Our trucks are 20+ years old. You have a new truck, just use top tier gas.

If you throw money in a dumpster you might get the same effect as pouring snake oil in your truck. Check your owners manual or, even better, acquire the manufacturers service manuals for your truck to find the recommended maintenance / treatment for your particular engine. Chances are good that the product you are asking about is not mentioned anywhere.

Your money would be best spent on a good synthetic motor oil to keep those turbos happy and clean.

It's a concentrated detergent addictive like is blended into many gasolines, so it can't hurt. I've used Lucas power steering additive with great success, it's hardly snake oil.

With that said this subject is similar to what motor oil brand is best. Most will argue their choice is but if you use a name brand there's not much difference in quality.

A pint to all that gas is not going to be strong enough to solve any problems. Might be a good idea for prevention however.

Back in the early 80's I did some work for Texaco at it's fuel terminal in Phoenix. At that time gas additive was added by hand, the 8,000 gallon compartment took about 1 gallon of Texaco additive. The stuff must have been harsh because the driver would put on some gear to fully protect himself before he messed with the fuel additive. Point is the right additive can do more than you think.

They won't be sterile after you pour that fuel goop in them.

As mentioned already, there shouldn't be any need to add stuff to your fuel system. Buy good gas, and if you don't buy Chevron, stop by the auto parts store and get some Tercron, which is what Chevron puts in their gasoline. It is awesome stuff, breaks down carbon buildup in the combustion chembers, and cleans away any gum or varnish left behind by old fuel.
