Opti-Lube XPD Formula: Diesel Fuel Additive for Improved Performance and Fuel Economy

MW: I have used Optilube XPD for over a year. I have seen a consistent 1-2 MPG increase with this product. The added lubricity is peace of mind for my fuel system. I have used other additives, and can absolutely say this one works.

Patricia Geddes: I've used this product for a few years now and really like the performance I get on my diesel vehicle, especially pulling a travel trailer. I also use an oil conditioner in conjunction with the Opti- Lube XPD, this was a recommendation of a few diesel mechanics saying it will add longer life to your diesel engine!

Melissa ChaseMelissa Chase: My husband has Been using this in our 2020 ram 3500 which is a hotshot truck on our fleet and haul 16-20k lbs regularly. There is a significant difference in the way the truck sounds, the gears shift, etc between using the opti lube and not. You can definitely tell the difference when we would run out while waiting on our next order to arrive. Been using since Sept. The price is definitely a downer, but the product is worth every penny.

2001 dodge ram: Worked great, did not need the antigel (summer driver). Order the summer formula, engine runs noticeably quieter. Thank you Torque! 2003 ram 3500, and 1999 f250.

M. Belken: We were camping in Montana and Wyoming for 6 weeks in 20-35 degree weather. Truck starts quicker and seems to run smoother w/ this. I did pick-up about 1/2 MPH when using this and towing an 8 K trailer. I am using it on mechanics suggestion to help maintain fuel pump. I have also noticed I seem to use less DEF when using, very slight difference. Engine-6.7 Ford sounds very smooth, adding 10 oz. per 40 gallons.

Zach RedmonZach Redmon: 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...

MDSWA: 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.
