Replying to: shipo (Sep 18, 2007 11:00 am) "I just worked a 07 335 Biturbo yesterday USING ASTM lab tests on the used oil and M1 0w40 went from VOA flash of 430+F to 280 F in 1150 miles, oil sheared to 12.1 cSt and fuel was at 1.99% by IR." Now granted, this is data from only one forum and one expert's opinion, but it is something to consider. Combine the fuel dilution with the high oil temperatures seen on the N54 and I'm thinking that these engines may not last much over 100K -if that long- especially if the oil changes only take place at 15K intervals. And, while neither manufacturer requires the use of synthetic oil, Mazda calls for 5K changes on the DISI and Subaru has just announced that a 3.7K OCI is mandatory for all of their turbo motors.

Replying to: roadburner (Sep 18, 2007 6:15 pm) Regarding the UOA from the 335i, hmmm, don't sound too good. That said, I find myself wondering what kind of driving regimen that car was exposed to. Manhattan traffic? Road Atlanta on weekends and garaged during the week? Local errands and no chance to get fully warmed up? I kind of think something like the above was going on to cause the owner to pay for a UOA after only 1,150 miles. Another thought, was the 335i tested one of the early models sans oil cooler? I may have time in the next few days to nose around over there and have a look-see. Thanks for the "heads-up". Best Regards, Shipo |

Replying to: nyccarguy (Sep 18, 2007 8:20 pm) Very interesting: "She drove the 528xi and commented on how rough the ride was and ..... ordered a 328xi." I traded in an '06 330Xi for a 535Xi as I did not like the harshness in the 330Xi's ride. To me, the 535Xi has a noticeably smoother ride. Thanks Bruce

So I am smitten with the 550i and if I go with it over the 535 then I will have to go with a winter tire and wheel package. I did have very good success with my 330i sport in the white stuff with good winter tires. Do you know if the clearance with the aero package is similar to the 01 3 series sport I had in 01? I am a bit concerned that if it was too low than I wouldn't be able to get through a few inches of snow. (if you don't know, then no one would:). Do you think the 550 would handle the bad weather in a similar way as the 330i did? (It was like a little tank). I am still trying to decide between the 550, 535i and 535xi. I found that the 550 felt heavier but in a good way, like it was a more substantial car. The 535i was light and more toss able but it didn't feel as "buttoned up" if that makes sense. It felt very much like my old 3. The 550 felt like a more civilized M car to me and I really liked the engine note. And the aero kit that gives it a special flair. The "sensible" choice would be the xi. No tire change needed and very good handling in the wet but to me it drove very similar to my wife's X5. Not that that's bad at all but it felt a bit "heavy". I also may want the goodies that are only available on the non xi cars: sport auto trans (I hear it's great, any feedback?), ARS, and sport suspension. Oh, and do you know anything about an "anthracite head liner". I see it referenced in some bimmer sites but I can't find it in the brochure. Thanks!
