I have a 03 Evo should I go with 5w-30 or 10w-30 oil?

 

10w30

 

yes 10w30 it used to be called the "turbo formula"

 

Correction 'turbo formulated'

 

lol forgot the "ted" part

 

AMSOIL Product Code TSO 0W-30 oil has a more Robust additive package than ASL or ATM (5-30 or 10-30)

AMSOIL's recommendation for the Lancer Evo is TSO first and ATM second.

The car calls for 10w30, so use it.

 

Danny.... If you look at how oil is tested and rated, you will see that there is no difference at operating temps and you will get better lubrication at start-up.

I will agree on not running a heavier weight oil such as 0W-50, 10W-40, 20W-50 Etc... in a tight clearance (Stock clearances) engine as it robs HP and fuel mileage ( as if anyone worries about fuel mileage here). and cause oil starvation on cold start-up.

Cold is anything less than operating temp..

Hey guys I finally got my hands on some Amsoil oil and its 10w-40 is this still ok to run in the Evo?

 

depends where u live, do u get cold winters?

 

I live in North Carolina

 

To underscore what Oil Doc said back in April:

 

Amsoil 10w-30 is excellent too.

I sell it if anyone wants some cheaper than the online price..
