I got a '14 R/T Blacktop. Need to flush and replace my power steering fluid. I know the MS-11655 fluid is recommended since the car used the EHPS system. Dealership gave me MS-9602 fluid, which is basically regular fluid, and when I returned it, explained I needed fluid for the EHPS, they gave me MS-90030 electric power steering fluid and insisted it'll work, which I'm a bit skeptical about. Can anyone tell me if that fluid will work? Just want to know before I make the drive back to the dealership for the 3rd time this week.
