If you have an oil leak bad enough to show on the ground I'd take it in for a check. Most likely this will be covered under the power train warranty.
I hope my Cruze makes it to 265k that's awesomeI experienced this same leak at the throttle body starting at about 90 to 100k miles. The leak slowly increased over time and at about 265k miles I decided to attempt to have it repaired. My air intake manifold was replaced and its possible your valve cover will also need to be replaced. There is a bulletin out for this. The repair certainly caused the leak to stop for a while and eventually it started to leak again but only a small amount. I lose about 4-5oz oil per 6k miles but I dont know for certain if the oil loss is caused by this leak only.
I suggest taking it to the dealer and having them take a look at it. If I can find the bulletin number I will post it. If you decide not to take it to the dealer if its the same leak from the throttle body I experienced.... it didnt seem to have any major impacts on the vehicle over hundreds of thousands of miles. I did however eventually notice a slight decrease in performance closer to the 225k+ mile mark.
Im glad you are able to take away some information from my previous post. After reading my own post even im having a difficult time comprending my own words.I hope my Cruze makes it to 265k that's awesome

Dexos is more prone to sludge up than Mobil 1 - it's a synthetic blend. Especially considering the Toyota 3.0/3.3 is known to be a sludge pump (on conventional oil) and is just fine if you use a synthetic oil in it.Took it to the dealership this morning they said I was using the wrong type of oil (Mobile 1 Synth) and it sludged up the PCV valve amongst other things which made it leak.. They are replacing the pcv, cleaning a bunch of stuff and putting in dexos synth blend. I used Mobile 1 in my heavily modded Trans Am and my V6 Camry never had any issues.. Seems a bit sketchy but whatever.. Long as it gets fixed and it's covered under powertrain warranty
Call GM and file a case with them. Demand that a case manager call your dealer and educate them on the use of oils that meet dexos1 specifications. Mobil 1 is leaps and bound better than the semi-synthetic oil they put in there from the factory, which will in fact sludge up even faster as jblackburn pointed out above. I recommend finding another dealer.Took it to the dealership this morning they said I was using the wrong type of oil (Mobile 1 Synth) and it sludged up the PCV valve amongst other things which made it leak..

They usually use Mobil 1 as the "full synthetic" choice at GM dealers (it's what Corvettes use).Do Chevy dealers offer the option of a full synthetic Dexos 1 oil such as Pennzoil Ultra Platinum? Or just the AC Delco synthetic blend? If they don't offer an "in stock" full synthetic Dexos 1 oil, will they put yours in for a fee?
Hey Bluefirestarter,I get the oil changed with Mobil 1 every 5-6k miles and I do a lot of highway miles. The service guy said it’s not a GM recommended oil and shouldn’t be used. He also said I’m lucky they are going to cover the repair because GM could have turned it away for improper equipment. Not Happy at all at this point.. I loath this dealership but went there because I wasn’t sure how bad the damage was. How can I file a case with GM about this? This is the same dealership that told me it’s okay when my car idles all over the place because that’s how these cars are.. turns out it needed a transmission rebuild.. the worst! I was so excited about the new wheels I bought for my Cruze but this turned into a buzz kill
