Here's an attachment that shows the engine oils that meet the 2010 Terrain GM6094M approved motor oil specification.
I plan on using Mobil 1 for my first oil change at 4000 miles and after.
I was wondering is the OLMS could be flashed on the 2010 Terrain to utilize the new Dexos 1 oil specification?
It is my understanding that the Dexos 1 spec. replaces the GM6094 spec. and there is no change in the Terrain engine in 2011 versus 2010.
Just wondering.
:help:

Just use any name brand syn oil. Some brands pay for the certification and some don't, but they all meet all GM specs.
