Ford Owners Manual - Top Tier Gasoline

Agree with Costco gas in CA, ran in my GT500 when I had to daily it in CA and it was good fuel, never had an issue. At least in AZ, Costco gas seems to be a different story. Ive been told of a number of drivability related issue with Costco gasoline come through the shop from my Diag Specialist. Official shop advice to customers is to avoid Costco gas. Shell, Chevron, Valero and surprisingly Quik Trip fuel are all GTG here in Phoenix.
Im guessing cosco gets there fuel source from different places depending on where they are located
Thanks for sharing. I’ve seen the logo Top Tier on some pumps and always wondered if it was a gimmick.
Different fuel standards here is another reason. California has much stricter requirements for clean burning fuel and higher penalties for non compliance. Free states dont have as stringent a fuel spec and thus, less liability. Costco sells SOOOOO much fuel because of their substantially lower price (for CA), but they still need to meet CA spec.

Gas companies (Shell, Exxon, Mobil, etc.) pay to have their fuels certified as "Top Tier". Basically it's tested to ensure it has enough detergents & additives in it. Good Consumer Reports article about it can be found here: Study Shows Top Tier Gasoline Worth the Extra Price

Just because you fill up at an Exxon station doesn’t mean you are getting only Exxon fuel. Think about it Exxon doesn’t have facilities all over the USA to refill all there stations. You are getting anywhere from 10% to 80% named fuel at that station depending on the type of station. You are paying for the right to use your Exxon credit card not Exxon fuel.
Dealer stations have to have a higher percentage of named fuel at there location. They have the words “dealer station” above the entrance or words to that effect.
Now you do get what you pay for so your Exxon station may be paying more for higher quality fuel versus buying on the spot market which can be cheaper at times and more than likely lower quality fuel.

Good to know that info.
I also remember (probably 20+ years ago) reading in one of our previous Fords's manuals a section stating something like, "If a tanker truck is unloading fuel at the station you are going to stop at, keep driving, do not purchase fuel there." I always thought it had to do with the amount of sediment the incoming fuel was stirring up inside the underground fuel tank. So, I've always stayed away from those stations...
And i believe that to be true. The filters should catch it before it ever reaches your fuell tank but anything is possible
Many, many, many years ago this was true. You did not want to fill up at ANY station where the tanker truck was in the process of offloading bulk fuel into the underground tanks. As stated this stirred up the sediment in the fuel tanks and was subsequently sucked up by the pumps currently dispensing fuel. This is no longer the case these days because most gas pumps have at least 2, and some even have 3 filters between the underground tank and the fuel nozzle and we're not even counting the fuel filter built into your vehicle's fuel system.
This is no longer an issue anymore.

Very true. I have worked at a big box gas station and we would get drops from all kind of different vendors. It's all piped in from the same place, the differences are going to be what additives each station is putting in their own tanks.

I would sit back in a lawn chair and watch that.

it's all the same shit. The ONLY difference is the additive. Which you can buy at walmart, and use once a month (techron or lucas). So fire away, use the cheapest station you can find in your area. Every single station (name brand) is going to use some sort of additive.
