Thanks for the suggestion, but since I've never been abroad in my life I can't see myself starting now, unless I win the lottery
I'm not sure how much the local dealer charges for five litres, but presumably it would be a bit cheaper than the pro rata price of £75
The price for the litre has gone up from around £13 to £15, but they've given me different stuff this time, and this is apparently the very latest gear:
Castrol SLX Professional Powerflow, LongLife III, 5W-30
It came in this slightly ludicrous zipped plastic case, complete with VW logo, velcro strips to attach it to a suitable place, not to mention a couple of fold-out cardboard funnels, hand wipes, dipstick wipes, and plastic gloves
Of course, I'm too much of a man to use the gloves and hand wipes, and I forgot to use the funnel and so still ended up wasting a considerable amount of oil
All a bit OTT if you ask me; while the throwaway funnels are a good idea, I would prefer a lower price rather than the fancy carrying case.
