I just changed the lube baselining the Taco using Redline. FWIW, seems Redline changed the color of MT90 sometime in the past few years. I had one bottle of old stock from probably 2008 which had a faint red tint and the current stuff no longer does, it's just gear lube yellow like the regular 75W-90.
