In my opinion the best diesel engine additive
Although expensive I feel it’s the best bang for your buck. I can works perfectly for my RV fuel tank. I’ve noticed a smoother running engine and trust it with my rig. Recommend

Quiet idle and smooth starts on the old 7.3
Tried another brand of fuel treatment to help add some lubrication to the injectors. I could never tell the difference to be honest, and the bottle it came with was terrible. After some further research I found the laboratory tests comparing this product to everything from competitors to ATF and 2-cycle oil. After giving it a try, I am very pleased. My 97 7.3 with 140k miles ran noticeably quieter right away. Been running it for 5k miles and will be buying a larger refill for my next round.

Need more time to evaluate
A bit premature to rate since I’ve only added it to one fill up. Have used Hotshots Secret EDT in every tank for the last 9 months and I even bought a gallon jug of it which I just cracked last month. I’m just experimenting with the XPD to see if it justifies the price, which works out to be approximately 3.5 times that of the Hotshots Secret EDT. I watched a YouTube video where that tested a number of diesel additives and the XPD came out on top…I’ll just have to see for myself… maybe an update to this review in the future
