Following recommendations from respected members right here, I wanted to get hold of Mobil 1 V-Twin 20W50 Syn. As was not able to find it anywhere I contacted ExxonMobil in Europe. Their (very quick) response: Quote: "Mobil 1 V-Twin 20W-50 is sold in North America, but not in Europe. You can find current ExxonMobil recommendation for your engine on internet using the product selector: Mobil Norway | Car Engine Oils | Engine Oil Recommendation Generally speaking, it's Mobil 1 Racing 4T 15W-50 recommended for Harley-Davidson in Europe.
