Looking to use this in my 2008.
Was at Wal-Mart and they had Mobil 1 Fully Synithetic oil in the 5 quart jugs for $22.00.
My Question is they had 0W-30 which states that it exceeds 5W-30 and 10W-30 warranty requirements.
Is suitable for the following GM 4718M and GM 6094M.
Is this O.K. to use and will not void or have any warranty issues???
The 5W-30 they had was for trucks and Suv's it stated that on the label.

acapelladave

use the mobile 1 you are using your car for a daily driver and you need 6 quarts and it should be the mobile 1 full synthetic

bob guzzy

I would use the 5-30 it dosn't matter what is says its for on the label.

AORoads

Mobil 1, 5W-30, full synthetic. That's it. Don't deviate.

I use the same oil as well. In fact I started using Mobil 1 in all my cars.

Any of the synthetics that meet GM 4718 spec. should not void warranty.
I switched to Valvoline synpower because it performed better on the standard wear test than Mobil 1. There are multiple synthetic oils that now meet or even exceed the quality of Mobil 1.

The Mobil1 for trucks & SUV has additives the others don't, is NOT for use in vettes, does not meet GM4718M

The Mobil1 High Mileage is for vehicles that consume oil

any oil that meets GM 4718M and is 5w-30 is good to use
don't make it any more complicated than it needs to be

I think Mobile 1 comes in 4QT [1-gallon] jugs.

does it have those #'s on the bottle

Use only oils that meet the GM 4718m spec so the Truck/Suv is a no go. Viscosity can be more of a choice.

The 0w-30 GM 4718m Mobil 1 oil you found at Walmart is exactly what I use instead of the 5w-30 version which is also at my Walmart. As you read it exceeds the 5w-30 requirements and is a newer more advanced oil. It will not harm the engine or void your warranty although you will get advice on here saying it will. To my knowledge no one on the forum has provied any documentation/proof that the 0w-30 or 10w-30 viscosity has ever damaged or caused a warranty to be voided. Exon Mobil has no fear of that.

The owners manual has not caught up to the new 0w-30 oil in my opinion. The farther north you live the more 0w-30 will be of benefit during cold starts when most wear occurs.

Check out this info from Exon Mobil and others and make your own decision:

what part of: "Do not use any oil viscosity that is not recommended" do you not understand?

you demand proof, yet the only proof you give is your opinion our proof is in the owners manual

the only recommended viscosity is 5W-30, using anything else potentially voids the warranty

Because Mobil says 0W-30 is better doesn't mean it is better, do you believe everything a company says about their product

5W-30 is good to well below -30F, far below the wimpy "cold" weather many were talking about a few weeks ago. It gets that cold here every year and people have been using 5W-30 here for decades.

If it makes you happy, use 0W-30, I could give a crap what you use, I'm betting you are one of those who put in a 160 thermostat because you think it will extend engine life

Maybe I'm wrong but I thought the correct oil was the Mobil 1 Extended Performance (has a gold label) because it has the "supersyn" and claims to be a 15,000 mile oil.

Silverspeed

The extended performance does not meet GM4718M. Don't know why, but it doesn't.

wbear

Woah there partner, why all the vitriol?
Did ya have a bad day or maybe still mad about the game Sunday night?

1. I was posting to John D not you so why the insults. If you don't like my opinion that's fine but you'll have to get over it.

2. John D now has some info to learn from so he can make his own choice along with recommendations in a manual from a company who has made mistakes on lubrication before.

3. Extreme cold weather is not the only reason to use 0w-30. It reduces wear on start up over 5w-30 at normal temps too.

4. Nowhere in the manual does it actually state viscosity is a reason for warranty denial, only for using a non GM 4718M spec oil. Read it again closely. But even if it did this 0w-30 we are talking about meets warranty requirements for 5w-30 oil.
Do you really believe GM would pull a warranty for using this oil?

5. I get a kick out of this statement "you demand proof, yet the only proof you give is your opinion, our proof is in the owners manual"

I posted the info from Mobil in addition to my opinion. Is Mobil all of a sudden nobody? GM recommends/uses their oil, they must think pretty highly of them.

Are not most of the answers on the forum really opinions? I don't see many GM engineers posting here.

Who is our? Are you in a club? Is there someone else signing off on you post or is it just your opinion?

6. Thanks for giving the OK for me to use 0w-30. Can I use 10w-30 too if I want?

7. Actually I don't believe in 160 degree stats but that's again only my opinion.

Sorry for the distractions in your topic John D. Good luck with your oil selection.

Well theres an eye opener! I emailed mobil 1 about this, it will be interesting to see what they say.

Walfart also sells Mobil One 5W-30 in the 5 quart jugs for the same $22 price, I buy it there all the time. I use it in my vette but I change my oil frequently.

I've also been using it in my 4.8L GMC 4WD pickup for the last 100,000 miles of its total 150,000 mile life, the first 50,000 I used conventional oil. I only change it after the DIC say's oil life remaining = 0%, it doesn't seem to burn even a 1/4 quart between changes, and it does not live an easy life.

0W30 flows to critical parts quicker than 5W30 at all ambient temperatures making it a no-brainer choice.

From page 6-26 of the 2010 owners manual:
http://www.montanachevy.com/guide/br...upe_owners.pdf
"• GM4718M
This vehicle’s engine requires a special oil meeting
GM Standard GM4718M. Oils meeting this
standard may be identified as synthetic. However,
not all synthetic oils will meet this GM standard.
Use only an oil that meets GM Standard GM4718M.

Notice: Using oils that do not have the GM4718M
Standard designation can cause engine damage
not covered by the vehicle warranty."

As you stated, the GM4718M standard is the only requirement (first bold emphasis my part, the second bold emphasis is GM's).

PS There are a few GM engineers posting here.

Is this proof enough for you?:

Under "GM4718M Registered Products", Mobil 1 is the only manufacturer with a 0W30 registered for use in engines requiring oil meeting the GM 4718M standard.

When the liability for engine failure is assumed by a company with the reputation of Mobil, I would believe them...did you not read the link provided above where it says "Corvette approved"? 0W30 is better than 5W30 and there is no doubt about that, numbers don't lie. Even at 50°F, it performs better. Is this to say 5W30 isn't good??? Certainly not, it's a great oil too. You might have to take an engine to 200K miles to see a measurable difference between the two so this isn't really anything to get excited about and cause hard feelings between two forum members. Use what you want but know that 0W30 is approved and is better for anybody that wants to use it in any climate summer or winter.

PS The GM 4718M standard doesn't give a specific oil weight, you might want to read it sometime. It does give a kinematic viscosity range and a 10W40 or 20W50 oil does not fall within that range.

Thanks to all esspeciaaly wbear. 0W-30 does meets and exceeds GM requirements. I e-mail them and they said no problem using per GM's insturctions. It no only meets GM requiremnts but exceeds it. Just a note my daughters 2009 VW beetle recommends that she use Mobile 0W-30 in her car also. Just thought I could buy one type and be able to do oil changes on both cars.
Thanks to all that replied. I will be using the 0W-30.

wbear

Glass Slipper. Thanks for posting your take on this oil discussion. I was wondering how many other people had done the research and got turned on to 0w-30.

Its amazing to me how people can be so hard headed and not see something better right in front of them. At least John D is open minded and on the right track.

Its shocking that the highly touted Amsoil is not even on the GM approved list in any grade or type.
