I looked at him and said really, in 5000 miles since last oil change, he says yup, they burn oil. Im thinking I have never had this happen with a newer car. Sure enough, pulled the stick and nothing.

Next step, he says leave it so we can see if it needs to stay overnight for service, alright then, off I go. He calls me back and says it needs a new timing chain and sensor of some kind, two days, is what it is.

When I picked up he told me they see this all the time with the new D.I. Engines. Loose low friction rings allow more oil past to get burned up and sent our the exhaust, gets worse with miles. He also added I should check oil level every 800 miles or so which I have done. Sure enough its using oil, two quarts in 4500 miles, now how the heck is that better for the environment?

Sometimes it seems two steps forward and the steps back. On the other hand most of what he said could have been b.s. but there are many online stories of the same experience.

I don't believe this, as needing those would mean the Check engine light would be on.

I had it happen twice under warranty on a 2009 Traverse 3.6L V6 DI. You could hear the timing chain slap and the Check engine light was triggered.

I got rid of it before it could come back again and then be on my dime for an engine out timing chain replacement.

I asked the same question about the engine light not coming on. He said that there is no monitor for low engine oil lvl, no light, which I fould a bit odd. But then again, I have no experience with low oil with past cars.

Low tension rings = more oil consumption. It has nothing to do with the type of fuel you use.

My ex wife has a 2009 Buick with the 3.6 DI. I told her to have the thickest oil available put in it when she gets oil changes. It burns oil at a considerable rate for a car under 75,000 miles. It also had an injector stick open under warranty that thing smoked like a pig getting it to the dealer. I don't see how that engine has done any good for the environment.

My 2010 Tahoe has 158k miles and burns no measurable amount of oil.

There is no connection between DI and oil consumption.

Not according to the service manager. ;-) At any rate this engine is consuming oil just added a quart as it was barely touching the stick.

The Oil issue and the timing chain stretching/sensor are 2 separate issues.

Mine which was the 3.6 V6 DI engine didn't have any low oil issues but the timing chain stretched enough to throw a code.

Chevy knows about the problem, that they extended the warranty period for the issue. Though it happened to mine about every 20K miles.

I got rid of it before the warranty expired since it is an engine out repair on the Traverse.

You help this engine's ring seal and reduce carbon deposits by driving this vehicle hard. Driving them softly, especially in the beginning, is not good for them.

Like any new technology, there are problems at first but then the issues get solved. DI is no different.

Engines don't have oil level sensors installed, they just have low pressure sensors. And you have to get your engine oil VERY low to trigger that.

And my pre-DI Canyon, very well cared for, burns about a quart every 3K miles.

I think most here missed this part.

They don't all do it, but they do seem to be much more prone to do so.

5w-20 oils don't help either.

my viper(2005/100K) drinks oil like a camel too water. But other than that it is a great engine and have had zero issues.

i think the problem is a) GM Product b) Lite Oil c) Ring/Liner tolerances by design
