Hi everyone,
I have a 2009 BMW 318d with 2 liter N47 engine, with quite some mileage: 175k. Stock one, DPF is in place, so LL-04 and Euro-5. Last 50k I use Castrol Edge titanium FST 5w-40 due to it high viscosity. However I heard some stories that Castrol oils make the inner of engines dirty. Now I wonder if I should use
1. continue to use this Castrol Edge titanium FST 5w-40
2. Use M1 ESP 5w-30 because of Mo etc, despite the fact it's thinner
3. Use M1 ESP 0w-40 as clean oil.
What would you suggest, please?
