2024 Duramax Oil Capacity V8. 2 of mine run delo 5w40 year round and the newest one i'm trying the ultra low ash delo 600 adf 15w40. But the oil capacity decreases to 9.2 quarts without a filter change.
I have done probably six oil changes on my ’17 duramax, and it takes exactly 10 1/2 quarts to be at the top of the crossmarks on the dipstick. Always consult the ownerโs manual of your vehicle for the exact capacity of oil.
