3RRL: I think your tractor needs Immodium
My Massey 2310 manual recommends changing the regular green antifreeze yearly. It's actually hard to find regular green stuff around here, everyone sells the yellow long life product or orange Dex-Cool rated AF/C.
If heavy duty diesel rated antifreeze has the anticavitation package for wet sleeve engines, is there any harm in using it when regular green antifreeze is called for? Wasting a little extra money is a moot point at the price of the machine. Heavy duty antifreeze is more available here. Isn't this heavy duty stuff purple? Can I use this safely on my 2310?
