1. What is the best oil to use with 2003 E46 320d (6Sp), synthetic oil or normal diesel turbo oil and what brand? I see on the oil cap they recommend Castrol Oil?
2. Can I use Prolong or PS23, or is it not recommended? I used it on my 2.8 V6 Audi and it was good for the engine.
3. What diesel is the best?
4. I went to the Eastern Cape and towed a Camp Master Town and Country trailer and drove at 125km/h with cruise control. I got just below 14km/l, is this good enough, or should I get more?
