Well most important that you change the oil/ filter frequently. For me a thicker synthetic 15-25/50 or a blend is good for 5 ltr thinner for twin cams.Some companies say there oil is synthetic but all it is, is filtered mineral oil with some additives. I think it was Mobil that sued Caltex for saying there oil is synthetic in U.S. Being that there is no grade to say what oil realy is, Caltex won.. Other than that the price will give you some idea.. I have also heard from an expert oil tech that 20% synthetic added to good mineral makes it 80% better...So blends I guess are o/k.. Better on seals also..Synthetic tends to dry them out, making them alittle brittle..
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
