Hello all, I'm a new BMW E46 330i owner. I bought my car used at a Ford dealership and I am concerned about if they put Castrol Synthetic oil in it or not. My service indicator says i still have about 2,000 miles left. Does the oil really last for 15,000 miles on the right oil? How often should I get the oil changed in this type of car? Thanks in advance! |

Replying to: brave1heart (Oct 17, 2006 6:22 pm) When reading an oil label, the first number means that when the oil is cold, it flows like a straight weight oil of the same number when it too is cold. The second number means that when the multi grade oil is warm, it will flow like a straight weight oil of the same number when it is also warm. Said another way, 0W-40 is still thicker when cold than when it is warm, it just doesn't thin out as much as it warms as a straight weight oil or another oil that starts with the same first number but has a lower second number. Regarding fuel economy, the first number only affects the fuel economy for the first few minutes following a cold start. The real benefit of a lower first number is that since it is less thick when cold (especially when it's REAL cold), it pumps up into your engine faster during a cold start and as such, keeps engine wear to a minimum. Relative to the oils that carry the BMW label, the 5W-30 is the Castrol oil made for BMW for their non-M cars while the 10W-60 is for the Ms. As there is some question as to the true quality of the BMW/Castrol oil, it seems that the best choice for a certified BMW LL-01 oil is either Mobil 1 0W-40 or German (as in says "Made in Germany" on the label) Castrol Syntec 0W-30. As I prefer a spotless engine (on the inside at least), I lean toward Mobil 1 which seems to be unmatched at keeping the innards clean. Best Regards, Shipo

Does anybody know why air intake should be restricted at low RPM? Why VANOS are better than air intake butterfly at low RPM? Lehrer

Replying to: lehrer1 (Oct 18, 2006 10:58 am) If the intake system of an engine is too free breathing, then said engine will be gutless until the RPMs come up to speed. Why is turbulence so important? It aids in creating a uniform distribution of air and fuel within the combustion chamber. The better the air and fuel is mixed and the better said mixture is distributed around the combustion chamber, the greater the amount of power that can be derived when said mixture burns. Best Regards, Shipo
