Just an FYI, the price of regular gas at the La Plata Wawa is $ 2.87.

That's awesome !! I always get gas at Wawa. However, someone just told me this morning that it's bad for my truck? He told me that Wawa gas contains more of something or other chemical that is bad for your engine?
Is this true? I have a Toyota and I plan on keeping it till at least 200k and don't want it to die on me
I've never heard that, but i was telling someone the other day that my car seems to act odd when I use Mobile gas. I always use WaWa, have been for years now, never had or heard of anything bad about wawa gas
All gas is the same until it gets to its final destination (ie: Wawa, Sheetz, Shell, etc.). Those companies can and do add things to it but nothing that is going to "harm" your vehicle.That's awesome !! I always get gas at Wawa.

"So, this is my life and what I do. Im not prefacing saying my words are chisled in stone...but they should be.
All petroleum products in a given market are 99% the same fuel. It comes from the same refineries, delivered through the same pipeline etc. One it reaches a ditribution Terminal, additives are mixed into the gas before it is sent to the stations. These additive are performance improves and detergents to keep fuel and combustion systems clean. This is pracitically the same regardless of the company you buy gas from.
The difference is in the additives. The US EPA assigns an LOC "lowest allowable concentration" of additives for fuel. High volume marketing companies like WAWA or Sheets but a bunch of gas tat simply meets the governments standards. Branded stations, (BP, Exxon, SHell, branded with the name of a true oil company) are far more vested in turning out a highest quality product. The treat rates for their products is often 200 to 400% of LOC. More additive means more power, cleaner engine and better gas mileage.

What she said....
And I may be showing my age here, but does anyone else remember back when Shell wasn't a premium brand, it was actually the cheapo fuel station?
I may not be a 20 year master mechanic (though I doubt that Yahoo poster was either, in truth), but I do know a bit about engines and fuel. The additives come in three types (four, if you count Ethanol as an additive).
Detergents (and corrosion inhibitors): These only provide "performance" if you have considerable build-up of contaminants in your fuel system and if used over time. That said, they tend to lower the energy density of the fuel, so you lose power today to potentially save power tomorrow. Let's call it a wash.
Octane boosters: The effect that these have on the fuel is literally labeled, and using a higher octane fuel than is necessary to prevent pre-detonation (pinging) doesn't provide additional benefit.
Lubricants: Like detergents, only provides a benefit when needed. Adding more lubricant than the minimum wont make your pistons extra slippery, it can actually gum them up (like adding more grease to a bearing than is necessary).
And as for Ethanol, the only benefit that provides is keeping farmers employed. It is less energy dense than regular gas and has corrosive properties that are harmful to rubber/plastic components.
Bottom line, I would feel much better about buying gas from a 3 year old WaWa station than a 20 year old Shell, as the biggest likely issue with the fuel would be contaminants that come from the old tanks/pumps.

I worry more about the tanks its stored in than what they put into it. The old gas station that was in front of Queen Anne apartments used to have about an 80/20 gas water mix.All gas is the same until it gets to its final destination (ie: Wawa, Sheetz, Shell, etc.). Those companies can and do add things to it but nothing that is going to "harm" your vehicle.
You are very right... But, those additives are what make fuels different. Really doesn't matter if you use them or like them but they are different. That is the difference between WaWa and Shell. With Wawa you do not know what you are getting, With Shell you do.. Cars are like people, Different people run different on different foods and some cars run different on different fuels....doesn't make one or the other better, Just different..
