Bout the same pricing and buying from a local source, WTF would you want to order it from overseas?
Anyway, just thought I'd add that I did a massive big drive, one that I do regularly and thought I would test out fuel economy and did notice I used 2.3 litres less over 120 kms, which is not much but it was a difference, mostly highway speeds, not much heavy accelerating though, but still a difference is a difference.
