I checked my service papers. It says, "Removed oil pan cleaned and resealed lower oil pan added oil checked for leaks none present." It says the sealant is 12346286.So did they actually drop your pan, spend a lot of time cleaning off the old sealant, not only on the pan but on the engine block itself. And are you as could as a robot to put an even amount of new sealant on? It needs a very steady hand.
If it's "Dexos Approved" you would think it would contain an amount of syn. oil that would meet that standard.The problem with synthetic blend is that there is no standard. They can put a drop of synthetic oil in with dino oil and call it synthetic-blend. I would not go more than 3000 to 5000 miles with the oil. You should be fine.
I don't think the dealership had a choice on which oil to use. Warranty repairs have to be done very much by the book, including using GM's preferred fluids.I took my 2013 Chevy Cruze to a local dealer today and was shown to have a leaky oil pan gasket, which was repaired under warranty. I forgot to tell them that I use full synthetic oil and they filled it back up with synthetic blend. Will this cause any problems and if not, how soon should I have oil changed back to full synthetic and new oil filter? Dealer offers a pretty good price on full synthetic and filter change. Are dealer synthetics as good as Penzoil, Mobil 1 etc?
Thanks
What is the dexos standard? Is there some technical data that describes the standard somewhere? I have never been able to find any technical data on dexos oil.If it's "Dexos Approved" you would think it would contain an amount of syn. oil that would meet that standard.

I think a full synthetic 4 qt. oil change at my preferred dealer is $69.95 ... or maybe that was with a coupon
I don't understand what the standard is but since Dexos is a GM designation, oils using it must meet some standard....you would think at least.What is the dexos standard?
