Hi,
I was wondering which option is better:
Change Engine oil with PennzOil Syntech with 7500 Miles by 104$
OR
Change oil at dealer with 15000 miles by 160$ ?
Which one do you prefer best?

BMW Long-life rating LL-01 Approved Synthetic Oils for the US Market:


Castrol Syntec European Formula SAE 0W-30

Mobil 1 SAE 0W-40

Pennzoil Platinum European Formula Ultra SAE 5W-30

Valvoline SynPower SAE 5W-30

 

Use 0-XX weight oil if possible, it provides the best protection at start-up which is when most engine wear occurs.
