More info on 0w40 esp mobile 1 for track days and DD

Looks like the 2019 vettes are being filled with the dexos 2 mobile 1 0w40. Do your homework and you will conclude its one stop shop for track day and daily driving. From what I have read its going to be good for pre 2018 motors.

No more second guessing on warranty stuff. The hperlink is coming from GM tech center.

The onlything that sucks it not readily available to buy retail just yet until Q3 this year for the masses.

Great for the Vette guys for sure. But as far as our cars any 0w40 or 5w40 dexos 2 satisfies the warranty fully and is good for both dd and track. And it doesn't have to be Mobil 1. Thats according to my home work and GM official car manual ;)

Ahh yes but its in the fine print on the attachment and the links we can use it on our LT1s for both. I hate swapping out before and after just 1 day on the track.. I want at least run fresh oil before track day and keep in a bit for occasional run to local store or buger joint. Like i did in the gen5. Trying to save on cost but have a little wiggle room and argue my case if this thing goes boom and gm being a stickular on engine repair..

I had no issues of warranty work with the ls3 when I had a fuel sensor go bad on being known to tracking from the dealership standpiont. All I did was take it in within expected time frames for the scheduled times DIC percentage. But changed the oil for sure before a track day. I never reset the DIC and let the dealership do that... record the service performed.

You know what I got top dollar on trade and did make it through the gm certified spec for resale. A guy just bought it and saw it rolling around in my town. This guy has a tracked car and plus has the extended warranty from gm.. By the way I had only 18k for 2015 but it was a good hard driven fun. I expect that out this gen6.. GOD willing:amen:

Or just order today Valvoline MST 5W40 for $5.79

Good deal. I think were not going to see this ESP stuff for awhile. Hell for what price too?

Let me re-phrase:

Up till now dealers would put 5W30 in a Camaro as the recommended oil BUT that oil is ONLY good for DD. Also until recently it was only semi synthetic...
Also up till now no dealer stocked neither 0w40 nor 5w40 so if you wanted the dealer to put this oil in your car you had to bring your own oil supply to them.

Now dealers will FINALLY stock 0W40 (it just happens to be from Mobil 1 vs another supplier likely due to a corporate level deal) and if you choose to go to a dealer for an oil change thats what EVERYBODY will get as a standard Camaro oil regardless if they DD or track the car (vs 5w30). Thats what this dealer memo says.
In effect it says: stop using 5w30 and start using 0w40.

This does NOT preclude anyone from using ANY 0w40 or 5w40 Dexos 2 as specified in the manual and hence fully certified for both DD and track warranty. No small print here and zero concerns about warranty as it is stated black on white right in the car's official manual and as long as the oil is Dexos 2 certified it fully meets GM quality and spec requirements and hence warranty.

Bottom line: lets not confuse the fact that dealers will now (finally!) stock 0w40 dexos 2 and use it vs 5w30 for the said cars vs GM official car manuals which say that ANY 0w40 and 5w40 dexos 2 is just fine. This means the new Mobil 1, Valvoline MST, Motul, etc. are ALL fine.

Moreover, this also eliminates the risk of GM dealer putting 5w30 which is not certified for heavy duty operation yet somebody flogging the car on back roads and the motor going boom. And then GM having to deal with a warranty cost. So the fact they will now put better oil (and charge heaps more for it btw...) protects them from possible motor failures in spirited but still DD situations. It also means dealers will finally stock proper oil for the car regardless whether it is used for dd or track.

i just picked up some torco sr1 5w40 last week gonna try it out. Not dexos 2 compliant but its good stuff and used to use in my old cars all the time

Tongue in cheek right?

Thanks for this, I'm getting some today!

The oil discussions on this forum are always entertaining. There are ENDLESS oil options that will adequately lubricate our engines on the street or track. And Dexos is a Marketing scam for GM to make money. Brilliant from a business perspective, deceptive to end users left thinking it’s some special formulation.

Everything is marketing :)
But all manufacturers use standards to define what oil makes can be used vs not. Lest you and i could sell Canola as synthetic 0w40 and manufacturers would be stuck with warranty bills. Thats it in a nutshell. And if the roles were reversed and you and i built cars and offered a power train warranty, then we too would want to control what lubricates the motors. Well, at least i would!

I use Mobil 1 FS ("Euro") 0w-40. It has a slightly high level of phosphorous and sulfates, which is less-good for the cats, but I run a catch-can, which helps with that issue. Anyway, the regular ("Euro") 0w-40 and the ESP (Dexos 2-compliant) 0w-40 are nearly identical, except for the levels of phosphorous and sulfates.

You can find the Mobil 1 FS 0w-40 nearly everywhere in the US... I used this stuff in my past Mustang and in some of the Lemons endurance cars.

What I don't like about 5w-40 to 15w-40 oils is their inefficiency at lower temperatures; 0w-40 is more useful for DD/track car. In addition, they also have more VI-improvers, which hurt their VI. Example: Valvoline 5w-40 MST has a lower VI than Mobil 1:

UPDATE:
I wanted to add this in: the recommend oil, by GM, for the ZL1 1LE is Mobil 1 15w-50, which is NOT Dexos-complaint and also has higher levels of phosphorous and sulfates like the Mobil 1 FS 0w-40.

Wont disagree that 0w40 is a better option for all 4 season driving and especially in winter. And no doubt thats why GM picked it as it is the most versatile. But for summer only car it really has no advantage over 5w40.

lol of course this is what the torco rep said


We would have to dumb our oil down and pull 40% of the anti-wear protection out of it to even qualify for any Dexos spec. Does not make sense. They are giving you less and charging you more. Shame on them.
