    Does anyone have audio of the "self-cleaning cycle" that some are talking about? Is there a manual reference?

    Additives are done at the fuel terminal, here in the north east it's done at the boston site. The top tier companies Sunoco, Shell, ExxonMobil have their on dedicated terminals. Gulf, Cumberland, BP, use contractors to pick up and deliver their fuel (not a fleet co truck) besides the point. They get the fuel at the same place as the Top Tier companies just the fuel is different from different tanks. Cosco fuel I'd never get gas, there the lines are enough not to wait in to save a few bucks on a tank and risk low quality fuel.

    Getting low quality fuel, usually under the indicated octane rating and poor low quality conditioning adjents. OP could take a fuel sample from his tank and get an analysis.

    Isn't that the same risk anywhere then?

    I’d like to know what made the injectors rust. Bad fuel is a possibility but not the only one.

    This thread is 7 pages of people hating on or defending Costco, each with no data or at best a sample size of 1. It’s just about as pointless and idiotic as the oil change interval arguments. Get gas where you wish and change your oil when you want. Leave everybody else alone to do the same. FFS

    Quality control is done for the top 3 fuel companies at the fuel terminal prior to tanker filling. Costco may have their own inground additive tank that hits the main tanks prior to fuel delivery, no real QC of the fuel being delivered.

    My point exactly. It's likely we'll never know what made only two injectors go bad. If it was fuel, I'd think they'd all go bad. Could be just bad injectors from the factory. It happens although rarely.

    Hmmm, based on what? QC at the terminal or Costco's own QC in addition to the QC at the terminal? In Oregon, there are five gas terminals, all located in north Portland, all right next to each other. No gas trucked in, all from a pipeline.

    Thanks for that. Skimmed the thread. Maybe the fuel jockey held the additive button too long... who knows.

    No pipe line here, ours is hauled in via tanker ships. Additives done by the big companies on site.

    Or didn’t hold it long enough. Who knows? I was just offering another perspective to the idea “Costco is controlling additive quality because they love me”, when the reality is possibly “Costco is buying cheap gas with no additives on the open market and adding the mix in-house to keep costs down and profits up”.

    In my opinion, the Costco blending model is open to more uncertainty than bulk “Top Tier” fuel blended at a major depot or refinery. It also creates a scenario where the cheap base gasoline they are buying could be coming from anywhere.

    $2000 to replace injectors??? :thumbsup:

    They are super easy to replace & the injectors aren't that expensive.

    I have worked in refineries before I went upstream. In a truck rack at a Valero or Citgo refineries in Corpus Christi for example you would have trucks that were hauling for shell, chevron, Citgo, Valero, no name brands , sams club. It didn’t matter. The additives are added while loading the truck but this requires staging the additives at the truck rack. In Costco’s additive is added at the station while the truck unloads. The reason is simple economic leverage on the commodity market of gasoline. All the gas meets the same standards at the truck rack. So Costco buyers can find the best market price and pass that savings to their customers. The flexibility to buy from any terminal and the high volume keeps the pressure for lower prices. It’s a good model and I wouldn’t be surprised to see others co wider it.
    For those worried about bad gas I avoid low volume stations, and really old stations. Some metal tanks are still in service and these corrode, have water intrusi9n over time, can lose integrity below ground allowing dirt and water to enter the fuel.
    If there is a high flow of customers, and the facility is newer than 20 years old then you should feel confident that the gas is good. A bad batch of gasoline at the truck rack would impact more than one station, it would impact the entire region regardless of brand.

    He needs direct injectors not multi port injectors. Big difference.

    I dont know enough about the gas industry to comment. But even if what you say is true this guy still has 2 injectors corroded, and the only thing I know that corrodes anything is water. So where'd it come from?

    With the information provided it is not possible to come to a conclusion , I could run through a cause map and show possible causes. The OP mentioned a local chain as well as Costco, so we cannot even establish a regular fueling routine. There is also the possibility of vandalism. We do not know of any reason why someone would do this, but we all know how secure our gas caps are not. We have no photos of the “corrosion” so this could be hearsay from a mechanic trying to explain an injector not working. Ethanol could also have a cause box.

    ...from Leaking 3rd brake light..
    OP said he fueled 80% at some street joint and 20% at costco. Statistics will point away from Costco..
