I have a Freightliner Cascadia truck. There are stickers on the radiator that say that only Purple Antifreeze is compatible with my truck, but then there is another sticker on the radiator that says that Shell HD/N antifreeze is compatible with my truck even though it's probably not purple antifreeze. Two questions:
1. Is Shell Rotella Ultra ELC Extended Life antifreeze compatible with my Freightliner Cascadia?
2. On the sticker on my radiator that says that Shell HD/N antifreeze is compatible with my truck, what does the HD/N mean?
Is Shell Rotella Ultra ELC antifreeze compatible with my Freightliner Cascadia?
