Any differences between these 2 oils?

Hi all,

Besides the obvious difference in viscosity rating, was wondering if there was any other differences between these 2 oils? They seem to brag more about the performance in the 0W-40.

But to my understanding, you get better fuel economy and performance with a lower viscosity, given that the oil is not as thick.

generally as a fuel of thumb
the older the engine gets the thicker the oil needs to be, generally for protection.
racing generally thinner.
make your choice.

hi.

5w-30 are used for high performance 4 cylinders

where

0w-40 are used on turbo diesels. (common oil for mercedes users.)

cheers

I recall reading that the process in creating the synthetic oil between these 2 is different, hence a substantial price difference.

To Quote EG30 from this thread: http://www.ozhonda.com/forum/archive/index.php/t-69840.html

Hydrocracked synthetic: Castrol Edge 5w-30, Castrol Edge 25w-50
PAO: Mobil1, Shell Helix Ultra 5w-40, Castrol Edge 0w-40, Motul 8100 5w-40, Royal Purple
Ester: Motul 300V, Redline.

I assume Hydrocracked < PAO < Ester (though don't ask me what each means...)

[cupnoodle]

So you would recommend PAO as opposed to hydrocracked?

If you want (close to) the best, and are willing to pay for it, yes. However I use Edge 5w-30 myself currently because I bought 3 while on special ~$30.

Keeping in mind that Honda's FEO 10w-30 is highly regarded, and is a mineral based oil (I think, or maybe a blend?), the Edge 5w-30 does me fine.
