Mobil 1 Extended Performance 0W20 vs All 0W40's

[BlueOvalFitter]

As most of you know 2015_PSD just recently sent me quite a bit of Mobil 1 Extended Performance 0w20 oil. (Thank You SO very much!

) I know, from all of my reading here and research on the interweb, that the 0W40 is thicker than the 0W20. What I would like to know is, would the 0W20 meet the set standards of an engine that states to use 0W40? In other words, would anyone here be scared to use it in a 0W40 oil spec'd engine?
Also, as most of you know, my trucks engine calls for 5W20. But, I like to run 5W30 in it every now and again. How would my engine like the the 0W20?
After reading the replies I will get I might have more Q?'s.

I would use it in your modular Ford 5W20 engine, I wouldn't use it in a (Euro?) 0W40 application, too thin, especially in LA.

BW, my engine is the conventional V6. Still, your opinion on the oil in the V6?

I wouldn't use 0w20 in an engine specifying 40-weight, but I would use it in an engine specifying 5w20.

Your truck was spec'd for 5W-20 in 2007. You can run 0W-20(no benefit to you in LA), 5W-20, 5w30 or 10w30. I doubt you would notice any real loss of mpg or power with the 30's. Going to a XW-40 oil you might notice some loss of mpg and seat of the pants power but no harm to the engine.

Even though I used Mobil 1 5w20 in the late 70s in an engine calling for 10-40 with success, there is no reason to use it today with all the various options we have.

What I don't get with your post is, you state your engine calls for 5-20. Right? Then why are you asking about 0-20 in your Ford engine? Free oil at that.

Go thicker if you want but dont go thinner.

I wouldn't use a 0w20 in a 0w40 application.

As far as EP 0w20, its' a majority PAO based oil and a good one. It seems to really keep oil consumption down in engines that burn some oil using other 20 grades.

Unless an engine has been back-spec'd by the manufacturer for a specific grade, using something thinner than the minimum viscosity spec'd, or spec'd for the ambient conditions (depending on the verbiage in the owner's manual) is inadvisable as you are going below the HTHS viscosity factored into the OEM recommendation.

Tig1, no offense towards you and I am not being sarcastic, but, you don't know the whole situation/story with me getting the 0W20. That's something between 2015_PSD and I. So, I will just leave it at that.

0w20 and 5w20 are interchangeable across the board- that's easy. Beyond that looking at the specs shows that that most Xw20s aren't really that far away from most of the Xw30s (outlier Xw30s like the old "German" Castrol being an exception), and may actually compensate by better shear stability.

But in place of a 0w40?? I wouldn't, unless I knew a lot about the specific application. For example, Yes, you would likely be totally safe with putting 0w20 in a Chrysler 6.4 SRT engine IF you knew that it was just going to be casually street-driven in moderate temperatures, not raced, not pushed to its limits, not in a hot climate. That's because the engine is *physically* so nearly identical to the 5.7 that specs 5w20 anyway, and if you reduce the loading on the 6.4's parts to 5.7 levels, then there's no materials-based reason it wouldn't be fine with the 5.7 spec lubricant. But would I use it in a BMW or AMG engine that calls for a 0w40? No way! There are other specs besides simple viscosity that come into play with some of those engines. They don't HAVE sibling engines that run on 0w20 all day every day. Nevermind the fact that BMW has a few engines that are known to have real problems with thinner grades (though most of them spec Xw60 type oils).

Sure you saw AEHaas run 0W20 in his Ferrari or Lambo. UOA was good.

The analness is out of this world. Running a 0w, or 5w30 with mmo is probably thinner than 0w20. And its done all the time. In the real world all kinds of stuff happens.

I was going to run that oil in my 02 suburban but found $2 afe instead. I think the quality of that oil trumps any viscosity concerns. If we were close I'd swap you my Mobil 1 Advanced Fuel Economy 0w30 and run it in my 02 suburban as planned.

Back in 2007-2008 I used Pennzoil Platinum 5w20 in my 2000 MB E430, as you already know the oil spec'd was/is A3/B4 and MB 293, 295, and Mobil 1 0W40 should be used.

The engine was much quieter with Pennzoil Platinum 5w20, throttle response was much better too.

MB, BMW, Audi ... spec'd oil is mostly for some drivers that drive their vehicles at or near redline on Autobahn for hours, the oil temp can be much higher than we may have with 80-90 MPH in US, the engine speed is mostly around 3000 RPM or lower. xW20 at 200-220F is thicker than Mobil 1 0W40 at 260-280F.

I use oil grade according to how the car is driven, I use a little thick than 10W30(mixing xW20 with xW40) in my S2000, because this car sees redline often, and RPM at highway speed is above 4300-4500 most of the time.

Sorry, BOF, didn't read your sig, obviously UOA would determine how long it would last in a 4.2, but EP isn't exactly bad oil. I wouldn't sweat it, but I wouldn't use it in your Ferrari either!

Agreed. Thinking depending on the engine-you would be fine....

"Your" is supposed to be spelled "you're." I.E; YOU'RE = YOU ARE.

Typical jealous jerk you are! You don't deserve to be on this board with an attitude like that. Why not do us all a favor and go play in rush hour traffic.
BTW, if you don't like what I type you don't have to read it. Just ignore me.

I get that, I just am not sure why you are asking about 0-20 in a Ford engine that calls for 5-20. Of course many here are using 0-20 in engines calling for 5-20, such as 2015 PSD. Just use the 0-20 without hesitation. You'll like it.
