I have to change it soon and already have 1.5 liters SAF-XJ I can't use (because it's the non FM booster) |
1M comes from factory filled with differential oil without the FM booster which means you may continue with this regular oil as long as you are comfortable with the noise in your car. If you refill with the oil including FM booster then you need to continue with that one and you can't go back to non-FM booster oil though. That's the trick you need to pay attention to.
Since I am satisfied with the regular oil without FM booster and am also concerned about a possible future unavailibility of the one with booster, I myself prefer to continue with the regular oil, for now.
Which type you actually have in your differential?
