Which grade are you guys using in your hydraulic system.
Original fill was 7.1 in cars made in and prior to 1991, then newer 1992 and on, original fill was 11S.
Anyone here convert their 7.1 systems to 11S?
I questioned my technical guys on the matter. They say the 11S was an upgraded product. They feel you can flush the system of the 7.1 and refill with 11S.
Their confidence tdid not over-inspire mehmmm, hence the question with what is your experience to date on this matter.
