dpando1 AH I forgot about DI...which is insane cause that should have been obvious. But it would benefit the injectors that are directly in the cylinder?

thanks for everything btw
Anything you put in the gas tank won't ever clean the intake valves unless you have fuel and air leaking out of the cylinder back into the manifold with these cars.

Direct fuel injection means there is no air/fuel mixture inside the intake manifold, only air and a bit of exhaust gasses that are recirculated pass through the intake into the cylinder. Fuel is injected directly into the cylinder itself at high pressure.

This was one of the key enablers for the 12:1 compression ratio to run on 87 octane fuel without the increased risk of pre-ignition or spark knock in a SI (spark ignition) engine.

mikebontoft So was I lol. I've used it before but I was looking for something specific. I'm gonna grab some now actually since my injectors could use it

What is probably happening is as mentioned. There's crap buildup at the bottom of your tank. Why it happens to you and not the other guy depends purely on the contaminants within the fuel at each station.
Thanks...really yeah its tough and i feel you on that fuel economy! Had a 1991 f-150 and oh man i don't know what the outlook on gasoline was back than but from that freakin truck they must have been swimming in it.

so seafoam? Ill check that out. it goes directly into the fuel tank?

edit: might I add, however, the benefit of keeping it at least half full vs a nice several-hundred-dollar bill to replace the pump?

that's what Im pretty much forced to do all the time...what's wierd though is once I pop in like 10 bucks of fuel it stops....

I thought it was some cool feature that decreased fuel consumption when the tank was low lol

I totally agree with you on that....and I should but is it possible for me to do so, not really. Unfortunately its very expensive to go to school nowadays. and due to how little classes are offered at any one school in my area I need I am driving everywhere. So i am forced to stretch my tank frequently...

thanks for that info though. So is that what is causing the sluggishness at around lets say 50-60 miles of tank left?
