Sure can. If you have some questions check out BITOG, aka Bob Is The Oil Guy.

 

Can I use Mobil 1 0W-40 GM DEXOS R
On my atsv 2016. I am not sure if we can use dexos r. Please advise. I live in warm to hot weather and run the car hard.

I've been wondering about a 0W40, too. The LF4 does not have cylinder deac. so my guess is going to a 0W40 is ok. I run a 0W40 in some of my V8 engines. I like it because the 0W gets to bearings quicker on cold starts. I'm wondering if a high-end, ester-based, 0W40, like Red Line, would allow me to use the same oil for normal street driving and maybe some tracking.

 

The engine tolerances and the oil pump are designed for 5W-30 engine oil. This is what you should be using.

 

'Preciate your advice. I also was thinking about getting a tune but the owner's manual seems to imply that's not a good idea either. What do you think?

 

yes do exactly as the owners manual specifies

 

Well, older Gen 6 Camaros called for 5W-30. Newer Gen 6ers call for 0W-40 so a change was made. Maybe check with your local Cadillac service advisor?

The Manual.

 

It is best to stick with the oil that the manual suggests for the specific car but I have used Mobil 1 full synthetic 0w40 European blend in many LS engine applications from stock engines to heads and cam cars with zero problems.

 

I have always wondered that if the main reason car companies went to the lightweight oils was to meet CAFE requirements. I know I'd feel more comfortable running the 0W-40 that I put in my wife's GLK350, but I always have run 5w-30 in my GM vehicles per the manual.

 

The 2022 CT4VBW still recommends 5W-30 for the LF4 engine.

 

I have heard that if you are running E85 that you either need to change oil more often OR use a higher weight oil. I'm going to use 10w-30 on my next change as I have it from my old C5Z06. Next oil change will be 5w-30. I also should say that I don't run my car in the cold.

Funny you posted this just today. I had my son's Camaro SS in for an oil change today. When I was in the service bay, I saw a box of Supercar 0W-40 oil next it. Looks like the SS got a fully belly (10 quarts) of this good stuff!

 

That Camaro takes 10 qts.? Wow.

 

The manual.

Yes, 6.2 liter, 376 ci.

Funny, the LT4 in my Blackwing takes only 9 quarts. Yes, again, the manual.

 

M1 0W40 ESP was renamed to 0W40 Supercar, so it will be the Supercar branding going forwards and not the ESP labeling.

Tadge Juechter (Corvette chief engineer) did say they recommended using 15W50 for track days on the Corvettes and the ZL1 1LE over the factory M1 ESP/Supercar 0W40 as they liked the additional stability and lubricating properties of the 15W50 over the 0W40 at the high oil temps seen during track use, but he also said they did not test and validate the 15W50 for street use or long term emissions system compatibility (mostly the impact on catalyst life with the higher levels of ash/ZDDP/phosphorus.) He did say the higher weight of the 15W50 would marginally impact fuel mileage if you ran it constantly. The thread regarding oil use for track days is on Corvette Forum and comes up with a simple google search if you want to read Tadge's reply.

I agree the 0W40 Dexos 2/R oil should work great in these cars and does offer flow advantages with the 0w, especially at lower temps. When I do the break in oil & filter change on my new CT4-BW I'll probably switch to the 0W40 Supercar since it's a GM factory fill for the LT4 & LT1 from 2019-up and also Dexos-R approved, so I'm really not worried about lubricating properties, corrosion prevention, or LSPI issues.

FYI, I have seen dealers use incorrect grades of oils in customer cars if they're out of what is required. My local Chevy dealer was using Mobil 1 5W30 in the new Corvettes for a while even though they're supposed to use Mobil 1 0W40 ESP/Supercar because the 0W40 was unavailable for quite a while and they couldn't get enough of it.

The Mobil 1 ESP X3 0W40 (originally developed for Porsche) would be a good choice too as it's also Dexos 2 approved.

 

M1 0W40 ESP was renamed to 0W40 Supercar, so it will be the Supercar branding going forwards and not the ESP labeling.(snip)

Some of the information out of Exxon-Mobil implies that Supercar was reformulated rather than just a rebranding. Not good.

 

Anyone follow BITOG? Especially pertaining to this topic/oil?

 

Not sure if it’s just subliminal, but my son’s SS drives incredibly smoothly after the service and new super car oil. Seems to drive better than ever. My wife and I took it on a weekend getaway while the boy’s back at college. Not sure how he felt about that! [emoji3]

It needed that Italian tuneup.

 

I give my CTS-V wagon with 6m to my son every now and then so he can make sure it's OK for me to drive, lol.

 

I found out this week that Mobil 1 Supercar 0W40 is simply M1 ESP 0W40 that was rebranded.

 

This makes sense. As I said in a post above I saw a box of super car oil next to my Camaro. The service invoice lists the gm number of the oil type used. It is the same oil that they always used - the ESP.

Here's what I got from AMSOIL. I disagree with them on a couple of points (e.g. using 5W-30 all year round--I'm switching to 0W-30 or 0W-40 for extreme cold). If their ZDDP additive is not intended for Signature Series I don't know where they want us to use it. I asked them that question. I also put a question out to Redline along the same lines.

 

I don't see where a 5 point difference (5W vs. 0W) is going to make any realistic difference in winter cold start performance unless you live in an arctic zone.

 

It's 7.7% thinner at -5°C colder. It's significant. If you've run different oils in the same car you'd know you can feel it.

 

Another reason to live in the south.

 

Yes, then you can use the 0W and deal with all the hurricanes, illegals and tremendous heat. Sounds like a good trade off to me. NOT!!
I'll just stick with what the engineers that the designers had in mind and put in the owner's manual. "If it an't broke, why fix it"?

 

Heck, we just ship our illegals to Martha's Vineyard. And Hurricanes? Yeah, Miami has a pretty good team this year, so the Gators and Seminoles had better look out!

 

However, do not mistake me as Florida Man.

 

And the data collected by engine/lubrication engineers from many companies like GM and Amsoil? Like it was said above from @wanderer54 , "
I'll just stick with what the engineers that the designers had in mind and put in the owner's manual. "If it an't broke, why fix it"?".

I trust the folks who actually dabble in this stuff.

 

Amen.....Thanks jguerdat!

 

Keep in mind the LF4 was probably tested and validated with 5w-30 for lubrication properties and emissions system longevity way back in 2013/2014 during development prior to the release of the MY 2016 ATS-V, and the lubrication testing program for the LF4 was probably a derivative of the validation testing maybe even as far back as 2012 for the MY2014 Vsport cars with the LF3... I don't think Mobil 1 0w40 ESP/Supercar was even available at that time for them to consider and test, even if it is a superior oil and would have been a better oil to use in the LF3/LF4 than 5w30.

M1 0w40 ESP/Supercar being a much newer formulation is probably a superior oil compared to the older 5w30, especially since GM is currently using it in 2 of the 3 highest performing engines they make, the LT2 and the LT4 (the LT6 in the new C8 Z06 is using M1 5w50.) 0w40 ESP/Supercar may very well be totally appropriate to use and perform even better than than 5w30 in the LF4, but we'll probably never get an official confirmation/recommendation from GM for that as it just doesn't make financial sense for them to run a new oil testing and validation program on an limited production engine near the end of its production cycle.

If you want to play it 100% safe as originally designed, stick with the OEM fill of M1 5w30, but I don't think the M1 0w40 ESP/Supercar is going to hurt anything... it might actually perform better, but we'll probably never get an official recommendation from GM to use it.

I should probably ask my buddy in GM Powertrain development to dig around and see if there were any changes made to the bearing clearances, piston to bore clearance, or piston rings when they switched from 5w30 to 0w40 oil...

 

Tapout recommends the M1 Supercar oil for their Brown Belt cars; I was switched to that oil when my car was there. Prior to that, I ran Penzoil Ultra Platinum 05w-30. Before that, I used the factory recommended oil while I had the oil changes covered. At 40K+ miles, Tapout noticed I still had the cross hatching in the cylinder walls, so I can only assume that the AC Delco oil and then the Penzoil oil treated the car well. The car has been driven pretty hard in varying climates over it's life and has been maintained well. I can only assume that the 0w-40 will offer the same, if not a little better protection with the extra additives.

I have noticed that the car runs a little cooler, it takes a bit longer to get to operating temp and the oil temp cools off a little quicker it seems. I also have maybe 2 oil changes a year, so the extra cost for the 0w-40 isn't such a big deal. I'm sure it's fine for stock turbo cars too, but I'm not sure it's necessary.
