I just picked up 8 quarts of the Valvoline DEX VI from my local NAPA. It was on sale for $6.50/qt. Also grabbed 2 quarts of Valvoline SynPower 75w-90 Differential Fluid which were definitely not on sale @ $13.90/qt. I have yet to order the filter kit which I've found @ Pelican Parts for $28.xx. For the transfer case fluid I think I'll stick with the BMW stuff which Pelican also has for $47.50 for the litre. BavAuto has it cheaper but with shipping it's only $2 more @ Pelican.
