2012 Chevrolet Silverado 1500 Owner Comments

problem #6

Jul 302018

Silverado 1500 LTZ 5.3L V8

  • Automatic transmission
  • 94,699 miles


Checked all the fluids before a trip. Oil couldn't tell on the spiral stick. Took to the dealer after trip and they said oil was low, only after I asked to check prior to changing. So now I know my 2012 Silverado LTZ 5.3L is using oil between a 4mo/4k oil change. Dealer never has said anything about oil usage or why is does it. Dealer maintained since new, according to dealer. I take to dealer for oil changes. Now I have to worry about my oil between changes and ask for the dealer to tell me the level prior to change. GM is going to lose a family of customers!

Update from Oct 11, 2018: GM wants me to take to dealer for check.

I have taken to the dealer for every oil changes and some other checks.

I want to know about the oil usage between an average of 2700 miles oil changes.

Check engine light came on. With 29% engine oil life left. Had to add 3 quarts of oil. No leaks.

Noticed I'm not the only one with problem.5.3 engine.

Update from Mar 26, 2018: Replaced valve cover & PVC> Still using 1 quart of oil per 1000 miles.

Silverado 1500 5.3L V8

  • Automatic transmission
  • 95,352 miles

Engine uses approximately 3 quarts of Valvoline max life 5W-30 dex-os approved oil between 3000-5000 miles, when I change oil. Originally was throwing code that spark plug was fouled per dealer. I replaced all spark plugs with new ac delco plugs. Less than a month later it threw foul code again. Dealer proceeded to replace valve cover, citing Chevy bulletin that claimed it would solve problem. Has not fouled plug yet, but still using excessive amounts of oil. Now has 124538 miles, idles rough, and slow acceleration. I have to check oil at every fuel up just to make sure I don't go low. How can Chevrolet allow loyal customers to suffer with these problems?

Silverado 1500 Z71 5.3L

  • Automatic transmission
  • 42,120 miles


Bought vehicle used. Did not expect this type of problem, so did not check oil as I should have. Took in for oil change, discovered almost no oil in engine. Low oil light never came on at all. Watching close since then and have to add a quart on oil between 750 and a 1000 miles. For a low mileage engine (42K) this is way to much. I also own a 1995 Suburban with a 5.7 and 249K miles, still not using any oil. Love the Silverado, just hate the excessive oil consumption.

Silverado 1500 LT 5.3L V8

  • Automatic transmission
  • 8,000 miles

I purchased a 2012 Silverado. My first oil change the truck didn't have a drop of oil in it. It burns 2 quarts every 3000-3500 miles. I have been doing oil consumption tests and finally the dealership removed that carbon from the engine which they stated only works 2 out of 10 times but its the first step before GM will let them rebuild the top end of the motor.

This issue stems from the fuel economy aspect of switching from 8 cylinder to 4 cylinder operation and there is blow by and the oil burns off. There are many people experiencing this and I don't understand why there has not been a recall to fix the issue considering it is prevalent on a specific motor GM produced.

Hard to find any company that stands behind their products anymore and GM is certainly one who doesn't unless you go through a ton of BS to finally get them to take responsibility for their worthless workmanship. I now have 42000 miles and still have issues and continue to do these dumb ass oil consumption tests until it meets their guidelines. What a crock. I'll never buy another GM truck.
