Statistically the best product for your diesel.
This stuff is statistically better than anything else on the market. Don't take my word for it. Go look at motor oil geek's video on diesel additives. This product provides significantly more lubrication and cetane than the others. (I'm talking about you, Archoil). I have used just about everything but now I buy a case at a time direct from the manufacturer. I have noticed my pickup idles quieter and I get a small bump in MPG, maybe .5 or 1. The biggest advantage is the CP4 protection. You can either spend the money on this every tank, or spend thousands on a pump and have your truck down. This product is cheap insurance!

A good additive for diesel cars.
I've been using Opti-Lube XPD for it's lubricity benefits since January 2025. 2013 Touareg TDI diesel. Hoping my HPFH lasts forever. I have had no issues. And I just recently had to remove my DPF for other exhaust work, and the DPF is super CLEAN inside, zero soot buildup at all. Impressive.

Motor Oil Geek opinion
I watched "The Motor Oil Geek" (Lake Speed Jr. ) on YouTube. He did a test of additives for diesel fuel. This placed 1st for lubricity and one other category. So I am giving it a try.

Good Product
I use Opti-Lube to protect the injection system on my 2005 Dodge Ram 3500. The newer ultra low sulphur diesel caused several of my injectors to fail (fortunately under warranty). I also operate my truck in cold weather and the local diesel fuel sometimes has moisture issues. I tried Opti-Lube after doing a bunch of research online and it seems to do the trick. My diesel mechanic recommended a FASS lift pump with dual filters (water separator and 3 micron filter) along with a premium additive. This combination eliminated all my injector issues and seems to make the truck run a little smoother. I think I picked up a little power and mileage as well. The containers work well including the pump gallon size and the smaller bottles which are portable. Just don't get any on your hands. It has a really strong smell and is hard to wash off. Other products used include Power Service and Standyne. I like Opti Lube better and the online testing results show it provides more lubricity.

Save your CP 3 / 4 & injectors from Obama Diesel!
Best stuff out there, used TNT and PS ( white jug ) The Utah boys have outdone themselves! If you watch Lake Speeds comparison video he gave a wimpy excuse and totally ignores the “science “ he claims to follow.
