what kind of oil should i put on my car, 10w40 or 10w30, i am in massachusetts..........i put mobil one, but dont know what kind i should put in?

 

I think the spec is 10W30 synthetic It doesn't have to be mobile one but it has to be synthetic.

 

It has to be Mobil 1 0W-40, European Formula. It will say MB 229.5 on the back. No other oil that meets the spec is readily available in the US.

There is a new Mobil 1 5W-40, MB 229.51 that dealers are starting to use. It's required for new diesels and there's some discussion about whether it's a good idea to switch to it for other late-model MBs. It's probably ok, but it's not easy to find except at dealers anyway. Best bet is to stick with the 0W-40 229.5. Any other oil, including Mobil 1s, will void the warranty.

 

WTF!! Void the warranty because of a brand of oil?? There is not a single document you can produce to substantiate that legally..

Oil for these cars can be purchased at Wal-Mart... Why are you giving out this information when it is absurd ?

Anyhow, you didn't notice the he has a 2000 model right? And a used one at that. So,, Why in the Hell would he ,,, anyway... nevermind.


The same quart of Oil your nice dealer puts in your car costs less than half per quart at the corner store... But its your car and your dough...LOL..
Keep it "OEM"... LOL.

Could you give me some info on the specialized Mobile 1 refinery that Mercedes owns? I'd like to invest.....

 

You can put whatever you want in your car. But the recommendation is MB 229.5 and Mobil 1 is the easiest one to find.

Mobil 1 0W40 is hard to find>>?is that ok for winter?

 

It's the best for ALL weather conditions period. Use it!

 

I use royal purple 5w-30 or 10w-30 on my AMG.

 

Why? As you can see in the MB spec sheet (my link above), -30 oils are explicitly not approved for AMG engines (page 3 footnote). The fact that no Royal Purple is approved is almost beside the point. You're using a viscosity that is called out as inappropriate for your engine. What's the point?

 

True.. I must be using 10w-40 for the AMG then.. I know I purchased within spec. Anyhow, 75% of those approved oils are European market product. Royal Purple is sure better than Mobil 1. I got all my friends using Royal Purple and they really like it better than Mobil 1.

 

i decided to purchase 0w40 mobil one synthetic from autozone..........

 

To be honest,,, its better to continue to use what ever has been in there before if you know what it was.. Usually there is a sticker somewhere unless it was done privately... Abrupt changes in viscosity's used to be a no no with synthetic on cars with a lot of miles...

 

i only have 66k on mine....

 

quick to jump down the guys throat for passing out the correct info.If you don't use the mb spec oil it will void the parts of the warranty affected on a car still under warranty.Sure it is out of warranty now but the same shear properties in the mb spec oil still apply to the used engine.Use anything other then the approved oils and you play with short life or failure.Amsoil is not one of them unless as noted you are out of the states.gamble if you like to,I would not with a 10grand+ motor.Royal purple?you are rolling dice,the mb spec helps long bearing life and cam surface life.

Walmart has mb spec 0w40 napa has it on sale a buck off last time I was there,autohausaz.com has the fleece filters for about 14 bucks and mb spec ELF synthetic in 5 liter jugs for about 34 bucks per 5 liter jug. shipped free on orders over 50 bucks.you need two jugs
why gamble with such a nice engine?
from the horses mouth(factory)and if the car is under warranty you can bet in cases of engine failure if they have not been the ones who did the maint intervals,they will test the oil and void the warranty and leave you holding the bag
"Flexible Service System If the engine oil used
does not meet the above mentioned
standard, engine damage is possible,
which is not covered by the Mercedes-
Benz New Vehicle Limited Warranty." That is the single document that is all I need to make sure i use spec oil in all of our new cars.


"Anyhow, you didn't notice the he has a 2000 model right? And a used one at that"
anyhow you did not notice it is a 2002 ,and not that used with only 66k miles barely broken in!!!

 

This must be my week for people to argue with me online about B.S. I dont even care about..LOL

1. Its still a used car not under warranty 2000, 2002, or whatever. The voided warranty statement was what I was addressing.

2. Show me one single case where a car UNDER WARRANTY was denied a warranty claim because the owner decided NOT to pay the dealer for an oil change and suffered engine failure which was found to be the result of not using whatever oil the dealer was using at the time which resulted in denial of a claim. Just one....

You can't because you and i both know that is B.S.

Do you even change your own oil??

All I was saying to Whoover was that it doesn't matter where you buy the oil or who puts it in. A warranty cannot be voided as a result of using "some other" brand Oil. MERCEDES does not own any refineries and CAN NOT Mandate to a customer which BRAND of oil they MUST use in their vehicles..

I could give a crap what the little FSS note says.. That's not the LAW.

Also, while you were venting, You could have referred the rest of your post to whomever it was for because it didn't apply to anything I said.

What you do is your business but as for me, there would be trouble in paradise if a dealer tried that crap with me.

I think its really sad that you folks have nothing else better to do that to inflame a simple post with all of your fire and brimstone warnings over the simplest stuff. OIL??

Spend a little more time under the hood, you'll get to know your car a little better.

Bye now....

 

Nobody but you said the warranty would be voided because of the wrong brand by itself. Mercedes does say (and I linked the document) that the warranty doesn't cover engine wear that is caused by not using MB sheet 229.x oil of certain viscosities. The only Mobil 1 that meets 229.5 is European Formula 0W-40. Furthermore, only certain brands meet those specs, and the document I linked lists them. This isn't rocket science.

If you want to ignore the MB specs in your engine, feel free. If you want to recommend that someone else does, you should probably point out the possible liability. It only seems honest. Putting the burden of proof on a third party (me) to cite a warranty claim that MB dishonored because of non-spec oil makes little sense. I wouldn't want to assume the possible liability because five people in a forum don't have any first hand knowledge of such a case. If you think the "law" protects you from MB claiming you violated the warranty terms because the oil you use didn't meet their engineering specifications, you should cite the law.

The amount of work I do on my own cars is also irrelevant. As a matter of fact I do enjoy getting grease under my fingernails, but so what?

 

You guys are killing me.. Stop it already... its over okay.. change the subject.

Geez..... this could last forever and why? there is no engine damage, no warranty lawsuits, nothing but a guy standing in front of his car wondering
"Hmmmm what kind of oil should I put in this thing?"

This conversation has gone waaaay beyond pointless so I'm going to be the first to throw in the towel here... Any folllowers?

 

lets stop the arguing, i put 0w40 mobil one.......and the car is running smoother THANKS FOR YOUR ADVICE 0w40 fully synthetic is the WAY TO GO..........

 

I was Shop foreman at a dealer, when an engine warrenty claim was denied because MB proved the oil in the motor was not Mobil 1 .
It was an S55 than had lost a rod bearing at only 12k miles. MB came to investigate, took and oil sample and denied the claim (oil had been changed at a quick lube/costco/sears place) MB did not say the oil had caused the problem, but got out of the warrenty because of it.

If you run any other oil, you are running risks, poor quality oils effect the PCV, EGR, Air injection as well as lubrication.
While it is true that MB do not own any oil companys, it is also true that Mobil do not make cars, but they develop product together. MB and Mobil, Ferrari and shell, engineers, spend millions of dollars and thousands of hours developing lubrication standards and systems, I doubt anyone here knows more than they do. Why risk changing recomended products to save a few buck's. You don't have to go to the dealer for Mobil 1, but i would not put anything else in a clients car.
Oh and I have spent plenty of time under the hood !!

 

did you NOT read the part about throwing in the towel on this conversation??

WHAT MORON WOULD TAKE HIS S55 TO QUICK LUBE AT 12K miles?
I didn't even know they did Benz's...LOL

Thanks for inserting the fact that MB just used that as an excuse to get out the warranty but could NOT conclude that the reason a $110K car's engine failed at 12K miles was because he went to jiffy lube. There is no doubt much more to this story I would hope for the sake of the owner but quite frankly, I'm not interested in hearing it..

Please lets this go people..... its done. We are all going to do whatever we want regardless of which side argues what....

 

Seems like a lot of guys like Mobil-1 here. I used it for a while in another car years ago but have been running AMSOIL in everything I own for about 15 years now. I use the 0-30 in my 01 S-55 AMG and my wife's 04 Lexus, 03 Explorer, and my 06 F-150. I use their motocycle oil in my 02 Harley. I have never had a problem related to oil and like the extra protection and longer drian intervals that this oil provides. It is especially good in cold climates and eliminates slow starts and the clatter that you hear at start up with other oils. They have a web site: AMSOIL.COM. I wrote to them when I got my Mercedes just to make sure I could use this oil without any warrenty issues and they said no problem. I also noticed a small improvement in my gas mileage, about 1 to 2 miles per gallon.

 

I think you need Mercedes to say no problem, not Amsoil.

If you click the link I posted earlier in the thread, you'll see (page 4, footnote) that 0W-30 is expressly not allowed in AMG engines. I'm glad you haven't had any problems, but you're taking a risk ignoring the viscosity specifications for you car.

 

Yes, I saw the oil recomended by Mercedes that is why I asked the Tech Reps at AMSOIL if I could use the 0-30 oil that I use in everything else or the 5W-40 oil that AMSOIL makes for European cars. My thinking was why have several different types of oil if one can be used for all. The 0-30 oil is more expensive and has a smaller wear scar on the chart than the 5W-40 oil therefore it offers better protection and it says on the label that it can be used in all gasoline engines so I thought it would be fine. The Mercedes chart did not list AMSOIL 0-30 oil or any other grade of AMSOIL but maybe that is because it is not a well known oil. I did call and ask the techs though instead of emailing them and since reading your reply have decided it would be a better idea if I sent them an email and asked the same question again. Maybe the idea of knowing there will be a written record of the question and reply might change the answer, it will be interesting to see. I am not sure how much of a difference in viscosity there is in the two but the 0-30 offers the best protection of all the oils AMSOIL offers and maybe that is why it can be used evn though it is 30 weight oil. I will let you know what I hear from them.

 

FYI, 0W-30 is much thinner at high temperature than 0W-40. (The first, W, number is cold or "Winter" viscosity and the second number is operating temperature viscosity.) Brand aside, the AMG engineers have specified their engines need the heavier viscosity at operating temperature.

There is no universal wear measurement. But an engine is designed with a particular viscosity of lubrication in mind. Things like main bearing clearances, rod bearing clearances, piston-to-cylinder fit, piston velocity and lots of other specifications go into the viscosity requirement (and vice versa). It's a pretty fundamental operating parameter.

 

Well I heard back from my email to AMSOIL. This is going to be lengthy and somewhat technical. I have to say to start that you are mistaken in your comment that there is no universal wear measurement. The wear measurement that was mentioned before was supervised by the American Society for Testing and Materials and is a four ball wear test # ASTM D4172. AMSOIL conducts this test on all of the different viscositys of oil it makes and also tests other oils as well. AMSOIL oils have lower wear scars on these tests than any other oil, and 0-30 oil has the lowest wear scar of any oil tetsed. Also there are many independent oil studies and tests that rate different oils by their viscosity index, that is their abilty to remain viscous at operating temperatue. Although AMSOIL 0-30 was not rated in any of the charts I could find, several AMSOIL oils were. On every test AMSOIL ranked #1 in these test across all of the different weights of the oils tested. The higher the number in the viscosity index the better the protection and AMSOIL numbers were always the highest. AMSOIL 0-30 oil is the latest most advanced oil that AMSOIL offers and has the lowest wear scar of any oil made, reguardless of oil weight. According to AMSOIL its viscosity index number is 177 and although I can't find a VI number in the Mecedes standard that is required for the AMG engine, the oils that they say are approved for use in the AMG engine are LESS than 177 even though they are 40 weight oils. Another way of saying that is 0-30 oil offers better protection at operating temperature than any 40 weight oil. Furthermore coventional oils lose an average of 20% of their viscosity at operating temperature while synthectic oils lose between 4 and 10%. (I should have asked where AMSOIL 0-30 rates in this category but didn't think of it. I bet it is near the 4% though.) You can see by this that if you use a conventional 40 weight oil it has less viscosity than a 30 weight synthectic oil at operating tempurature. For the record AMSOIL makes a 5W-40 synthectic oil especially formulated for european cars but the 5 in that number means it doesn't flow as well at cold temps (start-up) as the 0-30 will and even though it is 40 weight oil it does not score as well in the four ball wear test or have as high a viscosity index number as the 0-30 oil. The 5W-40 oil is approved by Mercedes for use in the AMG motors, but according to AMSOIL the 0-30 is the best and latest oil they have and it can be run in any engine and will offer the best level of protection of any of their oils. It seems there is a lot of technical jargon that goes into the specs associated with the numbers (ie. MB 226.1, 229.31, 229.51, etc., etc.,) and what exactly they call for in an oil. AMSOIL believes that in time their new 0-30 oil will be accepted as meeting/exceeding the specs for Mercedes AMG engines. In the meantime I will follow my thinking that an oil that has the smallest wear scar is a better oil, and the newest, latest oil made by the manufacturer of the first synthectic oil is the oil I want to use. Finally I have to ask myself if it were too thin for my engine parts and wasn't lubricating them fully why would my gas milage IMPROVE after switching to it? Less friction equals better milage right? Also less friction equals less wear and less heat right? One final thought, AMSOIL will gurantee my engine as long as I use their product and since my Mercedes warranty has expired it doesn't really matter what oil Mercedes wants me to use anymore. I am convinced that AMSOIL 0-30 oil is the best oil an the market today and is unmatched with reguards to its ability to lubricate and protect my engine parts and so I am going to continue to use it, and although that is only my opinion at least you can see some of the information that my desison was based on. If someone else doesn't want to use AMSOIL 0-30 or any AMSOIL product that's ok too, I am not trying to sell AMSOIL here I just wanted people to know the benefits I have found from using this oil. I thought that was purpose of this forum anyway to share our experiences with products, etc. that we have tried. Anyway that is what I found out from the guys at AMSOIL's Tech Dept and it is what I remember hearing from them before I switched to 0-30 oil to begin with, but I wanted to make sure of my information.
