I see that a FCA has an addendum for 2.0T recommended oils referencing MS13340, what specifically does this mean ?
Thanks

It means other oil companies haven’t PAID FCA to endorse them YET for the ability to put that rating on their bottle. Don’t get me wrong Pennzoil, Quaker State, and Shell are all fine now BTW they are all the same sine they have all been owned by Royal Dutch Shell since approximately 2012.

Spec= API SN Plus rating
The oils listed are approved API licensed to meet the spec.
Marketers of oils can state that their oil meets or exceeds SN Plus requirements but cannot use the API seal until licensed by API.

The Spec is meant to prevent low speed pre ignition (LSPI) that is more common in turbo charged engines due to higher operating temps than non turbo charged engines.

Direct injection engines also have a higher risk of oil dilution due to fuel cylinder wall wash down diluting the oil.
Variable Valve Timing engines (VVT) require specific viscosity to work as designed and oil dilution can be a problem for engines with VVT.

GF-5 spec is basically using additives to allow for the lowest possible viscosity to improve economy and meet lowest emissions and deposits while maintaining wear protection.

I use AMSOIL SN for turbocharged engines. It appears they market as exceeding the spec and have licensing. (XL, OE, and signature series)

AMSOIL also recommends using the "severe duty" oil change recommended interval vice the "normal duty" due to turbo charged engines having higher temps and is harder on your oil.

So if I read this correctly, FCA says it’s ok to use any syn oil that is API SN PLUS certified. Good deal. I’ve been running Amsoil in my turbo cars for a while. I changed the JL over to it at 3k.

FCA does the same political shit with MS6395. Amsoil Signature would laugh off either of FCA's standards. I run Mobil 1 and it would do the same. Amsoil won't pay it and FCA won't allow Mobil 1 to have it. (They will, however, allow Mobil Supersyn, because Shell doesn't see it as a premium oil, and therefore doesn't view it as competitive to Pennzoil Platinum.)

I'm not bashing Pennzoil as a product. It is outstanding oil. It just isn't my favorite.
