Hi guys

hoping you can help me out. my audi 2.0 tdi 150bhp is coming up for a service/oil change and would like to know which oil is best to use for such a high mileage car. brand/spec/5w-30 or 40? Thanks for your help guys

Hello Kevin,

Thanks for joining, and welcome.

Re. engine oil:- 

I can only go by personal experience with our 173k humble 1.6 petrol - still using the recommended 5w/30 and have always used Quantum Longlife since it came out of Audi dealer servicing. 
As I understand it, Quantum ( believed to be a subsidiary of Castrol) has been/still is? VAG recommended brand.

I don’t see any reason to change brands and certainly not grade. With ours, the oil gets changed annually ( annual mileage now c7K) together with a Bosch, Mann, Hengst oil filter ( I won’t use filters from a certain three letter factors). Air filter and pollen filter gets changed every other year - that’s my routine. 
Quantum Longlife 5w/30 is available from a number of EBay sellers.

Hope this helps.

Kind regards,

Gareth.

Just had a look on EBay for you - Quantum 5w/30 Longlife 3 from  CE Automotive is £35.75. 
Think I got my last lot from them, but no connection. 
Kind regards,

Gareth. 

Was any of the above any good to you Kevin, and are you going with this or not?
