Diesel fuels have changed but the problems associated with diesel fuel equipment have not.

The diesel fuel we buy is always changing in both chemical content and quality. One constant is the propensity for diesel fuel to pick up water.  Water in diesel fuel remains the number one fuel problem year round. Now that low sulfur and ultra low sulfur fuels account for the vast majority of diesel fuels used today, water is now a bigger problem than ever before.  Water damages injectors, scores pintles, creates gum and varnish, interferes with fuel combustion and harbors microbes and fungi. Diesel Power Plus contains the most effective combination of ingredients to absorb water from fuel. The unique solution prevents damage, wear and premature fuel pump failure. Diesel Power Plus also helps improve combustion and mileage, stabilizes fuel, and prevents sludge. All of these benefits in a unique formulation which contains no harmful alcohols to attack your gaskets and seals. Our concentrated formula treats 500 gallons with only ounces.

The PLUS is a 5% Cetane Increase
What is Cetane?
Generally, diesel engines run well with a Cetane Number (CN) from 40 to 55. Fuels with a higher cetane number which have shorter ignition delays provide more time for the fuel combustion process to be completed. Hence, higher speed diesels operate more effectively with higher cetane number fuels. The national CN average is 45.

Everything I need in one bottle
(S.E. Ohio) | April 26th, 2018
I had tried other additives and was never thrilled with them. In fact, some of them made my truck smoke even more while idling. And, according to my last fuel filter, I have a little issue with algae. I tried XDP Diesel power plus because it prevents the formation of algae, and I'm very glad I did. I have an 06 5.9 Cummins and its starting faster, idling smoother than ever now and does not smoke at all while idling. The truck idles around the farm to much to get a real accurate MPG, but the overhead is showing an increase of 1-1.5 MPG. I know this sounds stupid, but one of the best things about XDP Diesel Power Plus is the bottle itself. It has the little dosage compartment built into it and you can actually pour it into you're fuel tank without needing a funnel or making a mess. Very convenient! This additive actually made a bigger difference in my loader-tractor. Pulling 12,000 pounds of hay, there was one hill it struggled to pull in 10th gear. Now with 12,000 pounds of hay it easily pulls it in 11th. Definitely getting more hours per tank also. Plan on putting XDP Diesel Power Plus in everything on the farm. Order Number 825476

Have seen a 1 MPG increase around town over the last 3 months. Have not done any highway driving but i am excited to see the increase there as well. I usually only buy Conoco/Phillips/BP fuel so not to use MidEast/Venezuelan oil. So can not say much for the fuel quality increase in that i always by good quality.

I pull a 15,000 lb 30 foot trailer 600 mi a night, 6 nights a week and have tried many additives- Howes, which my truck hated (when I stopped it I realized she ran better, smoother and the exhaust smelled better without), Lucas which keeps her running smooth, but didn't give me a performance or mileage boost, Sea-Foam which did make a noticeable difference, but is too expensive for regular use, Stanadyne,PPE, and several others, none of which impressed me...until now. I had my doubts, but about halfway through the first bottle, I began to notice that she was not only idling smoother, but gradually starting to pull stronger,run quieter and down shift less on those TN and KY grades. By the end of that bottle(which I burned through in 8 days),there was a noticeable mileage increase too, 3/10ths to 3/4 of a mpg.That may not sound like much, but remember I run 75 mph through the hills and mountains of KY and TN pulling between 9 and 15,000 lbs. I am now well into the second bottle, my truck is running better than ever, and the MPG seems to still be creeping up. Bravo XDP! I AM impressed, and am ordering 12 more bottles.
