Re: Anyone have problem with Costco gas?
No problems with Costco gas here in Upstate SC. I haven't used any premium grade as I usually fill my truck or 'pocket rocket' there with the regular grade. But I do try to stay away from any station (cut rate or premium brand) if I see the fuel delivery truck on the lot. I'm convinced that pouring that new gas into the storage tanks just stirs up any deposits and/or condensation. All stations are suppose to have filtering on their delivery systems. But filtering out crud or deposits is a lot easier than removing condensate or moisture. And I doubt that the cut rates (and maybe the premium) stations have fuel /water separators on site to address any moisture acumulation. So I avoid filling up when they are taking deliveries.
And I do use HEET during the winter season, especially if any of my cars sit for an extended period. Otherwise, a can of fuel system cleaner every 4 months or so is routine for me in all my cars.
As neoprobity & xfirepop both stated above, the gas all comes out of the same pipe! And remember, once you get 4 ft below ground level, the earth's temperature is fairly constant around 45-50 deg F. That's why tanks are typically placed underground. Surrounding soil acts as an insulator, which reduces the likelihood of condensation accumulating due to large temerature swings. So it's only a matter of preference on which additive package you like best or your perception of how 'clean' any local station operates their tank system.
