Approvals: FIAT FIAT 9.55550 CONTRACTUAL TECHNICAL REFERENCE N°F426.E06Alfa Romeo's recommendation for the following cars
- 159 / Brera Spider 939 2.4 JTDM 20V and 3.2 V6 JTS 24V Q4,necessary quantity for one rear differential oil service about 0,75 litres
necessary quantity for one PTU / transfer case oil service about 0,6 litres
The two aggregates will no longer need a regular oil service if you believe Alfa Romeo's maintanance plan.
The oil which is filled into the two aggregates during the production of the car is considered to be a "lifetime filling".
Nethertheless it is recommended to replace the oil after about every 80.000 km to remove all the abrasion which accrues during normal use.
