The best engine oil?

[mattadav]

Guys, which engine oil do you think would be the best to be used on a M54 engine?

1. Mobil 1 0W-40
2. Motul 300V POWER 5W-40
3. Motul 300V POWER RACING 5W-30
4. Motul Specific LL-01 0W-30
5. Shell Helix Ultra 5W-40
6. Castrol EDGE 0W-30


any comment??

I would go with a Hellix Ultra 5w/40-my first pick(very, very good oil) or Motul 5w/40.For sure I would not use any oil with "0" weight in hot. humid climate of Hong Kong.
Just my opinion as a chemist and ex-petroleum industry engeener.

I am using Helix Ultra at the moment, i have used Mobil 1 before,
and Helix Ultra is working better on my car, thanks for your comment,
100% agree Helix Ultra is good, but I think I am going to try Motul 300V 5W40 this time,
at least for once

do you think Motul 300V 5W30 will be better than 5W40 to use in a 323ci with only 30000 Km on the meter,
under the climate conditions in HK with the heavy traffic problem? used:

Personally I am not in favour of using any 5W/30 oils in BMW engines, because of low viscosity index at 40 and 100*C(too thin) and mostly these oils do not meet BMW specification >3.5 cp for high temperature high shear strenght, better stick to 5W/40 oils (you are not in Minesota or Canada) Ha, Ha .Ha....
BTW 5w/30 oils are good for some 7 series and 3 series equipped in "valvetronic" valve system.

One more thing, Motul 300V series is not realy approved by BMW, it is mostly recommended by Japanese car manufacturer like Honda or Subaru.
If you wany to use Motul, use Motul 8100 X-CESS series, which is approved by BMW.
