Can I mix my own DEXOS blend?

[MrDatabase]

Is it possible to blend Chevron Supreme GF-5 with mobil 1 - say 50-50 and get a satisfactory DEXOS blend? Why? cause I have a case of Chevron I'd like to use up.
Chevron isn't on the DEXOS licensed brands yet.

Thanks.

Honestly, you can do what you want... as long as it isn't poured into a car that is under warranty...

If it is under warranty and requires DEXOS, I'd avoid the temptation to be cheap and save a few bucks on each oil change while it is under warranty.

But either way, it's your call.

 

[MrDatabase]

Yea, your right. Hate to waste good oil.

Short answer no, but you could in theory make a blend that could pass DEXOS. I personally would just use Chevron and change my oil at 5k and sleep well at night.
Better yet give the Chevron to me I will make sure it has a good home.

Why would GM even bother to attempt to deny the warranty? It would cost GM more money to attempt to provethe consumer and Chevron where the cause of engine failure than to honor the warranty.

But then again this is GM.

I doubt GM would feel obligated to prove to the consumer that it wasn't their fault.

While under warranty, you should be careful to keep all paperwork and triple check everything. Everybody has a horror story on this.

GM doesnt NOT require DEXOS1. They recommend DEXOS1 and an oil of equal quality may be used if DEXOS1 oil is not available. It could create more headaches during warranty if you did not use strictly DEXOS1 oils, but theyd have to prove the oil was the cause. The 2013 Silerado OM even says you can use a 0w-30 in cold weather, and there aren't any DEXOS approved 0w30s yet.

This is why I try hard not to keep a "stash" or buy much extra oil ahead. I was always trying to use up either outdated or a no longer wanted oil my cars.

+1 on not having my "stash" at my house. My "stash" is on the Walmart shelf. If Walmart had the oil I use on sale I might buy extra, but I am not going to buy oil on sale if its not the exact oil on sale.

From http://aoca.org/resources/have-questions-about-general-motors-dexos

Q. If I don't use a GM-licensed motor oil, will my warranty be voided? A. No, federal law prohibits a manufacturer from requiring the use of a specific brand in order to maintain the warranty. The FTC recently issued a consumer alert to remind consumers and businesses that the manufacturer or dealer must prove that a given product caused the need for repairs before denying warranty coverage on the basis of the product simply being used.

It is also worth noting that GM itself has acknowledged alternative engine oils may be used if dexos is unavailable: In the event that dexos approved engine oil is not available at an oil change or for maintaining proper oil level, you may use substitute engine oil displaying the API Starburst symbol and of SAE 5W30 viscosity grade. Use of oils that do not meet the dexos specification, however, may result in reduced performance under certain circumstances.

What vehicle is this going into? If it's a port-injected V8 in a pickup, mix away since the chances of an oil-related failure in those engines is quite low. If it's a DI and/or turbocharged engine, use full synthetic 5w-30 and change it religiously.

I think one of the reasons GM went to dexos1 for their gas engines was to simplify things at the factory and at the dealer to reduce oil-related mistakes. dexos1 is plenty good enough for a 5.3 V8, and satisfactory for a 1.4T I4.

Costco has chevron on sale for $2 a quart. So that's why I have a stash.

There is one, an Idemitsu dexos1 0W-30, licensed globally, but good luck finding that.
