Audi 'Long Life' service Oil

Featured Replies

Just had my Q3 serviced. The documentation indicates that Castrol GTX 5w-30 has been used for the replacement engine oil. The service interval on my car is set for 'Audi Long Life Servicing'. Is GTX a suitable oil for this longer service period?

Hello Anthony, 

The all important question here is - who serviced the car for you ? 

Audi were/are still recommending the use of Quantum Longlife 3 where vehicles are serviced on the Longlife schedule.

GTX? As a matter of interest, what brand of oil filter ( and air and pollen filter) has been used? 

Kind regards,

Gareth.
