Which may be the case. Maybe Shell M-1375.4 is the base, Mercon SP isn't far off from that base,and LG6 family has and additional additive which makes it a "higher grade" of M-1375.4. Something that may confirm such is whether or not the barrels of OEM and LG6 fluid state "Made in Germany" or "USA". Maybe a call into Shell is required.
