yes just check the pcv vlv it should be a screw in style, instead of the push in , type if so, you no doubt have the new eng, and that is not bad oil usage at all , i use staight dino grease of 5-30 and it do,s not use oil at all, previous eng at 58000 mi started using oil at the rate of about 1 qt per 800 miles , since eng change ---OO--.we think we have had oil problems just talked to a friend of mine a a very large caddy dlr and he say they are having a big prob, with the north star engines using oil and GM will not fix them untill they go below the 1000 mile per qt mark,, good luck with your truck just keep the oil changed and the filter a good brand and the pcv vlv every 25-30 thousand miles and you should be fine Jerry
