Hello guys, I laughed at a new engine and various attachments and conversion measures a month ago, which I am looking forward to and which should be in place in My Keke Rosberg Edition until April. It is a C20NE, is made/is: Head 6/10 planned LX90 camshaft Irmscher suction tube ducts processed and adapted to fan manifolds Fan manifolds Short translated F16, since the original has not understood so well with the differential anyway. next year to be coordinated with the chip, test bench and punch on the petrol pressure regulator, just everything that belongs to it But now my question, which oil do you take for such an engine? He gets the planned head immediately on the face, is there a 5w40 instead of 10w40 maybe better? Many have tested it and find it bad, I have to say the engine sweats a little bit at the oil pan, that gets even worse with thinner oil. fz Mechatroniker) recommended to me then 5w30, but that seems very Spanish to me, another thinks 10w sends already and depending on the vote would be 10w60 vlt even the better choice (higher speeds etc, I like to drive in itself fast, but not only under full speed, however the C20NE is not blessed with forging pistons or other parts that are suitable for high Drwh numbers) . Who of you can give me a tip or maybe have a similar setup? The previous owner is with the mot or even only 10w40. Should I stick with it?
