Whats up guys i got an 06 V with the ls2 ,,,, its currently got 68,000 miles and im losing about 1-1/2 quarts of oil every 2500 miles ,i would say im a conservative 50% of the time and a spirited driver the other 50% ,,,, is this normal?? i have no warrant either , anybody have an idea ?

The bulletin from GM states that if the LS2 (not sure about the other LS engines) sees higher than 3k rpms for a sustained amount of time then 1qt of oil every 3,000 miles is normal.

My stroker consumes an average of 1 qt every 1000 miles.

My ls2 consumes oil but it is nothing that alarms me anymore. If you do a lot of 3k+ driving like heavy said, or do a lot of engine braking, it will consume more. GM will only do something if you burn more than 1qt every 2k miles. Yeah it's a ridiculous amount but that is the way it is. If you're burning more than that, then you have a problem and should get it checked out.

Get a catch can setup. Then at least you won't be eating it.

Hm-m ...

My LS6 sips MAYBE a tablespoon every 3k miles.

I have one, still consuming copious amounts of oil.

I bet I could get it to consume oil. LOL

Never passing 3000 rpms = no oil consumption. Got it.

My LS2 spends a great deal of time north of 3K RPM...sometimes continuously (driving north of 100mph)...and so far it has not had consumption issues. On my last OLM-based OCI (from 100% to 5%...don't know the mileage) it didn't need any top-up oil.

Mine was the same way. Added an oil catch can and the oil consumption seems to be normal.

Granted I just had the motor rebuilt due to a spun bearing.

I just added a little under a quart to mine. Thats 3k miles including a trackday.

Never passing 3000 rpms = boring

Yet again you guys come through. I have the exact same thing with mine. I drive mostly highway and some city on the weekends. I am sure during normal acceleration I'm above 3k and I surely mess around with other cars on the turnpike. I have noticed that (going by my oil life percentage) I need to add just under a quart when I get in the high 30% range. I then don't have any other problems until the next oil change. Thanks for the info

"top it off and move on. as long as it's not smoking you're ok".

The end

.....and even if it is smoking.....it'll be alright.....

thanks for all the great replies!! so does anyone know the reasoning behind the consumption ? , and being that we have the vette motors, do we inherit their oil-ring problems?

Where do you get this from?

Oil-ring blow-by was a problem but is not inherent in "vette" motors (the LS2 is a truck motor also).

As for yours, maybe a ring problem so it is really a matter of you getting the thing apart and checking if it isn't sucking oil in through the breather.

Try not doing the "spirited driving" for the 50% of the time you claim you do for a few thousand miles (if you can) and measure the useage.

You might add a catch can and see if oil is in fact being sucked into the motor.

Also, it may not be rings at all.

Although this bulletin talks about different motors, it does apply:

I just turned 100,000 miles on an 06. Never have to add oil with 5 to 6K oil change intervals. I engine brake all the time. Magnaflo sounds great on decel. Shift at 2800 to 3500 rpms routinely.

How many of you guys actually check the dipstick between changes?


How many of you have also seen ufos or bigfoot?

Well I am 2600 miles into my last oil change. I drove the Dragon, hard, and other western NC mountain area roads last weekend and I just checked my oil: it's right at the top of the dipstick. Perhaps it's been said but I believe the LS2s are more prone to oil consumption issues than the LS6s in these cars.
