Mine used a bit less over interval than Mobil. I liked it just moved to another brand to try and stop the oil consumption. Nothing wrong with either brand. My truck is just different I guess. Zero consumption with valvoline extended protection and zero with amsoil SS.

big thank you to everyone who’s pitched in info,opinions and a laugh or two on this thread. Now to see if it consumes the rotella gas truck at the same rate.

Hit 4800 miles and was a quart low. So decided to change it. Swapped brands and tried some rotella gas truck to see if there’s any difference in consumption.

It’s a big ol brick for sure but the truck does tow it very nicely. I’m curious the difference in the components for the camaro and the Silverado engine wise. I’d feel a lil better with a 5w-30 at least and a 0w-40 would be my choice given the option. I wonder if the variable oil pump makes this...

Seems ridiculous. I wonder what the difference is if any in the block,oil passages etc. I’d feel much better with a lil heavier oil. But I guess I’m just gonna have to follow the recommended oil weight.

Low from the Max (Full) line.

Disabling the afm is definately on my to do list at some point. I really don’t have any complaints on the truck I love the pep and power. I’ve been around plenty of the 6.0s in my line of work and being thirsty is about the only gripe I hear on a regular basis. We have a few of the 6.6 gassers...

Oh I’m not happy about it in the least! But it seems to be the norm with the active fuel management on these trucks. That’s another reason I’m looking to try a different oil that maybe has less oil consumption. I’ve seen several instances of oil consumption with the mobil 1 EP as well. If memory...

Picked up the truck in November and did the first oil change through the dealer. Second oil change I did myself and discovered I had used 3/4 of a quart over 5500 miles with the factory gm oil. I refilled with Mobil 1 EP 0w-20 and a Mobil one EP filter. I’m pretty sure I’m over analyzing this...
