Tu fais une vidange tous les 10 K ?
J'ai trouvé ca la "procédure officielle" : http://www.bmwz8.us/pdf/zz-Engine_Oil_Check.pdf
"Engine Oil Level Check Procedure:
S62 S52, S54
1. the engine must be at operating temperature 1. the engine must be at
operating temperatur
2. let the engine idle for at least 15 seconds
2. turn the engine off
3. turn the engine off 3. wait at least 1 minute
for the oil to drain down
into the sump
4. wait at least 1 minute for the oil to drain 4. check the level using the
down into the sump dipstick**
5. check the level using the dipstick**
Notes:
All vehicles must always be parked on a flat surface when checking the engine oil level, it is
recommended to always check the level whenever refueling is required.
This will ensure that the proper oil level is maintained throughout the life of the vehicle and during
the critical engine break-in period (approximately 5000 miles) when the engine may have a
tendency to consume slightly more oil.
*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. Check the temperature
viscosity chart in the Owners Manual or Operating Fluids Manual for further information.
** The space between the two marks on the dipstick corresponds to approximately 1.1 US quarts (1
liter). Do not fill beyond the upper mark on the dipstick. Excess oil will damage the engine."
Et pour le sujet passion d'un autre Forum : Il confirme que la Castrol TWS est identique à Castrol RS .
C'est chiant leur procedure,c 'est comme les porsche.
D'ailleurs, que veut dire ''temperature 1'', ca correspond a quoi ?
De quoi parles tu au sujet de l'huile identique, RS vs TWS ? C'est la meme huile, mais la formulation fut repense pour la E46, donc c'est plus vraiment la meme ? Je ne comprend pas ou tu veux en venir avec le sujet passion ??
