    Lol why didn’t you compare Valvoline Extreme Blue synthetic with Rotella T6

  2. Gregory Tye says:

    If you’re going to compare motor oil you should compare synthetic vs synthetic or conventional vs conventional. You are way off on the price comparison also. synthetic oil is about 3 times the price of conventional.

    1. I appreciate your response. But a lot of our readers wanted to compare them. So we did it.
