I'm using M1 AFE 0w-30 right now and have no issues with it at all. However, I wouldn't hesitate to put Valvoline SynPower in my vehicle. Add to it that you're getting a great deal and it becomes a no-brainer. SynPower puts up some great UOAs, so get the Valvoline and use it with confidence. And don't worry about it not lasting, it will easily go the 5k miles you're asking of it
