A couple things: I don't have a wet sleeve engine or head gaskets that =
leak. No mayonnaise.
I run about 195 for water and about 230 for oil.
On a cool day, a sump heater or good warmup is essential. Same for tires =
and brakes.
I just repaired a couple tractors with milkshakes in the trans and diff; =
not good. And Joe, one was my Oliver 1650, great tractor!
Cheers, Bill
