Do any of you Ducatistas know if the pink Ducati Eni coolant is compatible with Silkolene Pro Cool coolant? Mine is slightly below min and I want to top it up before riding to my nearest Ducati dealer to get some of their stuff. Silkolene's website claims it is, but my understanding is it's a propylene glycol based coolant, which differs from Ducati's branded stuff which I believe is ethylene glycol based. Not a chemist and not keen to mix if it could cause harm.
