I did a Biobor shock on my tank, last week, and the filters started getting full of crud immediatly. Had to change the primary 4 times in 400 miles.

Put in a dose of Startron early this morning, and the car actually runs better already! Less crap in the filter this evening than the last few days.

I drive the same distance almost every day (80 miles round trip), and I could feel the car starving out the last few miles, each evening. After the Startron early this morning, the car ran great all the way down and back!

I am sold, Startron works....................
