i had ford mondeo 2011 i used 5w20 arrived on 320k km,engine perfect,change oil every 10k km,i have for forcus 2016 same,now i have grand tourneo ecoblue which have from factory 0w20,i will change with 5w40,in italy we had in the last 2 years 40 degree,i understand is very adapted 5w40--what you think?

in europe we have some time from -30 till +40 degree celsius,so 0w20 is not adapted for this +40 temp,and more worst  for city traffic

i see many video which show short life engine with 0w20,150k km destroyed,many on GM USA,ford

I see many new info and concern about castrol 0w20 and in general any other brand 0w20 regarding short longevity and distructruction of engine,bearings, motor shaft
i have 65k km ford grand tourneo 2022 and 0w20 i think to pass on 5w30 or 40,what you know about this problems with thin oil?

you want to say ford new strategy,electronics and oil,engine design, is new global problem i understand,right?

i have for you special question--i see one case for now,John Deere can block your machine from remote,but the question is: every new car have TELEMATICS-- option-this is mean any car can be blocked from remote

you know any case of blocked car from remote by ,maybe dealer,insurance,police,etc???

You may have a misunderstanding of what oil viscosity means and how it relates to your engine. Modern engines use hydraulically-activated parts such as cam phasers, are built to tight tolerances, and are actually designed to work with specific oils. Therefore, the oil recommended by the manufacturer should be used unless maybe you're running a performance-modified car on the race track.

There are youtube videos explaining oil viscosity such as:

@gabi1g What are you talking about? The issue here is not 0w20 oil, it's the "Ford". Nothing else needs to be said.

The information you are seeing is incorrect: Here's why  

 


@hixster I also remember hearing it mentioned somewhere that in order for 0w oil to span such a wide temperature/viscosity range , they have to add serious modifiers. (mainly for such a thin oil to retain film strength at higher temps) And that those additives don't last as long as the oil itself. Not that it means it's bad oil if changed regularly, but it's something to bear in mind. I'll see if I can recall the source ...

finally,is better to replace quicly 0w20 with 5w40 for temp +35 /40 degree in the summer,even diesel consumption is more big,but increase longevity for all mechanical parts
