For reference here is the results of my 22 model 5.3 after 37k miles. I've been lazy and change the oil when the DIC shows 2% which works out to be about 7,500 miles. South TX, mostly 75mph highway between Austin and Houston. At each oil change I am amazed how little oil this engine consumes and the catch can only has an ounce which almost makes me regret purchasing the J&L canister extension.
Using Kirkland Signature 0W-20 Full Synthetic with whatever filter is on sale at the store.
I am a bit surprised they are asking for a 10k interval on this engine, I don't think I will for warranty / lifter purposes but its good to see the oil could take it.
