Fluids idea

I have been reading these forums for a couple of years. When I bought my Ford 641 with loader in May, I quickly realized that the forty-seven year old fluid recommendations in the manual weren't going to work out.

I did a good bit of reading here and it seems like the fluids folks are using is very varied, regardless of type of machine or manufacturer. Because fluids are so important to longevity, I wonder if there is any research on what’s best, or a single source for a list of what people have successfully used. . If there isn't, it certainly seems like it might be worth having, since the question of what to use in what appears to come up so often. For example, when I checked on what to use in my Wagner loader I found something like six different fluid types being used.

We don't have cylinders that we only use on certain tractors either like I've heard of some guys using. We just use any cylinder on any tractor without concern of mixing different fluids.

I suppose my goal is to obtain some consensus of opinion. Like with most things, the fluid recommendation used by most people is likely the best choice. In another example, I wanted to run the same hydraulic oil in my tractor and Wagner loader. That way, other than engine oil I only have one fluid to worry about. The looming question is what to run, or what works best. Don-Wi’s point about the Oliver being less picky is a perfect supporter of my point, when he mentions one brand being pickier than the other. That is knowledge that comes with (likely) a wealth of experience. I novice trying to learn what to use may get conflicting information which could lead to costly mistakes.I know we will never get everyone to agree on what fluid is best, but I think it could be narrowed down more.
