Rare OilBy John Appleman from Beaumont, Texas on October 8, 2011 We have an 8 year old motorhome. When we got it, we had a Howard Power Steering Centering System installed on it which helps keep it going in a straight line. Really helps with fatigue when driving long distances. Recently, a rubber hose slipped off and the hydraulic oil filler leaked out and was lost. I looked all over the internet and at local dealers and could not find the specific oil it requires. That is until Sky Geek......I really appreciate knowing that a supply exists when and if we need more. This formulation can perform at temperatures below -40 degrees f.Pros:It availability and that it is an exact replacement for what my system requires to function as when new.Cons:NothingI would recommend this item to a friend.http://www.skygeek.com/royco-756-aircraft-hydraulic-fluid-quart.htmlBy JR from Houston on February 14, 2011I would recommend this item to a friend.Anderol ROYCO® 756 Hydraulic Fluid MIL-H-5606 - Quart Your question might already be answered below, wouldn't that be a time saver!
