Opti-Lube Boost! Formula Diesel Fuel Additive: Quart, Treats up to 640 Gallons (Quart, 1 Bottle)

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.

This additive makes my Toyota Hilux GR Sport faster and engine runs way smoother

Currently mixing boost and xpd with great results. I feel i did not need as much lubrication as xpd brings alone and boost uses less additive per gallon for $$ savings. Kind of my idea of POWERSERVICE PLUS CETANE BOOSTER, but with higher quality XPD PLUS BOOST. I do average mpg slightly higher with just xpd but the mixture gives me quicker detonation during injection (performance) and more of a jerk during downshift acceleration (faster response) . Application is N57 BMW diesel.

Will buy again

Works as it should. I mix with 2 stroke oil and this. Noticed a much better throttle response and overall smoothness to idle.

I definitely can feel more get up and go in my truck! Plus it boosted my fuel mileage by 1 mpg which is pretty good for a fuel additive in my book!

Engine was not quieter nor is there much improvement in fuel mileage or performance. The only thing that has made a noticeable difference in my car are Stanadyne products, and that's with increased performance. Mainly using products to keep the HPFP from an untimely demise.

Cheap insurance. You will improve mpg's with a cleaner burn and protect your injector tips from gumming and creating uneven injections. The cleaner burn will also result in less DPF regens meaning less overfueling; saving even more mpg's and saving your oil life and engine life.
