hi, trying to find the previous owner or at least figure out my new 2013 SHO

I run RP HPS as well. I want my oil to have an add pack that protects turbo bearings more than the epa restrained oils that meet warranty requirements.

Great link!

Excise what you choose to, but read ALL THE REST OF what was/is published in the link.
I did, and then I read some more...

"Improved compatibility with fuels containing ethanol
Patented additive technology prevents the white sludge and lubrication starvation that can occur with 20% or higher ethanol fuel"

As a bonus, it won't cause any issue with oem API certification.

Damn, no 0-30.

Amsoil SSO datasheet
To further muddy the waters ...
 
O weight flows better in cold temps and provides faster startup protection.

The first number is the viscosity when cold....

Second number is viscosity at operating temp.

Thx for the insight. Looks like I'll try the 0w30 in the winter months.

OK thank you for that. Never knew that.
