I want to know if amsoil is ok to put in a Mercedes-Benz. Or should i keep using xado engine oil.

 

Not sure what Xado oil is exactly, but it doesn't sound familiar and I doubt it's 229.51 or 229.52 spec stuff.

You want to use MB spec oil, warranty or not.

As far as Amsoil, they have a 5w30 European formula that claims to "meet or exceed" MB's specs above. The only actual license/certification/approval they list is the VW 504/507 spec, which is a pretty tough spec to achieve and is used in the common-rail TDIs (and gassers, but that's beside the point).

Do I recommend it? No, simply because it's $15/quart and I can get much better-priced oil that is actually approved by MB.

Will it hurt your Bluetec? No.

 

Xado oil is used in motorsports. Here is the site http://xado.com/global/
xado has very good oils and engine additives that makes the engine purr more smoothly. Xado has been proved that it protects the engine for a very long time. Unlike the oem oil that Mercedes gives out.

 

IMO, if a company makes great oils it doesn't need to also make oil additives... But to each his own. Honestly had never heard of Xado in motorsports either. You must be in the Ukraine?

Again, MB spec approval is more important than brand or viscosity grade.

On the MB Bevo site, you'll find the following listed:
XADO ATOMIC Oil 5W-30 504/507
XADO ATOMIC OIL 5W-30 SN

These are both MB spec 229.51 approved. I would use whatever oil is most easily available and best priced that meets the spec I need. In the case of the OM651 engine, that's either 229.51 or 229.52 oil.

 

I live in korea and oil here is priced double or even more then what the prices are in the states. For example if it would be like 200 to 500 bucks in the states for and oil change. In korea its tripled. And i have tested the oils here in korea and the oem oils are bought from hyundai. Some how Mercedes Benz korea has partnered up with Hyundai so i have my doubts about oil and engine care with these koreans

 

I use 'Other'. Mobil 1 ESP Formula M 5w40 (meets both MB diesel specs).

 

Moi, j'utilise Pennzoil euro LX vendu chez Canadian tire au prix de 33$ pour 5 litres en spécial. Il est approuvé 229,52 et 229,51

 

Great suggestion. I'm switching to Pennzoil euro 5w30 since Mobil 1 has gone up from around $40 two years ago for six quarts to almost $80. Can get Pennzoil Euro from Walmart for US$27 for a five quart bottle. 229.51.

 

Also note that M1 ESP 5w30 carries the 229.51 approval, and if you want a "thicker" oil Havoline ProDS Euro 5w40 is also 229.51 approved.

There are many 229.51 or 229.52 oils readily available, including PP Euro L mentioned above (which is a great oil for the price, btw). There's really no reason NOT to use approved spec oil, particularly if your Bluetec has gotten the AEM work done and is now on extended MB warranty. I wouldn't want to risk coverage because I used an oil not approved by MB.

YMMV

 

Thanks. I've had the AEM work done and I've used 229.51 oils from the beginning (M1 ESP). But I don't see any reason to use an expensive oil if more reasonably priced oils are 229.51 approved. I'll check out PP Euro L. I call myself frugal; my wife calls me cheap!

 

I don't want to pick a fight, but all the info I've seen indicates the 5W-40 offering does not meet either 229.51 or 229.52

I'm with slmskrs, The Pennzoil Euro L is a 229.51 oil at a very attractive price.

[edit] I just realized this is not a Diesel only forum. Best separate the two (gas and Diesel) as the requirements are vastly different.
[edit][edit] On second thought, it is a Diesel oil poll, so I emphasize my first point...

 

I'm also using Penzoil euro L . For the price, hard to beat.

 

I use Mobil1 ESP exclusively.
