Everyone here is ASSUMING that these engines are gonna be trashed at 100k, burning oil, smoking, running horribly. I think you are all just hating DI. I bet you did the exact same thing when they first started using MPFI.


So Nick how many Ultra 5w-30 UOAs have you seen go this low in ONLY 5,000 miles? Any lab...

You CAN label me a DI "hater" because of things like this UOA (and others). Also for the deposits on the valves. And the cost of the injectors over "normal" injectors. And so on.

Sorry to inject FACTS instead of defending hopeful marketing issues. But I've NEVER seen a NORMAL engine do this to any oil in only 5,000 miles. And look how the OP operated the engine. Much better than normal people drive their vehicle.

Its interesting to see how people LOVE UOAs when it makes their cause look good (cause = brand, engine, etc) but when it makes their cause not so good then UOAs are the devil.

Sorry I saw (and prob owed) my first Fuel Injected engine WELL before you were born. Loved it for 394,000 miles (TROUBLE FREE AT THAT)

And this 5w-30 sheared more than a "little". More like a TON.

So when you post your UOA on anything Nick you BETTER call out that its inaccurate and means nothing.

I'll stand by my comments....

Seriously...

Bill it seems you and I read, and heard the same info regarding these engines. I took a lot of heat a while back for my comments about the fuel dilution. Not to mention anything else and start that mess all over again. LOL Many DI owners don't see this as a problem, funny though because if it were a FI engine they'd be suggesting doing leak down tests and pulling injectors.

I'll try my best to avoid the technology as long as possible, it won't be easy though. But maybe by the time I'm ready and forced into DI technology these issues will be history. As always time will tell.

The OP bought this vehicle in good faith, figuring that GM had done their homework.
Maybe not.
GDI will either be further developed to the point that it really works in service, or it'll be dropped as a failed effort.
I expect that we'll see further development, much of it the result of the beta testing done by owners like the OP.

My boss has a 2009 Chevy Traverse with the 3.6L DI and he's got just over 80,000 miles on it. He hasn't had any issues with the motor as far as I know. I've followed him before and I do notice it seems to put out some smoke when accelerating from a stop. He goes to the dealer for oil changes and follows the OLM. I assume they put some bulk oil in it.

A lot of comments here, some valid some not.

All that matters to me is that OP went by the OLM (many owner's won't take it down to 0% out of fear) and his wear metals look GREAT.

If he keeps this up the engine will last forever.

I'd like to think you're right, but these engines are definitely a lot tougher to maintain and make last over a standard FI engine.
Nonetheless, looking at wear metals this sample was pretty decent I'd say.

I do wonder how a lower quality 'dexos' oil would hold up...or when Joe Schmoe goes to the quicky place and gets bulk dino. Those vehicles may be less then desirable to own as the second and third owner. For me, we have 100 k warranty and will probably have the car for about 130-150 at most unless our current circumstances change.

I dont hate DI.

I know you cant get accurate Fuel Numbers without running an actual test not SWAGGING IT. A certified lab got over 5% (twice) on the same sample Blackstone called a "trace".

I wouldnt be a bit afraid of that ULTRA / OLM 0% combo. Seems like it deals with the fuel just fine.

I think GM already took DI into consideration as thats why they are still running 5W30.
