2013 GMC Sierra first oil change....3000miles
The mech tells me that it needs dexos...never heard of it.
He tells me that he uses another brand with dexos but not the AC Delco brand itself.
The onboard computer says that I am "62% through the life of my oil"......suggesting that the truck should be changed at 5000 miles...as many synthetic oil changes are...
The manual calls for 7500??
it also says that "if the onboard computer resets accidentally, have an oil change within 3000 miles of your last service..
It all sounds like conflicting info and I have NO idea what to make of all of this, but:
A) I plan on keeping the truck for a loooooooong time
B) I don't want any warranty BS problems...
Can anyone make sense of all of this please?
