Man! Just reading those old links about hydraulic fluid shows that there is still strong opinions out there. My theory is that when I look at all of the tractors across America and I ask myself what most of them use I realize that most are like me and want something that will do the job at the best price and not cost me in the long run. I believe that when any product has been on the market for a long period of time without any customer negative feedback then it must be doing the job. Of course every manufacturer recommends their own brand. Ever noticed the manual of ANY new car? But we all know that we use what is available and has a good reputation. So for me I use TSC Travellers because many of the big farmers around here use it and it is a good price. As for the old CC lasting another 30 years I can only guess because I won't be here!
