Figured with my preceeding post it would be appropriate to bring this topic bakc up for discussion. I have a gallon jug of Valvoline MaxLife Dex/Merc which specifically lists Mercon LV on the back, was going to use it while doing the clutch in the Mustang but for some reason that just keeps on working well. Might just as well use it up if I can. Here is an older thread about the topic, but a couple years have past. Looks like the discussion kinda left off with "I trust valvoline but it doesn't make a ton of sense. Maybe the mercon sheered more and ended up at the same viscosity?"
Here is the spec sheet on Maxlife: http://content.valvoline.com/pdf/maxlife_atf.pdf
Mercon LV spec sheet: https://www.fcsdchemicalsandlubricants.c...MERCON%20LV.pdf
Mercon Lv vs. MaxLife
cSt @ 100C is 6.0 vs 5.91
cSt @ 40C is 29.6 vs 28.82
VI is 155 vs 156
Flash point 216C vs 202C
Specific Gravity @ 60C 0.842 vs 0.843
Clearly the basic specs are compatible. The question is, is the MaxLife as good a actual Mercon LV in the real world? I will be doing ATF drain and fills with my engine oil at least a couple times, and I don't need to take two steps forward just to take one step back with fluid choice.
