Does the 2010 5.3 require Dexos?

[mike94silverado]

I know my 11 did, I have a free oil change certificate from the dealership and If it is required I want to make sure they use it. I plan on changing over to full synthetic after this free oil change but figured I might as well use it up since that's what has been in it since day 1 anyways

[DaveH71]

It's recommended you use dexos not required. No manufacturer can make you use any specific oil.

[MS3DALE]

Nope,2010 did not require dexos,2011-up do require a dexos specification oil for warranty purposes.

[MS3DALE]

DaveH71....actually dexos IS required, remember....dexos is an oil specification,not a oil brand.

[mike94silverado]

thanks.... I'm guessing they'll just put regular dino oil in if it's not "required" oh well I'll let em do it then put synthetic in when spring comes

Just run a excellent quality synthetic and drive it almost forever.

that's the plan... I just made the appointment and they're going to put the Dexos in for me (Semi-Syn) hate to waste a free Oil change and it will get me through until spring when I can change it myself to synthetic

Well, somehow GM must have made an error in the owner's manual to my 2013. It adds this little comment to the dexos suggestion.... "or equivalent". Well any oil that claims equivalency to the dexos spec, whether on the "approved" list or not, will work and meet warranty issues. The FTC has recently addressed this, and reinforced their position on the Magnusson Moss Warranty Act, that the OEM has to PROVE that what you were using caused the problem. The burden of proof in on them, not you.

 

That "or equivalent" in the manual covers both you and the OEM. You as long as you use an oil that meets the most recent motor oil standards, and the OEM, because they cannot mandate you adhere only to their internal standard.

 

In other words, everyone relax their enlarged paranoia gland and use a quality oil that claims to meet the current specs... API SN, ILSAC GF-5, and dexos. You stick with any oil that claims it meets these specs and you are in good hands. Whether they are on a list or not is not required. It is pure marketing on one level, and a way to make sure that the consumer is not throwing in oil meant for a 1966 Chevy pickup.

 

As for what oil would qualify, I am not sure there is a straight conventional that makes the grade here. Virtually any oil that claims to meet the dexos standard is at least a syn blend. Virtually any full synthetic is going to make the grade.

I was just wonering if I could get them to put the more expensive oil in since it's a "Free Oil change"

For the FREE oil change, they are going to use their "synthetic blend" oil. If you want the real synthetic Mobil1, they will make you pay for it.
