XJ 40 Power Steering fluid

Hey team, I need Power steering fluid to top up the reservoir on my '93 XJ 40. Is the fluid readily available today compatible with the original spec fluid? Or do I need to source the original spec product?
Thanks
Mike

Luckily you’re in Canada so just go to Canadian tire and buy some motomaster generic dexron 111

this stuff I think will do ya
