Best lubricant
I would highly recommend this for anyone with a diesel engine. Cheaper than repair bills

This product works BEST for wear protection!
I watched a scientific comparison and this was best for wear protection!

XPD tested more effective than other additives
European diesel fuel, specified by EN 590, generally has a higher lubricity than US diesel, with a wear scar diameter specification of 460 microns, compared to the US standard of 520 microns. High pressure fuel pumps rely solely on this lubricity with vastly higher failure rates in the US being a result of this difference. XPD was shown in a recent independent test conducted by Repair Geek to bring the wear scar down to 240 microns, substantially below Eurospec and less than 4 other additive products tested.

Increase diesel lubricity
Good stuff! Great product to condition diesel fuel!

Worth the money
After finding out how much new injectors would cost, this is cheap insurance! The hand pump they included did not fit the mouth of the gallon container so it would not screw on.

Happy injectors
I've been using this product for 50K miles and my injectors, HPFP and lift pump sound happy. Truck fires faster, idles smoother and seems to struggle less overall. MPG increase is up for discussion. I've never had a water-in-fuel light, gelled fuel, algae build up etc; and I've had the truck sit for 6 months and still fired right up.I see this as cheap insurance as modern fuel systems are pricey. If this helps prolong any fuel system component, then I'll always use it. Happy and repeat customer!!

Essential for USA fuel
Diesel fuel has no spec for lubricity and cetane in the USA. Additive packages vary by brand, location, climate etc. XPD routinely wins independent testing for lubricity. Late model CDI/TDI engines with mechanical high pressure fuel pumps and brutally expensive injectors will last far longer using XPD. I’ve been using this for years in Mercedes and VW diesel engines. Improved economy, drivability and quieter operation. 30 years as an independent German marques mechanic.

XPD for my 2.8
I used this product previously in my HD GMC and had good results. Got about 1-2 MPG improvement, helped keep the problematic CP4 HPFP happy, and reduced the amount of times the truck would go into a regen. Fast forward a few years and now I have a Colorado 2.8 Diesel. I've used this product for about 9 tanks of diesel and found the results to be comparable to my HD truck. An issue I have is that the hand pump once you start nearing the end of the bottle will not suck up the remaining Opti-Lube. It also leaks periodically
