    WARNING! Heavy reading... you may go cross eyed... Have been researching more lately and found this statement:

    Still here? Stay with me...

    Then came across this interesting debate:

    FSI Engines - Audi RS4 Engine Oil-Related Deposits - Bob Is The Oil Guy

    And my conclusion is...

    That an Ester based oil (or racing oil) could possibly hold up fine for daily driving in a 2.0T
    So I have my guinea pig 2.0T ready and have filled it with... a non 502.00 spec 5w40 racing oil of my choice Motul 300V Power 5W-40 Racing lubricant for racing cars ...let's see what happens.

    Recently when my own 2.0T oil was tested in the lab, fuel contamination was found and the flash point of the oil was also not up to standard... and that oil had only been in the engine for 3k miles of a mixture of sedate/spirited urban/extra-urban driving.

    Any thoughts/opinions welcome... I guess I'm not the first person to have done this/had this idea... just interested.
