Is there a difference between STP fuel injector treatment or (any other fuel treatment that you add to gas) and Shell v-tech @ $.30/gal more? Both claim to clean injectors and fuel system. And both cost about the same.

 

Fuel injector cleaner is meant to obviously CLEAN out your injector (uses concentrated polymers that break down the build-up and flush it out).

Shell V-Power gasoline is just gasoline. They give it a fancy name and say they've done this and that to make it do whatever... It's 93 octane premium fuel that does nothing special (or I don't believe the crap they say it does).

 

The Shell super-duper gas (and their advertising) is designed to do a better job at cleaning out your wallet as opposed to your injectors.

 

By federal law all pump gasoline must have a certain amount of additives to keep injectors and valves clean, no matter what the octane rating. All other claims are mostly BS. If the injector are clogged different gas won't fix them, get some injector cleaner instead.

 

Sea foam

 

...Sea foam run.

 

seafoam is awesome!!!!! make your car look like a white smoke blowing diesel

 

And that is supposed to make it run better? lol

 

The best thing you can do for your fuel injectors (and whole fuel system, while you're at it) is to find a gas station that doesn't have ethanol in their gas. Ethanol is a more stable substance than gasoline, which means it doesn't ignite exactly the same way, which means that the combination of gas and ethanol igniting together leaves more residue than either one alone would leave. For cars like ours that were made before ethanol was standard in gasoline, it's best to run pure gasoline. If you want an additive to clean your injectors, get SeaFoam as suggested above. Don't add it every time you fill up, though.
