When I had my '04, I always used Mobil 1 0-40. Now, on my '08, the filler cap states that Mobil 1 10-40 should be used.

Of course, I didn't read the cap until after I'd done an oil change with 0-40.

Any explanations?

Not sure, but I know they changed it to 5w40 awhile back guess it's changed to 10w40 now. I'm sure you'll be safe putting in 0w40.

 

You are in Alabama. Stay away from Canada for a few months and you will be fine.

The low viscosity is for cold weather starting.

they originally just forgot to put the "1" on there.....lol.....

 

What another Canada crack and from YOU Franc! What's this forum become?

 

yeah Franc, you forgot to say.... eh!

 

Don, the wife just left for work in her '08 so I can't look at the cap right now, but......pg. 267 of the '08 owner's manual still says ..."such as Mobil 1 SAE 0W-40."

 

Maybe that cap fits more than one style of car ??

 

Mobil1 0w-40 claims European spec. 5w- and 10w- do not. Since mine are summer drivers (and low viscosity for ultra cold weather is not an issue), I use 5w-40 which I can often buy in 5 qt jugs at Wally world for $24. On the other hand, my A6 2.7T gets 0w- year round.

 

Does anyone else have trouble finding 0W-40? I live in the Tundra of Desolation yet I can never find 0W-40. The only Mobil 1 I can find that weight is the Turbo Diesel, but I know that has a really hi zinc content for tappet motors (Audi).

 

Obviously you are only referring to Mobil's 5W-40 products.
Their 5W-40 motor oil is called Turbo Diesel Truck.

I know you aren't referring to other companies 5W products.
If you are, you're massively incorrect in your statement, as there are quite a few other oils that carry European brand approvals that come in 5W-30 and 5W-40 flavors.

BC.

 

It's a PITA, I stopped using it.. I use any oil on the MB spec list the store has.. I just bring the 2 approved lists and find one that comes in a jug lol.

 

No kidding! F-it, I'm going to do the same thing.

Hey, what are you Steven Hawking's boyfriend or something?

 

We were once lovers, a long time ago.

 

You too?..........sadly he never mentioned this!

 

OK, I have an '08 and I just went and checked my cap - it doesn't list an oil spec on it at all, only something along the lines of oil level must not exceed max or engine damage may occur - in both english and german...

 

What oil cap????? Yours must have come fully loaded !!!!

 

There is usually a sticker on the radiator crossmember, on the drivers side, that says something like... Mobil 1, 0w-40w synthetic oil only

 

Try advance auto online -- they will mail it to you for free if you spend so much . I can't remember if it is 75 or 100 dollars. Also maybe try pep boys and autozone online. I have had it mailed from Advance Auto though when they were having a sale.

 

OK thanks, I'll check that out.
