I'm just getting tired of scouting around for different oils and want to settle with just one for all my vehicles. The weight would be 5w-30 year round, the 0w-30 Castrol Syntec is a hit and miss when looking for it.
So if it were up to you would it be Valvoline Synpower or Castrol Syntec (American Version)?
