Mein Auto: Alpina B7 e66
most of bmw E65 had this issue oil burning becouse a lot of people using full synthetic for long time 20,000km-25,000km and thats whats make the valve seal bean hard. so for me i buy Titan oil very cheap and change it every 5000km-7000km butter then buying full synthetic oil.

full synthetic is very soft oil and most of the previous e38 e39 issues with the vanos was from this oil.
