M5 (S62 engine) produced from 3/00 and all Z8
The S62 engine incorporates redesigned piston rings from 3/00 which permit the use of BMW High Performance Synthetic Engine Oil SAE 5W-30.
The recommended engine oil for all Z8 vehicles and M5 vehicles (produced from 3/00) is BMW High Performance Synthetic Engine Oil SAE 5W-30.
The race bred engines incorporated in BMW M vehicles include increased power output and maximum engine speeds compared to conventional BMW engines.
Due to their high performance design characteristics all M engines may exhibit slightly higher oil consumption compared to conventional BMW engines.
A spirited driving style (especially during the critical engine break in period) will lead to further increased engine oil consumption.
BMW recommends checking the oil level and if necessary topping up using the correct viscosity whenever refueling is required to maintain the value of your BMW throughout its service life.
BMW High Performance Synthetic Oil is recommended where BMW Special Oils had been recommended in earlier service information.
The oil change intervals should not be extended due to the greater durability of a fully synthetic engine oil. The engine oil and filter should always be changed as per the vehicle's Service Indicator when the "Oil Service" or the "Inspection" display appears regardless of the type of oil being used.
BMW mineral based High Performance engine oil is also offered for model year 1998 and earlier BMW models. For reliable engine performance in all temperature ranges mineral based engine oil viscosity must be matched to the temperature range at which the vehicle will be operated.
