Yup get supertech from Walmart. It is generic mobil1 synthetic made from the same plant. I never go by the light I just change mine spring and fall gets me about 3500 miles before the light even comes on.
not even sure if they use mobile 1 at the chevy dealer - they never say anything other than synthetic or Full synthetic oil on the write up
I know on the dealer advertisement they say something about ACDelco dexos1 and the regular oil but both are a lot cheaper than the full
synthetic (about 40-50% more)
The manufactures advertisement for ACDelco dexos1 has an advertisement that is confusing - part of it says it's full synthetic and the next
sentence starts talking about the synthetic blend -
I just read a little on the Acdelco dexos1
Sounds like it was a new standard for 2011+ vehicles and still is a GM Mobile 1 oil
Anyone confirm this?
Wonder why the new cars are using the dexos1 standard and not Mobile1
or are they really the same thing?
Ok so I read up and it sounds like Mobile 1 is the same as Dexos1 - full synthetic
