Is all brake mineral oil the same?

[Deleted member 26715]

I bought a kit to bleed the sons Magura rim brakes but I need a little bit more oil, they are still a little spongy, the oil is blue mineral oil, I have some Giant MPH red oil, can they be mixed or am I better off ordering some more blue oil? this was the kit I bought http://www.ebay.co.uk/itm/182033834539?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT

AIUI Giant Red oil is DOT type fluid, whilst Magura "Royal Blood" (silly name) is mineral oil, so mixing them will cause Bad Stuff to happen to your seals. Cheaper alternatives to Royal Blood are available (power steering fluid I think). @Yellow Saddle is probably the person to ask.

Thanks Tim, I think I may have some power steering fluid but will wait for @Yellow Saddle to confirm, although @'s don't seem to work
