Engine oil and filter

Safety

• The dipstick handle may be hot.
• Oil above or below the cross-hatched range can damage the engine. If the level is above the range, the caution says to drain the excess or limit driving and have the excess removed.
• Failure to use dexos1 oil can result in engine damage not covered by the warranty.
• Do not add anything to the oil. Oil-system flushes are not recommended.
• No drain-plug torque is in the pages read.

Symptoms

• A low-oil message on the driver information center is a reason to park on level ground and read the dipstick. Idling on a steep grade can throw the reading off.
• The dipstick handle may be hot. The warning says to use a towel or a glove.

Diagnosis

1. This page uses the June 20, 2014 printing. English capacity for the 5.3L and 6.2L is 8.5 qt, and the metric cell is 8.0 L. A later service bulletin is sometimes cited as changing the quart figure. That bulletin was not read here, so this page does not replace the printed manual figure.
2. The 2020 book prints 8.0 qt for the 5.3L L84 and the 6.2L. That is a different manual. Do not 'correct' this 2015 page to match it.
3. The 6.0L V8 in the viscosity section is the heavy-duty engine. Its cooling row is labeled 2500 and 3500. No 1500 oil quantity is taken from that engine.
4. Diesel trucks are sent to the Duramax supplement. No diesel oil quantity is copied here.

Tools

• Clean paper towel or cloth

  Wipe the dipstick, push it back in all the way, and read it with the tip down.

Specifications

Steps

1. 01Read the dipstick on level ground

   If the engine has been running, shut it off and wait several minutes. Pull the dipstick, wipe it, seat it fully, and read it with the tip down.

   1. Use a towel or glove on the handle.
   2. A low-oil message still requires level ground. Idling on a steep grade can affect the reading.

2. 02Add one quart if it is below the cross-hatch

   Add 1 L (1 qt) of the recommended oil and recheck. Do not add so much that the level rises above the cross-hatched area.

   1. 4.3L: SAE 5W-30 dexos1. With-filter capacity 6.0 qt (5.7 L).
   2. 5.3L and 6.2L: SAE 0W-20 dexos1. With-filter capacity 8.5 qt (8.0 L) in this printing.
   3. The with-filter capacity is not the amount to add when the engine was not drained.

3. 03Keep the 2015 figure on the 2015 truck

   Do not replace 8.5 qt with the 2020 book's 8.0 qt unless you are working from a GM document you have read for this VIN. This page has not read that document.

   1. Below −29°C (−20°F), SAE 0W-30 may be used in the 4.3L and still has to meet dexos1.
   2. The fill cap location is an engine-compartment figure. It is not redrawn.

Common mistakes

• Changing 8.5 qt to 8.0 qt because a 2020 guide or an unread bulletin says so.
• Pouring 8.5 quarts into the 4.3L.
• Using SAE 5W-30 in the 5.3L or 6.2L as the normal grade. Those engines are SAE 0W-20 in this book.
• Adding an oil flush or an additive.
