Opti-Lube XPD Formula

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!

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

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.

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.Look up the hotshotter with 970,000 miles on his Ford 6.7…2004 Dodge 3500 HD SRW250k5.9 / 3.73NV5600Banks Goodies5” Turbo back exhaustAnderson Hitch33’ 5th wheel

I will start by saying i have tried NEARLY EVERY different brand of Diesel Fuel additive on the market, from performance blends to Lubrication blends. They all promised the moon, and very few of them did anything at all from my experiences. Opti-lube was the last one for me to try as i couldn't get it locally, so of course i tried all the brands i could find locally. I wish i would of STARTED with Opti-lube products first! This stuff is amazing, im not one to follow hype around products i like to see proof with my own eyes before i make up my mind. I had always seen on Facebook Diesel pages that the best stuff was Opti-lube, but it always turned out it was a Vendor saying those statements. Well after trying FOUR different blends from Opti-lube im here to tell you that if your having a problem getting quality fuel in your area this will fix all of your issues! Here in Alabama good diesel fuel is not around at all, you take what you can get. Well now with me using Opti-lube i have increased my MPG by roughly 15 miles to the tank, my throttle response has greatly improved, it starts up cold without any second thought, and it over all idles and drives better and smoother. I will continue to order Opti-lube for as long as i continue to own my truck! I'm currently mixing The XL, XPD, and Boost blends together in every tank and my motor couldn't be happier and all of my injectors are within + or - 1 while at park and idling.

Best review for active ingredients.

Good diesel fuel additive.keeps injectors and pump lubricated.

On my first fill up with this additive and so far it’s been great. it’s been a better and smoothie starters on my diesel truck
