I personally ignore the long life service I change the oil and filter every year using Caster edge quality oil and genuine Audi oil filter..it’s not expensive ..all 3 of our a2s max milage on one used the most 8k ..52 plate AUA, will the presence of a sump oil sensor indicate that its set up for the Longlife/AVS regime?
I have searched the internet but all I find is bickering...
That's the best oil to use, regardless of regime (annual or usage based).I bought a full filter set inc. fuel and cabin, plus NGK spark plugs for the engine because I am not convinced that the car has been properly serviced, regardless of the stamped book.
Local factors checked the reg and said "Longlife oil for your car"
5W30 full synthetic to VW504.000/507.000
Not worth pushing ... bosses wanted to string out service intervals on the mining equipment I used to work on to try and save money .... short term gain for long term pain.. especially when you are paying over 400k for an engine then the down time , loss of production etc.. .. I would just keep regular oil changes. Mine will be done at least 2 or 3 times a year . .It’s such an anecdotal subject and everyone has their opinions as has been made obvious by this thread.
I use top quality oil and am in the “9000 miles or 15 months, whichever first” camp, however it would be interesting to get an oil analysis done on my cars at that point and get an opinion as to whether it actually needs to be changed and if not, how much further could it be safely pushed before the wear protection and/or additive packs are starting to get compromised.
