This bulletin is being revised to update model years. Please discard Corporate Bulletin Number 01-06-01-011D (Section 06 - Engine/Propulsion System).

All engines require oil to lubricate and protect the load bearing and internal moving parts from wear including cylinder walls, pistons and piston rings. When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the power stroke, part of this oil layer is consumed in the combustion process. As a result, varying rates of oil consumption are accepted as normal in all engines.

Oil Consumption

The accepted rate of oil consumption for engines used in the vehicles referenced is 0.946 liter (1 qt) in 3200 km (2000 mi).Models:

my Hummer
LL5 2.7l Hummer H3 with 73000 miles on it
weather here is 50 Celsius 122F i use extra electronic fan and thermostat silicon added to be fully open at 80C so my gauge never rich 3 quarter its always half and under 3 quarter only if i use extra load or climb the hill i can see it rich 3 quarter and back to in between the half and 3 quarter

any way after My last oil change 2 months i am now according to trip meter 1242miles or 2000KM i checked my dipstick before i go on a trip to hunt today to see the oil level at L mark the car was on level area the chick is done after 15 minutes waiting for oil to get back to the pan but what to expect it was really in L mark after filling with 0.400 ml oil it came back to the middle of cross mark between the L and the H mark what is the problem with my car does your car H3 with 3.7l do the same ?or its my car burns oil please help me out i don't want to lose my car and the clearance it afford for the off road trips
FYI driving condition vary from off-road and city drive my off-road
I use 10 W 30 acdelco oil for summer and 5 w 30 for winter
any suggestion? thanks in advance
Any one with advice or personal experience????.

 

Looks like it only effects the 2.7L..lmao

I know my '08 3700 does'nt burn any between oil changes every 3k..

 

I think he meant LLR 3.7L?


Mine does not burn any oil at all, and I do not change it until the oil life monitor system triggers and says it is time to CHG OIL at something like 7600-7900 miles. I use Mobil 1 Synthetic.

 

right bro may be its LLR 3.7L i am wrong but any way what grade do you use ?

 

5W-30, just like the manual and oil fill cap say to use.

 

Too much confusion, I dont think he meant .400 ml,that is 4/10 of one milliliter just a few drops. If he really meant 400 ml,almost a half quart,it is a lot, but who knows why?,not me.
Could be that funny "pcv" hose assembly??,thats not really a pcv valve!

 

thanks bro and sorry for typing mistakes my car is straight L5 with 3.7l engine i just corrected the post any way do you recommend me to use 5w30 even in Hell weather which riches 50 and 53 Celsius i just want to ask you is it wrong to use 20w50 acdelco or 10w30 acdelco oil in summer hell time thanks in advance

 

yes bro thats the 400 millilitres is equivalent to 0.42 US quarts i added that much oil to see the oil level back to middle of L and H

Looks like this thread has been dead for about 6years, but I'll post anyhow...
Logged in to see if anyone else was burning oil.

I just turned 110K mi
12 years since i bought it new in sept of '06

I'm burning about a qt every 3500 mi.
CA all its life.
I change the oil every 5K

I'm fine with that consumption after 110K
