Neo Brothers Saab Fully Synthetic Engine Oil 5W-30 93165212 Having just bought a Saab I was pleased to see that the Saab (GM) oil also meets VAG specification 505.01 suitable for my A2 and costs only £19 for 5L. This oil also meets 229.51. Postage is £9 though. But if you buy 10L it works out as £5/L....not too bad and cheaper than Opie Oils. I imagine this is more than Costco, but remember not everyone has a membership card. Hope the above is of use to some members. edit: Ebay has 2x5L for £45 inc P&P.
