pepper Report post Posted March 1, 2015 My 2011 MKX is in need of a power steering fluid top up. I don't have time to run to the Ford/Lincoln service garage but can pick up power steering fluid at an automotive store nearby. There seems to me to be a mystery as to what I can use other than special Ford Motor Company fluids. Is there something I can use such as Automatic Transmission Fluid or a Prestone power steering fluid that is safe?? Thanks Share this post Link to post Share on other sites

pepper Report post Posted March 2, 2015 Thanks Robert. I was looking for the auto shop over the counter substitutes as I'm not handy to a dealership. Share this post Link to post Share on other sites
Robert Report post Posted March 3, 2015 Some of the generics might have conditioner, which could swell the seals. so be careful about that. Share this post Link to post Share on other sites
pepper Report post Posted March 3, 2015 Drove to dealership and purchased as per the manual so not to take chances. Wise advice, thanks Robert. Chris Share this post Link to post Share on other sites
Galaxy Dancer Report post Posted October 12, 2017 It also might be wise to do a visual inspection of hoses and the plastic fluid reservoir for cracks. I don't think the fluid needs to be topped up. Share this post Link to post Share on other sites
