I was helping our mechanic at work change the oil one one of our newest trucks, a 2016 GMC Sierra 1500 w/ the 5.3L V8. When the oil/filter arrived from O'Reilly, I thought whoever ordered it made a mistake or intended for the oil to be used on two vehicles. 9 quarts of Castrol Syntec 0w-20 and Wix filter, part number I've never come across before (Fram cross reference is a PH105xx). A new oil filter for the 5.3L, best as I can tell.
I'll be darned if the thing didn't take all 9 quarts to bring the level to full. Curious, I looked in the owners manual of our new (2016) F-350 work truck that has a 6.2L V8. It takes 7 quarts, if I remember correctly.
I always thought the sump capacity trend was going to be a decrease in volume, not increasing. My Nissan Frontier V6 I used to own had a 4qt. sump and was supercharged. It always had great UOA results. The largest truck engines we have in our fleet (not counting diesels) use 6 quarts or less- this includes Ford 6.8L V10's and Chevy 454's.
Anyone know what the potential benefit is to running such a large sump? Especially a 5.3L V8 in a light duty 2wd half ton, a 9 quart capacity seems over the top. There must be a reason why GM increase their own costs (larger oil pan, more oil at the factory), as well as maintenance costs (which all brands are working to decrease.) I just don't see them doing that unless there is some tangible benefit. Perhaps the new emissions controls / VVT / high pressure fuel system increases oil temp? More power = more heat?
