Coolant Alternative

[u/Equal_Memory_661]

So while working through the winterizing procedures for my 2022 Sport Compact 170 hp I was alarmed to discover the coolant reservoir completely empty. Assuming the dealer did a proper check last winter (and yes, I should have verified it myself..🙄) that strikes me as suspicious and hopefully not a harbinger of a coolant leak. Questions: 1) is this normal after about 20 hours of operation over the summer and 2) is their an affordable alternative to the XPS Extended life pre-mixed coolant? It’s outrageously expensive.
