Valero is the company that bought Diamond Shamrock back in 2001. Headqurartered in San Antonio, major refineries in Corpus Christi and the Houston/Baytown area and elsewhere. I just did some googling, and they are actually the largest refiner (by volume) in the North America, so chances are you've already used Valero-refined fuel. Valero bought Diamond Shamrock many years before they started replacing the Shamrock name with Valero on retail outlets. For some reason, a lot of people think Valero is Venezuelan, but that's Citgo. Valero is a US company, always has been.
I've used their fuel regularly since the 80s and find it to be just fine, better than some. It certainly doesn't ping, rattle, hesitate, vapor lock, etc. any worse than Chevron, Shell, or Exxon. I don't know how its detergency would be if you used it exclusively for years, but I've never had any problems at all. That's one reason I use multiple brands, I figure switching fuel detergent packages routinely helps cover of any weakness in any one company's detergent package. One fuel that immediately and consistently causes any of my cars to run poorly is Conoco. Their real-world octane rating seems far lower than the others (according to the calibrated ear ping-o-meter applied to my '66 440) despite the same rated octane as other brands.
