Thanks Paul and Drummy,
from the
Australian Antarctic Division and BAS websites I see that various types of Foremost/Nodwell and Hagglunds transport units are in operation at those stations. As it's a local company I'll contact
Foremost and ask what specialty lubricants or tranmission/transfer case heating systems are being used. A lubricant that would be fluid at -90 to -80C and still have sufficient viscosity to lubricate at probable operating temperatures of +40 to +100C would be interesting. Cheers, from Canada.
