My fuel heater is leaking and I'm wondering if anyone is running without it in cold weather; like a few weeks ago it was -20F and with the wind chill was -40F.
I went to the dodge dealer and he said that atf +4 had to be used in my nv4500.
He said it superceded the old oil and when he typed in the part number it kept coming back to the atf +4 so I'm wondering if I can use it.
