That's a load of bullshit. This car has such a varying oil change interval this claim simply wouldn't stand up in court. I very highly doubt the dealership even contacted GM.
He had told me 5k was the max GM had said it need to be changed.Find out what that service manager claims is the recommended oil change interval. I suspect he's going to say something like 3 or 5,000 miles. The Cruze's OLM won't trigger an oil change alert for 7 to 8,000 miles at a minimum.
He didn't contact GM then. My (optimistic) OLM shows a 10% lifetime drop for every 1,000 miles I drive. This means that my OLM says I can go almost 10,000 miles between oil changes. I don't, but I could and still maintain the warranty.He had told me 5k was the max GM had said it need to be changed.
Whenever someone tells me 3,000 miles, that's my trigger to ignore anything else they say.Find out what that service manager claims is the recommended oil change interval.

My 2012 cruze would have always taken me beyond 10K on the OLM, until I had the emission recall done the OLM was lowered to the 7500 mile range max. My 15 Sonic OLM doesn't go off until below 5% at 7800 miles.He didn't contact GM then. My (optimistic) OLM shows a 10% lifetime drop for every 1,000 miles I drive.

Interesting - the manuals didn't have that emissions recall. It appears part of the recall was to bring the OLM more into line with reality.My 2012 cruze would have always taken me beyond 10K on the OLM, until I had the emission recall done the OLM was lowered to the 7500 mile range max.

Your correct though, as long as you follow the owners manual recommendations, (the OLM) you have met all warranty requirements...
Definitely don't take it back there. Even if GM instructs them to replace the turbo I suspect they'll screw it up somehow.I called GM and opened a case. Said they will call me back.
What's funny is when I first brought it up there he tried to tell me it was just my spark plugs and the boot cover was cracked and that is what was causing the rattle. You could clearly tell it was the turbo.
I'm not sure the diameter of the tube has anything to do with the pipe coking up, wouldn't a small tube increase flow rate and help keep it clear? Just like the dealer I would blame this on the oil not standing up to the mileage the OP was driving, with that said the OP did nothing wrong following the OLM. I however would not use the oil they have been using, at least not at the change interval they had in the past.Good question as to why your oil tube was plugged and another good question as to why it was so thin for such an important job it has.
I wonder if OP has been having the dealer do oil changes - which means it's probably been filled with GM"s semi-synthetic.Do I remember reading on here in the past that the oil feed line cokes up with oil after shutdown since the oil is no longer flowing? Seems this would be more of a problem right after beating on it and shutting down hot or possibly worn out oil oil that can't handle that heat is all it takes?
No, I think allot of the Dexos labelled oil is blends. I honestly don't think those blends should be ran for extended drains in a turbo car, period. I drive 80% highway and even then that oil is well broke down by 6000 miles.Curosity: Is GM's brand the only approved semi-synthetic?
