Except for the M1 Racing costing between $16.00 and $22.00 a quart (albeit GREAT, but
very low starting TBN oil, so maybe not so 'great' for street/long OCI use) depending on where/how it is purchased, does NOT make this a viable economic choice to just use up some GTX, and it STILL might not meet Dexos 1 specs,
if that is a concern.
Actually, M1 Racing 0w-30 has high TBN ( 10 ), detergents, moly, boron, zinc, all that. Yes too expensive though. See
"Mobil1 Racing 0w-30 Virgin Oil Analysis VOA" ........I'd only use it a half quart or quart at a time, sparingly, mixed with other oil to boost it only; zinc is so high it would cause corrosion if used long term straight.
Are you
sure about that TBN, as I remember something about Mobil suggesting VERY short OCIs with this oil, but I could be wrong about this.
Maybe it was just that they stated NOT to use it as a street oil due to the corrosive levels of ZDDP in it's add pack.
