Porsche uses Mobil 1 from the factory...that is good enough for me.
AGIP Synthetic from 96 and up/ Bosch platinum plugs and and a VW air filter.
Amsoil is what I use.


Castrol used to be good but now they don't make oil the same from batch to batch, they use more of what ever additive is the cheepest.





This question is more of a personal opinion and you will get varied answers.


just make sure it is 5w40 and it is rated API SL, CI-4, CF





this is why I use Amsoil.

Spark plug Information.


NGK Iridium are the best In my opinion.


they are one of the best spark plugs in the market.


Bosch are at the top of the list also.


what ever you do, purchase your plugs from a auto parts store and go with Original Equipment Style plugs.


meaning: Use copper where copper is speced and Platinum and double platinum where they are spec. going to another will greatly reduce your plug, plug wire, coil life, and fuel ecomony.
