not recommended. Diesel engines are mainly iron block/iron head (talking about big rigs such as Detroit Diesel, etc. and not VeeDoubleUs, etc.) and they call for different service requirements (per operational characteristics, metal compatibility, etc.).
If your gasoline engine runs on glycol based coolant, check your manufacturer's recommendation and stick to that. Otherwise, you'll get into trouble.
Yes you can use it. The diesel coolant has SCA additives in it to help prevent liner pitting and other types of corrosion.
The GO-5 coolant you guys rave about also has the SCA added.
The big trucks are using aluminum components just like cars. The diesel coolants are generally overkill for a car, but the diesels are not having electrolosis problems or Dexcool disasters like cars do.
Every car that comes into my shop for a flush gets a diesel coolant with SCA's unless the customer requests something else.

Thats fine. Make sure that you flush out the old coolant and use distilled water.
GM was using green+SCA in their trucks until Dex-Junk rolled around. I see no problem with it - unless the diesel coolant is destined towards a Honda or Toyota product, neither one of them wants nitrite, borate, or silicates in their coolants.
