Mobil 1 10w-40 high mileage syn 10w-40 click on this link =http://www.mobil.com/USA-English/Lubes/PDS/NAXXENPVLMOMobil_1_High_Mileage_Oil.aspx

please tell me the differences which one will keep its thickness etc.
 
the manual for my car says 5w30 to use in temps up to 62f not more so wouldnt that apply to a 5w-40 also? it says 10w30 when temps are above 62f so i wanna make sure i have the right first number for summer time.

Of course I know there is T5 0W30 and it is reasonably readily available in Canada but I am just wondering it we see a T6 0W30 in the future?

Wow, I've never heard of a 0w30 that is formulated for diesels. Is it for cold conditions only?

The data necessary to do that is not on Shell's PDS. A major parameter I use to compare oils is High-Temperature, High-Shear viscosity, and Shell doesn't put that info in their pds's anymore. The HTHS of M1 HM 10w40 is 4.06 centipoise. The old RT6 had HTHS of 4.2, so they were comparable in that respect, but since the recent reformulation, HTHS for RT6 has gone missing.

One clear advantage you can see on the data sheets is the Flash Point: RT6 is 224C, and M1 HM is 240C.

Check out page 2 of this .pdf:

ADDED: Wow, the Rotella T - SB 0w30 looks impressive for a conventional blended, for a HDEO. I wonder how it stacks against T5?



Interesting specs for a 0w30 syn blend. But look at the API rating: CH4/SJ. I see that the pds is dated 1/15/08, so this is an old oil.

Yes it's old, but not as old as most of Red Lines 5X-XX and heavier formulations despite their slapping a SM label on the bottle (which no one believes).

BTW, the current T6 formulation has a HTHS vis of 4.0cP.

Yes it is an older formulation and that is why I am thinking that it is time for an update eg update to include...at least a CJ-4 certification?

It was one reason why I chose the comparable Esso XD 0W30 (HDEO) ie it has a CJ-4 rating.

40c VIS specs are very different between 5w30 and 5w40

Also 5w30 can come in syn or dino but 5w40 typically only comes in syn

dino 40s tend to be 10w40 or 15w40

But i thought thinner weight is better on cold startup because most engine wear occurs at startup when the oil is too thick to lubricate properly?


If I understand your question, the quick answer is NO.

Here's why. The 5W refers to cold flow...and there's an old wive's tale that somehow 10W30 is "thicker" than a 5W30 but that's not true at the engine's operating temperature - when the oil is warmed up. This is explained well in the Oil 101 on the site (go back to BITOG Home and check it out...)

So, the T6 in 5W40 is thicker at operating temperature than the 10W30. It's also thinner at start-up.

Best of both worlds.

This is a case where the manual recommendation is based on old oil technology...my 1990 Toyota says about the same thing...and back in those days, it was probably true...

But not any more. Base the first number on the coldest weather the car is going to see. In a mild climate like mine, I could run a 10W30 in the winter, no problem. Try a 10W30 in a Vermont (or Canadian) winter, and you're asking for trouble...

Now, with better oil, the "right first number for summer time" is any number. I run a 0W40 in the Volvo...so the right number for summer in my car is "0".

The real question is what is the right number at operating temp? You want a 30 or a 40?

My local WM has the T6 in 5W40. That's where I got the fill for my MB.

Thanks Caterham! Where did you find that? Shell's website is a labyrinth when it comes to finding pds's. Every time I go there, I end up in a different place.
 
I spoke to shell and asked how much zinc and phosphorus is in there shell rotella t6 5w-40 and they told me it has 1200zinc 1200phosphorus i also talked to valvoline about there premium blue extreme engine oil 5w-40 and they said the same thing 1200 n 1200. So these 2 would def be better then all the mobil 1 car oils out there besides the 15w-50 which is 1200 1300.

For summertime temps, stick with the Rotella 5w40,a very stout oil .Winter in ILL is a little different,then I'd go to a 0w30 or 0w40, till then dont waste the oil.5w40 has good cold start pumpability to begin with plus it's a syn ,win!
 
Good point. I suspect all the Rotella oils, being diesel blends, have these additives and I've quit using them for that reason. My long time oil burner car didn't burn any less while using Rotella although it's thicker than all the others at the same weight. So why bother? I have little reason to use any synthetic in my engine anymore although I'm sure they cleaned it out good.
