Praise for Seafoam

[blown motor]

My daily driver is a 15 Challenger SXT with about 125,000 km/75,000 miles. I travel back and forth to the US regularly. I usually get my mileage a little under 8 litres/100km. This year my gas mileage has sucked. So I dumped a half a can of Seafoam in the gas tank and filled it up. I just got home and on this trip I did 7.7 litres/100 km! It hasn't been under 8.2 all spring and summer. So that's 35.9 mpg vs 33.9 mpg. A full 2 mpg better. Call me a believer. Now I'm wondering how often I should put it in.

From their website:

For cars and trucks driven regularly: add to fuel every 3,000 miles.

I'll keep this in mind when my T/A starts getting worse mileage. I wonder, does anyone use it in our carbureted Ebodies and not for storage but for driving around.

Seafoam is a great product.  When I pull the (vintage carbureted) scooters out for the summer, I usually must use this product for them to run well.  After a tank or two of this stuff, they are fine for the season.  I love this product.

I use it, but never saw any mileage improvements. I just figure it's a cleaner.

If it works it works. I've used their transmission additive w good results. I cant look at mileage w a 426

With a big HEMI, I thought it was always calculated at gallons per mile.
