My first BITOG post! I was at my VW dealer buying an oil filter and they mentioned VW has dropped Castrol and is now going to Mobil 1... is this true? I can't find anything online about it. Since I'm about and hour away from the dealer, I do my own oil changes on my â€˜17 Jetta 1.4 5sp, and use an OEM filter and have been using GC 0w40; I bought the last 4 jugs on clearance at CT a while back for Can$29, and am now down to my last one. I'm wondering, do I go to Mobil 1 0w40, which I can get at CT pretty easily, or use LM Leichtlauf 5w40 or something else German, which i can buy across the border in Maine? Will the dealer be using 5w40 M1, like they did with Castrol Edge? I think a 502.00 0w40 will always be better than a 5w40 for our climate and for the turbo. Thoughts?
