I'll talk briefly about my experience just this week with the EXP4 Diesel additive.
These products work, and work better than their direct competitors, like Slick50, STP, Techron, etc. I'm not saying this because EXP4 Additives is a sponsor of our NSX, but because it's a simple fact which we have verified through proper testing on our own.
On the way from Dallas to Daytona Beach this week, we (again) tested the performance of the diesel additive while pulling our transporter. 40 gallons of fuel will drive us for 4 hours at "redline" in 6th gear, and yields about a 250 mile range (for about 6.25 MPG).
Using the additive gives us a 300+ mile range on the same fuel load, yielding at least 7.5 MPG, or a better than 1.25 MPG increase. That increase means we consume 8 less gallons per 300 miles. The national average for diesel fuel is about $1.50 right now, but can be as high as $1.60-1.62 in California and the middle Atlantic states.
At those prices ($1.50/gallon), the 8 gallon fuel savings translates to $12 in fuel savings. For 40 gallons of fuel, we use 1/2 bottle, as recommended by AFS / EXP4. Full retail cost for 1/2 bottle is $5, so we have an instant 140% return on our money, AND we get all the other benefits of using the product, including cleaner engine internals, better lubrication and reduced emissions.
The stuff is just magic. I should also note that we believe in the products so much that we approached EXP4 to sponsor us - not the other way around. They were the first company I called, and we've built up a great relationship.
There is no BS from them, either. Their claims are real and independently verified. I've seen more techno-graphs in their offices that show their products out performing anything else on the market (by a large margin).
