P040416Z Diesel Extreme Clean and Boost - 16 fl. oz.

Super fast postage, used it only once so far but seems to do as it describes

I usually don't believe in this stuff much, find it's mostly a waste of money. Had an old diesel sit for 9 years, ran rough as heck obviously on its old stale diesel fuel. Tossed half a bottle of this in, and filled the last half of the tank with fresh diesel and it runs better than when I parked it. Definitely buying a few more of this stuff.

I don’t know, might be a just another way to put more money into your gas tank with no to little result. Can’t say. But might work.

Seemed to work well reducing smoke and increased performance but took some time until results were obvious

works as advertised
