Change of oil (manufacture) for 2.5 TDi?
My 2.5 TDi is coming up for another service in a couple of thousand miles, it's been on a short service interval all it's life which is great, it's always had longlife oil but changed every 10k miles rather than 20k. It's on 145k now and I checked it today for cam wear (well what I could see through the oil filler hole with a bright torch) and they look pretty damn good from what I could see, a few very lightwear marks on the lobes but are just like light scratches really.
As its now approaching 150k I'm thinking of changing the Quantum oil for some Castrol Magnatec (same grade) reason being I always used to use Magnatec in previous cars and it is an excellent oil IMO, it really does stick well to top end components such as cams and valves etcand it's always seemed to of made the engine a lot quieter.
I just wanted to ask if it would be safe to use? I just worry about potentially clogging up the oil ways and oil breather pipes etc and causing the same issue the 1.8T's suffer with, but then it gets changed every 10k or less anyway so surely that shouldn't cause any problems should it?
