We’re trying the Greens Care Plus. I called the folks at Terresolve, who make it and it sounded great.
We’ve been getting about 1000 hrs out of the regular fluid and the main feature of the Synthetic Plus is that it can last up to 2 X’s as long. It would be great to get those results although the cost of the oil isn’t the big benefit there. It would be mostly in the labor and time involved.
We ran it two days straight and nothing unusual. I’m not sure if I expected it to turn orange or what but it ran just like a clock. This summer will be the big test.
It went so well in this one, I ordered enough for another. If they still hold together then I’d like to try it in our fairway mowers. This does not cost twice as much as the standard bio fluid but to get 2X’s the life in those machines with their increased capacity would be a nice savings.
And if it turned out to be a better fluid..
