Guy with a 3.0TDi engines - what oil are you using?
I was using Liquimoly 5W40 then changed to the VW/AUDI 507 which is the 5W30. The difference i noticed that the 5W30 got better fuel economy however i noticed that the oil heats up and cools down much quicker ( looking at temps via the lap timer) but the engine does feel louder.
I have done almost 7000Km on this oil, this is the time i like to change my oil. Thinking of going back to Liquimoly Molygen 5W40 specs of the car are:
DPF deleted - so low ash is not required
CAT Deleted
EGR Deleted
Stage 1
Thinking the 5W40 might give it a little more protection and we do live in a "hot" climate, Also modern engine have every strict tolerances
Would you go 5w30 or 5W40? I normally stick with a trusted brand oil and oil filters I use, are mainly a Bosch or Mann filter
