Damn, that is some serious stuff to get an oil change done.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

WTF, actually? Good on GM for standing up for their customers when their dealer's minions can't even stand up period.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

Im just so confused.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

Turning into quite the expensive oil change for them! Each of the three changes has and will include all new oil and filters. It's ridiculous, but Chevy is taking this very seriously, as they should considering they designed this car to attract new buyers, many of whom have never purchased domestic before. You lose those customers now and they're gone for good. I think part of the reason they're taking it so seriously is it is not an isolated incident, it's happening all over the country and causing numerous warranty claims. Either Chevy needs to revise the stated oil capacity to be lower [again] or better train the dealerships on the complexities of a dry-sump oil system.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

I just don't understand how difficult it seemingly is to follow a few simple instructions.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

What kind of oil does it get?

Re: Meet GheyRay: Lower, Wider, Lighter!
 

Mind blown. They are a dealership, not a Jiffy Lube, and their "certified" techs still can't perform a simple oil change?

Good on you for getting in touch with GM. I would be beyond furious.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

ACDelco Dexos1 semi-synthetic 5W-30 (made by Mobil). Mobil 1 15W-50 recommended for racing.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

So are they filling it up to the wrong capacity listed on a computer or something, and not even checking the dipstick afterwards?

Semi syn vs full syn? That seems strange.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

Cool. I know Ford factory fill now-a-days is also semi-syn as well (Motorcraft). Well for their normal cars at least, no idea on their performance stuff but assume it's the same.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

Dexos is GM's own "standard" for quality of oil. Its nothing new, its just a fancy word that they license out to oil manufactures so that GM can make more money.

Almost all 2012+ GM vehicles state they need to run "Dexos" oil. I guess they need money to pay their workers for all the recalls.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

Chevy revised capacity from 10.3 to 9.8 quarts last winter, that was mistake #1 for them. Mistake #2 was blindly dumping in 9.8 quarts without taking into account that is total capacity, but getting a complete drain is nearly impossible.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

Yup, I think they're doing it for the extended drain intervals and to squeeze out a little extra MPG while saving on the cost of a full synthetic. Once my free oil changes are done (24k miles) I'll likely switch it over to Mobil 1 5W-30, but in the meantime I'll continue taking advantage of the free oil changes (assuming 3rd time's the charm that is).
Correct, basically a standard above the standard. Many oils meet the specification, but you do have to license the logo from GM to put it on your product so only a few have it. I think this also has to do with the extended oil drain intervals and the factory powertrain warranty; if you're getting your oil changed at JoeBlow Shop using generic bulk oil while still following the extended drain intervals set forth for Dexos1 oils and have an engine failure, good luck getting warranty to cover it.

Is it truly a better oil though? Doubt it, mainly marketing + licensing rights.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

Yeah, Ford also moved to 5W-20, I'm assuming for environmental (MPG) reasons.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

So has Chevy in a lot of their mainstream 4-cylinders; not sure about the V6's. I think the V8's all still run 5W-30 though.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

I just discovered the stock ECU has no-lift-to-shift programming in it...must try this on the way home!

Re: Meet GheyRay: Lower, Wider, Lighter!
 

No lift to shift is awesome!

Starting with 2014, GM's 5.3 and 6.0 (or maybe its 6.2) require 0W20.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

I hate that word require. Is it really required? Or is it just for fuel economy reasons and youd actually be fine (and better protected) with a 30wt?

Re: Meet GheyRay: Lower, Wider, Lighter!
 

The GT500s use a 5w-50. Kind of an extreme range.

Re: Meet GheyRay: Lower, Wider, Lighter!
 

It is required if you want to keep your warranty. If you blow the engine and they find out you didn't us the right oil, they can void the warranty.

Take what you will from that statement. :P
