Hi all, I'm soon going to give my low mileage 2006 ST3 an oil & filter change plus magnetic sump plug & washer. So many brands out there on eBay to choose from for my ST3. What's considered a good 10/w40 oil from Fuchs Silkolene, Putoline, Shell, Castrol, Motul or Motorex - etc. What's not so good? Love to hear your views...
