aren't our tanks poly?

 

This isn't a tank off an HHR, this is out of a F350 stepvan body.

 

Chevron's is Techron (or maybe Techron II, now). I can't vouch for it.

I used to use the Lucas Fuel treatment, but it would literally thin out the motor oil and I would blow a bunch out the PCV on the Saabaru.

As a result, I tended to do it just before changing the oil and only for events. I had to really watch my oil level. I never had fuel system issues in over 140K, but I can't honestly say it helped with either power or MPG.

As an aside, I can't stop thinking about Steve Earle's song, "Snake Oil" now...

 

understood but who hasn't replaced a gas tank in a ford truck from the early to mid 90s that had rust in it

 

Except this was not rust from the tank, but crap from the underground tanks. This was a 2 year old 2004 model (pic from 06). Was even funnier, this was from a Texaco station which is listed as "top tier"......

 

Seafoam and Berrymans B12 are both good gas cleaners...

 

ok fair enough...so what fuel additive gets rid of that?

 

Crap like this will have to be manually cleaned out. It will clog the sock on a fuel pump fast. But some can still get into the lines and clog injectors. That's why I use the seafoam about once a year. You never know what's in the tank at the pumps.

 

wht about gumout i think the name is right

 

What are you talking about?
