Isnt the change interval 10,000km or 1 year which ever comes first? According to the manual at least.
so, a touchy subject for sure with lots of arguments and debates
long story short, yes all 3 are correct, 10,000 miles or 10,000 Km or 1 year
WHY? because the manual says so.
NOT!!!!!
Because marketing BS and oil tycoon whatamahoozits and a bunch of generalizations by VW to say, we expect this to do this for this long under normal driving habits and conditions. AKA a good guideline for right down the middle of the road maintenance
the reality is that all the older type TDI's can easily reach 13k to 15K miles on a synthetic oil with it still being within spec on its lubricity and viscosity range. that goes for most diesels
Is it unsafe to keep oil around in your car regardless of miles based solely on years? no that's complete BS. its been proven that age does not make any difference. heat does!
IMO however, change your oil as frequent as you love the car.
I spent the $ on 6 oil analysis' and came to the conclusion that at 16K on mobile one i was starting to fall out of spec. i changed the oil at 13,500 at that point.
some of the new oils we have out there now really will perform properly for up to 20K. the reason we stop at 20K is that the oil filter is spent.
