I have a Nissan Almera 2006, the recommended power steering fluid is Dextron III or equivalent as per service manual.
The power steering fluid I had in the system was red in colour, I'm pretty sure it was ATF Dextron II or similar.
However this time around I purchased STP power steering fluid as the store specified it was suitable for most vehicles requiring Dextron II or III specification as well. However whilst performing the flush and opening the bottle up it was yellow in colour.
Should I be worried? I went ahead and flushed the system out with the STP fully. Took the car for a drive and I haven't noticed any issues or noises. Is there anything I should monitor?
