Does every 4.4, 4.6 and 4.8
 

has the blue smoke issue?

Do all these models eventually develop the blue smoke issue?

not mine,I had the 4.6is and 4.8is now.....................use Castrol oil.

i have a 4.4i with 175,000 miles and no smoke.. even if i push it hard

Which oil BMW uses

I have 4.6 with 109,000 mi. No smoke. Have always changed oil every 5000 mi. and always used oil that meets BMW specs.

Not on mine

Wow 5k? That's excessive IMO. I'm a maintenance nazi but with modern day synthetic I see no need for that unless its subjected to extreme conditions. My e39 has 230k and runs as clean and smooth as any. Oil changes are 7.5-10k.

Nope.... i have 75k miles and i love to push the beast hard ...no blue smoke

115k on the 4.4 and no smoke. My 4.8is never has smoke either. I run Mobil1 10-30 in all my rides except for the diesel.

Over 170k miles here, last 70k has been on M[1] 0-40 LL spec EuroCar formula. Even with severe tow duty (hauled a few 7,500 lb trailer/boat combos) I have never seen blue smoke. At oil change time the level is still where it was at last fill.
