Has anyone changed power steering fluid from red type to green (correct spec Tutela GI/R) and had their rack fail soon after, especially cars with higher mileage? I'm contemplating changing my fluid to GI/R. Car has 114000 miles on it and the steering can feel ever so slightly juddery when parking, though i have none if the frothing fluid symptoms. Reservoir is the updated version. What concerns me is that if i change the fluid to the thinner green stuff i might end up with a pile of leaks that the thicker red fluid didn't escape through. Anyone changed the fluid on higher mileage cars and had problems? Cheers.
