Hi,
I guess for some engines the oil get siphoned from bearing sumps to oil tank especially after certain period of time after engine shutdown. The AMM chapter 12 can give more information regarding engine oil servicing.
My question was not related to the rise of oil level. The oil tank have the same capacity for both engine (same tank). Left engine tank holds more oil than the right engine tank because of the dihedral wing and the interchangeability of engine (position 1 & 2, or left & right).
Back to my question: I am wondering if other aircraft (new & old, Boeing, Airbus,...) have such things ? Please let me know.
Thanks
Regards
