1) Synthetic oil 75W90 is recommended for commercial duty (corresponding to the requirements for GL5 oil).
2)
Early production drives were filled with engine oil and have that recommendation in the Owner's Manual. Late production drives have ATF
oil filled. We recommend the use of ATF oil. Observe strict cleanliness so that dirt is not drawn in by the oil.
NOTE! Never mix ATF oil with engine oil, as this will cause foaming and possible pump failure.
3) The tightening torque for the three thinner bolts (two long and one short) is 15 Nm (10 lb. ft.). This applies to all drives.
