OPTIMAL LUBRICATION
Your truck has been there for you every minute and every mile, which is why it’s important to keep it in pristine condition. At Opti-Lube, our goal is to keep your engine operating at its best. Our fuel additive helps to increase the lubricity properties of ultra-low-sulfur diesel (ULSD) so that you can play more and worry less.
ENHANCES PERFORMANCE
Whether during rain, snow, or shine, Opti-Lube XL Xtreme Lubricant Formula delivers. It works to improve the performance of your truck all year round. This fuel additive also helps separate water from Diesel fuel as a demulsifier and more than doubles the storage life of standard diesel fuel.

I'm not sure how its possible, as their product is the best on the market, but their customer service quality is on par with their product. I'm not a spokesman for optilube, but you won't ever hear me say anything negative about their product or staff.

Just like all their other products, LEGIT. Mixing it with Boost for even better results while remaining affordable per gallon of diesel.I'm using this combo during the spring/summer time and XPD for the winter!

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.
