changing fuel additive

2017 TD6

I've been running EDT, after watching this video, I'm switching to Diesel Kleen, It has no potassium. ( potassium is in coolant, will show blown or blowing head gasket)

Thanks for the info! Since the only downside to potassium is possible masking of a head gasket leak, I'll be sticking with Opti-Lube XPD, which is far superior to the others in lubricity. If I ever decide to have my oil analyzed I'll switch to Diesel Kleen for a couple of tanks before sending the sample.
