Engine coolant

[Lex2007]

According to Mazda parts counter (Dan at Ourisman Mazda in MD) any Speed3 produced *after* December 17, 2007 uses FL-22. Before that it *does *not use FL22. AllData contradicts this, and states I need FL-22.

AllData isnt incorrect but there is a caveat. As per the TSB 01-033/07 in the above post, you CAN use FL-22 on older Speed3 but dont mix it with orange coolant because it will turn black.

Dan sent me this Mazda Fluids Chart updated March 16 2019 is as follows:



Pentonsin PENTOFROST A2 (GREEN) Antifreeze Specially Formulated For Asian Vehicles — CONCENTRATE- HOAT technology but does not have FL-22 according to the rep I spoke to at PENTOSIN but it does cross reference with Mazda 0000-77-501E-02.

Pentofrost A3 (BLUE) does have FL-22, according to the same guy at Pentosin but is only available in 50/50 mix but does NOT cross reference with Mazda 0000-77-501E-02 (confusing).

I had little trust in the expertise of the guy at Pentosin...he knew nothing about what FL-22 specs included, only that MAZDA had no cut off date for the need to use FL-22 or not. He was wrong about the cut off date.

Pentofrost A1 (RED) is FOR ASIAN vehicles, CONCENTRATED, HOAT technology but isnt listed for MAZDA.
