Switched both my 95 Bonne and 00 GP GT to regular green coolant. I change it on a regular basis so no issues so far. As long as your LIM gaskets have been changed it should work fine.

I run regular old Valvoline in both, and Wix filters. Never will a Fram touch anything that requires an oil filter. 214K on the Bonne and 314K on the GP GT.
