TJ,

Today's gasoline with up to 10% alcohol should have already done a pretty
good job of loosening things up and sending the gunk to your fuel filter.
And anything that won't be dissolved by gas & alcohol should be left where
it's at, glued to the bottom & sides of your gas tank where it's causing no
harm.

Thanks,
Tom Hargrave
