I recently switch from Mobil 1 0w-40 to Kendall GT-1 Full Synthetic Euro Motor Oil 10w-30 in my AMG SLK55. I'm noticing that my engine oil is running roughly 3-4C hotter than with the mobil 1. With Mobil 1 im at 100C to 103C. Now I'm running around 103C to 106C. Does anyone know if this 3-4C difference is enough to be of concern? Should I switch back to Mobil 1?

Thanks,

Why are you switching from 0w40 to 10w30?

+1 ^^^^^^^^^^^^

I am lost on this. There is a 10w30 Euro Oil??? shrug

if its a 30w it must be LOW SAPS So dont go more than 3k miles on the oil.

You sure its a 10w30??

I work at firestone and all ive ever seen is the 5w-40 euro. Weve havent used 10w-30 in over a year. All we ever have available is 0w/5w-20 and 5w-30/5w-40 and those are all bulk except the euro. The 40 actually has euro written on the bottle.

No 10w30 Euro on Kendall's website.

AND the 5w40 Euro is 229.51 approved not 229.5 so even that is the wrong oil.

Go back to M1 0w40!!!!!

M1 0w-40
You need the correct Level of SAPS, and the stringent MB spec

Seriously man?
I mean I will sound like an a.., but AMG is not for everyone!
Go back to M1! It is factory fill in your car for a reason!

Easy on the new member, please. The guy just signed up today and posted for the the very first time and you guy jump on him like this he may not want to come back to ask any other question he may have.

For standard MB engines you may be able to use 1 grade thinner if you're out of warranty and your drive like grandma. For AMG engine you need to stick with MB 229.5 oil, M1 0W40 is on that list and easy to find anywhere. Walmart has it in 5-qt jug for $25.xx, it's hard to find any MB 229.5 oil for less than $5/qt.

No kidding! It would be my first and last question.

I have no input for your question OP. I'm not an expert and don't see what all the fuss is about personally. Welcome to BITOG!

Not quite. Modern MBs in the US should use 229.5 oils. You can't choose any 30 weight oil. Heck you can't choose some 30 and 40 weight Euro oils as they are MB229.51 as is Kendall.

And while you can choose 30 or 40 so long as it is 229.5, on an AMG you can only use xw40. No 30 weights allowed.

He was pointing out that going out of grade or spec isn't going to cause an MB engine to blow up. Going out of spec can be done if one is cautious, reasons things thoroughly, and one's driving habits justify it. If a newish Benz is used as a grocery getter or by grandma going to bingo and the oil is changed sufficiently frequently, even a GF-5 type conventional won't be the end of the world. I wouldn't recommend it, but it's far from the end of the world.

The specs are there for a reason, but we needn't act as if we're trying to run a 110 V appliance off of double the voltage. MB did include 5w-20 and all kinds of other light grades, weather permitting, not all that long ago. How thin is any oil going to get, even something a grade thinner than recommended, after a five block trip?

That being said, 10w-30 is an odd choice, even if it were an approved lube. If it were on the approval list, it would likely be one of my last choices.

So wait, he bought SLK55 AMG to drive it nice? There is Camry for that!
