Hello,
I been meaning to ask about what oil would actually be better between these grades of oil.
In Australia - We have the Gold bottle 0w40 mobil1 which is their flagship product.
Then we have a 5w30 Mobil 1 super 2000 (might of been 3000, cant remember now)....
I rang up Mobil tech down here and either is fine for my engine.
Now...
From what I been able to dig up... a 0w40 weight will have more polymers in it than say a 5w30 or even a 10w40. To create more spread between cold and watm temp more polymers are needed.
From what I been able to read more polymers makes the oil protect less.
So technically speaking the flag ship product 0w40 isnt as good as a 5w30 or a 10w40 as it wont protect as well due to more polymers to create such a wide viscosity rage between 0w and 40.
Whats the truth to this?
Where I live the temperature will never be below 5°C when i turn the car on so even a 15w would be more than fine...
On the other side of the argument people say a 0w (anything) will be better than a 5w anything etc simply because oil will get to entire engine sooner than a thicker w start even in those temps im talking about which are not that cold to other places where temps get below 0. Also since more technology is being invested into the 0w40 type oils above the others then even if they have more polymers or ehatever the oil itself is better and will therefor protect better.
So yeh just trying to work out whats actually gonna protect the best out of those and whats actual vs logical assumptions that could be way off.
