Thanks for the info guys... I actually lucked out and after an hour of searching I came across a europarts website and was able to acquire 9 liters of Castrol Edge 10W60 for 65 GBP which is around $95 delivered to my door in the UK with a 30% coupon. I don't think I have seen anyone else get it any cheaper than that overseas.
Hopefully this will be the only service I will have to pay for while stationed in the UK. I should be back on American soil in 2 yrs time, and I don't plan on driving the car much during the winter months.
All I have to do now is get my hands on some rear outer tail lights (amber indicators) and the interior light switch that has a rear fog light button to get the car within European standards. Anyone have contacts or part numbers for these? I would rather get these now with a VAT form while TDY at Spang, so they are ready to install when I return.
