Supersession Statement
This PI was superseded to update Warranty Information. Please discard PIP5382J.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition / Concern
A vehicle may have complaints of excessive oil consumption 1 quart in 2000 miles.

Recommendations / Instructions
If you are working on one of the above vehicles with excessive oil consumption of 1 quart in 2000 miles or 1.5 qts
in 100 hours for eet vehicles or more do the following.
Start an oil consumption test by changing the oil and lter, ll the engine oil with the recommended amount of oil
per SI. Start the engine, run it and check oil level, mark the dipstick at the level it shows.
Recommend the customer use top tier fuel (see the latest version of 05-06-04-022) while doing the oil
consumption test.
Not Waiting Long Enough After Running Engine to Check Oil Level Some engines require more time than others
for the oil to drain back into the crankcase. To assure a su cient amount of oil has drained back to the crankcase,
and an accurate reading can be obtained, the vehicle should be allowed to sit for at least 15 minutes, after the
engine has been shut o , before taking an oil level reading. In order to ensure accurate results, the temperature
of the oil should be close to the same temperature as the last time the oil level was checked
Note: Many factors can a ect a customer's concern with oil consumption. Driving habits and vehicle maintenance
vary from owner to owner.
Thoroughly evaluate each case before deciding whether the vehicle in question has abnormal engine oil
consumption.
Please con rm you have properly checked the oil level per Owner’s Manual/SI,
If the vehicle was built with the following engines before the dates listed below and the oil consumption has been
validated replace the pistons and ring assemblies only under the following conditions:
No oil in the dirty air side of the PCV system.
Deposits on the sparkplugs only.
Engine RPO’s with Breakpoint Dates
4.3L Oct 2015

5.3L June 2015
6.2L Aug 2015
If there is oil in the dirty air side of the PCV system replace the LOMA (VLOM) on 5.3L L83 and 6.2L L86 only.(4.3L
LV3 uses a di erent VLOM and PCV set up)
There will be oil dripping out of the PCV tube in side of the intake manifold.

Engine Oil
To ensure proper engine performance and long life, careful attention must be paid to engine oil. Following these
simple, but important steps will help protect your investment:
·
Use engine oil approved to the proper speci cation and of the proper viscosity grade. See “Selecting the
Right Engine Oil” in this section.
·
Check the engine oil level regularly and maintain the proper oil level. See “Checking Engine Oil” and “When
to Add Engine Oil” in this section.
·

Change the engine oil at the appropriate time. See Engine oil life system.

·

Always dispose of engine oil properly. See “What to Do with Used Oil” in this section.

Checking Engine Oil
It is a good idea to check the engine oil level at each fuel ll. In order to get an accurate reading, the vehicle must
be on level ground. The engine oil dipstick handle is a loop. See Engine Compartment Overview for the location of
the engine oil dipstick. If a low oil message displays on the DIC, it is important to park on level ground to
accurately measure the oil level on the dipstick. Idling the vehicle on steep grades for a long time can in uence
the level sensing accuracy Obtaining an accurate oil level reading is essential:
If the engine has been running recently, turn o the engine and allow several minutes for the oil to drain
back into the oil pan. Checking the oil level too soon after engine shuto will not provide an accurate oil level
reading.
Warning: The engine oil dipstick handle may be hot; it could burn you. Use a towel or glove to touch the dipstick
handle.
Pull out the dipstick and wipe it with a clean paper towel or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.

When to add engine oil
If the oil is below the cross-hatched area at the tip of the dipstick, add 1 L (1 qt) of the recommended oil and then
recheck the level.
Caution: Do not add too much oil. Oil levels above or below the acceptable operating range shown on the dipstick
are harmful to the engine. If you nd that you have an oil level above the operating range, i.e., the engine has so
much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine
could be damaged. You should drain out the excess oil or limit driving of the vehicle.
