What about Valvoline VR1?

I think that Valvoline VR1 oil is a good substitute if a guy wanted to save a few bucks instead of the Mobil One. I've got friends that use it and have never heard anything negative about it. It's dinosauer-based and gets by the EPA by not having the starburst-grading system on the back of the bottle. So it's not really certified for street-use you can say. You just need to trust Valvoline's great reputation that's it's a quality product, which it is. In, fact, it's what I use for break-in before the Mobil One.
