I hope I don't come off sounding like some wild-eyed counter-culture guy, 'cause that's the last pigeon hole I'd fit into, but the mere idea of having any form of "loyalty" to an oil company makes the hair on the back of my neck stand up (turns my stomach too). IMO, loyalty is a two-way street. Oil companies are businesses that, like any others, exist solely to make a profit, and they do that pretty well. Being loyal to me, or any other member here just ain't part of their game plan. Odd, but I'm just not feeling the love when I'm standing next to a gas pump these days. No, in this arena, I'm loyal to my car and my own wallet. I'll use one product until the moment another product that I judge to be a better benefit-per-cost solution appears. Today, I'm on green GC, when that's gone, whatever I think is best, and to heck with the brand.
