On the center dash info screens, mileage pages, sometimes I see a V6 to left of the screen then sometimes I see V4. What is this?

Well I learned something new. I always though it was odd changing from V4 to V6, I never made the connection of Eco. thought it had something to do with a software version. Thanks for the info.

I believe your Blazer needs to be in motion to see the V6/V4.
