Thanks for all the information. I sent my wife to Tractor Supply with a note to pick up a gallon of Heavy Duty precharged green antifreeze for diesel tractors. She gave the note to the Tractor Supply person and he gave her a gallon of "Travellers Universal antifreeze and coolant" The container says nothing about use in diesel tractors or precharged for initial use. It has no instructions about diluting or if its prediluted! I called up Tractor Supply and the person said they had no idea what precharged was or if this stuff was heavy duty! I am concerned that this "Travellers antifreeze" is not the right antifreeze for my diesel. Anybody ever use this brand?
