Mobil Extended Performance Oil meets GM 4718M
Although they do not advertise it, Mobil Extended Performance 5W-30 Oil meets GM 4718M.
I asked them in an Email and they replied,
"Thank you for your inquiry,
The Mobil1 EP 5W30 motor oil will also meet the GM 4718M requirement.

Thank you for choosing ExxonMobil products.

This oil has more additives and a higher TBN, should be better than regular Mobil 1.

Mobil's own site does not list EP 5w30 as meeting the Corvette specs, as it does other Mobil 1 oils. Nor does the GM site list it as an approved oil that meets the Corvette spec. But, the Mobil & GM sites could be outdated. Did they say when it was approved?
