Mobil 1 Vs Mobil 1 MC

[buster]

It's really drastic how these specs compare, between M1 EP and M1 MC oils. $6qt vs $9qt.

Mobil 1 MC 10W-40 20W-50
Flash Points(F) (487) (518)
HT/HS 4.15 5.94

Mobil 1 Car 10w-40 15w-50
(443) (465)
3.9 4.4 (?)

Robust Additive Levels
Recent automotive motor oil regulations have limited certain additive levels, including the anti-wear additive known as ZDDP. ZDDP is an extremely effective anti-wear, anti-oxidant additive, and reducing its level results in compromised wear control and shortened service life. Because motorcycle applications require robust additive systems to control wear and oxidation, use of an automotive motor oil or an automotive motor oil re-labeled as a motorcycle oil compromises protection and performance. AMSOIL Synthetic Motorcycle Oils are overtreated with robust additive packages, including high levels of calcium, phosphorus, zinc and additional oxidation inhibitors, to extend oil life expectancy, provide unmatched engine cleanliness and greatly reduce wear.

MC oils are using the same levels of Moly and Boron (275ppm) but 1,800/1,900ppm of ZDP

So if the MC oils are then friction modified, could they be used in a high HP car such as a Z06?

Buster, do you really think that a $9.00 MX4T or 20w-50 would be worth running in a car? I've ran the MX4T in a ZX-9R with good results, but later switched to the old red cap becasue of the cost!

Some of us picked up M1 motorcycle oils at AutoZone for $1
