight if you only present the benefits and ignore the downsides. Last edited by SenorFunkyPants; 04-18-2014 at 06:13 AM.. |

Let's make one thing clear here. I have 0 interest in convincing people to use one oil or the next, that's your choice. In that regard, I'd love to hear how I'm only showing the good but not the bad (whatever that might be), because that's certainly not my goal. I'm trying to honestly be 100% transparent with everyone.

W///, that's what I got out of your UOA report as well, drastic decrease in lead, mild decrease in copper, and you increased your iron wear to the avg. level because you beat up the motor. But SFP being an advocate against lighter oil will surely come in and rain on your parade, and surely he did.
I say keep using M1 0W40, and knowing that the oil is doing its job. |

If the last report came back with something like 20PPM iron, then I'd clearly point that out. Heck if you read their summary, they even mention word for word what we are talking about "hey we noticed increase in iron. Did you drive car hard? don't worry though, still about average. Nice report"

Actually I'm an advocate against a small vocal minority promoting a change of oil type away from the OEM recommendation with absolutely no long term data that shows any advantage....and I'm especially against glossing over UOAs that show a rise in iron - if you can't drive hard with Mobil 1 0W40 on board without a rise in iron then that IS a reason to be concerned.
The topic is rapidly become like the tight bearing clearance fiasco - where the idea (M1 0W40 is better) becomes fact solely by constant repetition. Last edited by SenorFunkyPants; 04-19-2014 at 05:32 AM.. |

Would you concede that the lead and copper readings have gone down with the 0W40 compared to the 10W60? I don't know about what you consider long term but the reports have shown less wear on the rod bearings with the 0W40. There is no denying that. As for iron, there has been high traces with the 10W60 as well. I think you like to take in what you want and ignore the actual test results.

You are against UOA's showing rise in iron? There are so many engines on your beloved TWS with higher iron than mine! Just quickly scroll through the thread and you'll see iron levels in the double digits, which mine isn't The last report showed exactly the opposite of what you are saying. Oil was used hard (in hot weather), yet lead dropped, and everything was right where it should be or better.

Universal averages don't enter into it. Other cars and their UOAs don't enter into it. Its about trends in your engine. You changed your oil type and lead went down but your iron and aluminium went up. And yes I know the Aluminium and Iron are still within the UAs but then so was the lead with TWS. Jeez its not rocket science. Last edited by SenorFunkyPants; 04-20-2014 at 05:03 AM.. |

So you're content with the known trend of increasing lead, copper, and iron levels in high mileage cars that use tws?

For myself I'm not bothered, I'll have a BMW extended warranty for as long as I keep my car, if the engine let go that would be fine with me, I'll get a new one.

Isn't there already a thread or two (or three or ten) devoted to the merits of TWS vs. M1? Maybe you guys can keep this very useful oil analysis thread focused on oil reports and analysis instead of rehashing old debates?
P.S. I'm using TWS and had high aluminum and iron levels (7 and 12 respectively) on my report. Lead was low though. Still not sure if this is something to be concerned with. |
