Ok my 2014 Chevy service manual says change the oil every 7500 miles
I was just watching a video saying that is a waste of money and a gas Moter should be about 10,000-12,000 between changing
And a diesel about 15,000-20,000 on a full synthetic oil ( Schaffer oil) I use castrol GTX Magnatech ,
What y’all thoughts on this ? 7500 to short or 10-12 to long
Wife drives a CTS and drives till the computer says it’s time
So have no idea on her mileage Before the change.
P.S when to change serpentine belt ? I am @ 50,000 and have a brake recall so it’s dealership bound soon
