Keep your eyes peeled here, as when the time comes someone always starts a thread announcing it. Note that although Walmart never shows up on the rebate "Participating Retailers Include" list, those purchases do qualify, although in the past Amazon has not.

There has to be a difference, because the new 0w40 has the dexos2 certification while the European 0w40 does not. So that alone means they cannot possibly use the exact same formulation. Also, the ESP Formula is a low SAPS oil, so it's level of sulfated ash is considerably lower than the European 0w40, and it has a lower TBN. You can see the different technical specs on the Mobil 1 website. I have also seen a used oil analysis from Blackstone labs on the new 0w40 and it's additive package is different than the European 0w40, it has much less calcium, it has more magnesium and it has more boron in it.

Just wanted to give HorsePowerAddicts a shout out as I ordered their 10-quart 0w-40 ESP Dexos deal for $118.75 shipped anywhere in CONUS on Sunday,
they shipped it on Monday and I received it today. Being they were including the shipping cost in their price I expected to get it in a couple weeks, not in one day.
I also like that they sell it on quart containers as opposed to the liters which most are selling for a little less.
Allows me to change my oil over the Holiday weekend. Thanks HPA for the quick service.

Really? I still don't see this new oil in any stores, so I have to go through my dealer to buy it. Still not seeing how this benefits GM at the consumers expense? Why isn't this oil available in stores yet?

Then say some guys says, screw it, I'll just use 5w30, then he has an issue with his engine, and GM says, 'well, you weren't using the right oil, so we're denying warranty coverage'. Another possible benefit to GM.

Almost a year in and this oil is still hard to get - that's pretty freaking unacceptable and pretty damn fishy if you ask me.

Patman

They can't deny you warranty coverage for using a dexos1 5w30, it even says it's acceptable in the 2019 owner's manual.

JMII

I was about to post the same thing. Its not like the engine suddenly changed in 2019. Thus older C7s can run the new oil and newer C7s can run the old oil, either or... its all good. The main reason per Mobil's press release is the 0W-40 was authorized by GM for dual use (street and track).

I also betting that I'm safe in terms of warranty coverage with the oil I'm running, which is Mobil 1 5w30 ESP Formula, as it's dexos2 certified.

Curious what exactly you think the benefits are from switching to the ESP oil? Not having to replace your cat converters? That's a huge contributing factor to GM switching to the ESP formula, which stands for Emission System Protection. GM recommended that people use 15w50 for track use, which results in premature cat converter failure, which is covered under multiple emissions warranties (for up to 8 years or 80k in many states), which costs GM money. Now you can use an oil that has less catalytic converter harming additives, which protects the engine a little less ( but power train warranties are only 5 year/60k), but saves GM money on warranty claims for converters.

If nothing else, the forums have done a great job at perpetuating the feeling that YOU receive some great benefit from switching to the new ESP oil.

Patman

The ESP formulas can definitely prolong the life of the cats, but they also have the added benefit of keeping the engine cleaner, something very important for us with our direct injection systems that are definitely prone to building up deposits. I also like the fact that both the 5w30 and 0w40 versions of ESP Formula are dexos2 certified oils, which means they both have an HTHS value of 3.5 or higher, something of importance if you like to push your car hard when the oil temperature is higher (either on the track or even on the street on a hot summer day) That extra level of "cushion" from the higher HTHS will contribute to a much longer engine life, IMO.

I still don't believe GM switched to this oil in order to appease the very tiny number of C7 owners that actually take their cars to the track, as I bet that number is less than 1%.

As an aside, if the price of this oil is still too high in your area (or you can't find it) but you want to get the benefits of a dexos2 certified oil, another option is Pennzoil Euro L 5w30, which can often be found in Walmart for around $23 for a 5 quart jug. I might just give that oil a try in the future in mine.

The HACK

Also, again, NO AFFILIATION, but I just picked up 10 bottles of Valvoline MST 5W-40 from NAPA, which is ALSO DEXOS 2 certified. If you need a 40 weight oil because you DO track, or drive a lot in a hot environment, and don't want to wait until the Mobil 1 0W-40 is widely available, they were $4.99 per bottle if you reserve online.

They meet (and exceed some) most of the Mobil 1 0W-40 specs, meets and certified by DEXOS for DEXOS 2 standards. The one drawback is the zinc and phosphorus content is slightly lower by about 10 parts per million, which means the anti-wear additives are slightly lower. For a modern engine that doesn't exceed 10,000 miles between changes, that 10 PPM difference in the antiwar ZDDP won't be harmful to the engine.

For now that's what I'm using until the 0W-40 is widely available. This from someone who ran 10W-60 Castrol TWS, which was $12 per bottle RETAIL, for over 10 years in his car because BMW DOES void your engine warranty if you don't use that specific oil (for a while, anyway). They don't even bother to use the word "recommend." They SPECIFIED that you must use Castrol TWS 10W-60 because of the super tight bearing tolerances AND the 8,000 RPM redline.

Patman

Don't worry about the lower levels of zinc and phosphorus, as all the major oil companies have dealt with these lower ZDDP levels by increasing the level other anti wear additives in their formulations, such as titanium and boron. So that Valvoline 5w40 is another great choice if 0w40 ESP Formula is not available.

The HACK

Thanks, that's what I suspect. Before I bought it I looked at a dozen sites talking about Zinc and its anti-wear properties and came to the same conclusion. Especially for NEW engines it's really not an issue.

Mostly it's just a pretty good deal, 10 bottles for ~$50 and meets DEXOS 2. That means I won't have to swap oil for the events I'll be attending NEXT year. Yay me.

Be careful this price you showed is for the European formula which is different.
