Hi Leutz, have 2 questions for the motor specialists among you: 1.What do you recommend for oil with a new engine: BB with aluminium heads, compaction 9,6:1 ? I’ve always poured in normal 10 W 40 with my 396er and wanted to ask now if I should treat the new from the beginning something better 2. How do I best preserve an engine ? Thanks already greeting Stephan
