2014 chevy Silverado active fuel management
Have been reading on the net. People say that active fuel management uses oil. My question is has this been addressed in the 2014 chevy Silverado 5.3. Or the one's that are complaining about the active fuel management useing oil abused there trucks. Just wondering. Love this truck just turned over 2000 miles. Best truck I have ever owned first chevy truck. Traded a 2011 ford f150 5.0. For this truck like this truck a lot more then the ford. Anyway just wondering about the oil. Thanks

I don't think anyone (other than maybe a GM quality control engineer) can answer your question.
It appears, that the 5.3, with AFM, burns (read consumes) more oil than other GM engines that do not have AFM.
Some consumption has been fixed by changing valve covers; but, if that is a problem, why would the problem not be in the 4.8 engine which uses the same valve covers?
Has it been fixed in the 2014 trucks, I don't know.Ray

There is no honest answer to your question, I doubt you would even get a straight response from GM on this one. Some have issues with AFM and some do not, seems to be more of an issue with years prior to 2010 ish. Ray makes a valid point about the valve covers. Myself, I don't use the AFM by way of the range technology device, and I love it, prior to the use of this device I had not noticed oil consumption in my 2011, As for 2014, I would hope if there was an issue that is/was wide spread that GM would have addressed this by now. The safe answer is watch your oil level and you will know.Life is short compared to history

I would mention.....have you seen or heard that General Motors plans to Recall 370,000 units of its Redesigned 2014 Full-Size Pickup Trucks, Citing a Software Problem That Could Cause Engine Fires??
GM said the Recall Affects All of the 4.3-liter and 5.3-liter Trucks the company has manufactured since production started in the summer, including 303,000 trucks in the U.S. and 67,000 in Canada and Mexico.

Since the "LT" engine is new for 2014 there isnt any history on this new engine. The complete engine is new and uses Direct Injection.
Time will tell.
