It's about time for the next service and I was wondering if there is any real benefit to using Castrol GTD Magnatec instead of the Castrol GTD I used last time around. I know what it is supposed to do and it all sounds very nice, but does it actually make any difference and is it worth the extra money? If anyone has any other recommendations I would be interested to know.
It's for an N reg Peugeot 306 DTurbo if it makes any difference and I'm doing mostly short journeys from cold at the moment.
Thanks,
Shaun
