Hot Shot's SecretDiesel Extreme 1 Gallon, Concentrated Fuel System Cleaner, Diesel Fuel Additive, Injector Cleaner - Increases MPG & Restores Engine Performance

I just got this product and I must say, it worked a little too well. For context, I live on a tropical island in the Caribbean. So poor quality diesel and short journeys are normal for us. With about half a tank of diesel, I put this product in my 2021 Nissan Navara Pick-up which has been sluggish because of the DPF system installed. I left the pick-up warm-up for a few minutes before I hit the road. I notice a difference in performance instantly on my take-off from my garage. It felt so different, that I honestly got nervous and went straight to the gas station to fill up. Let's hope the improvement continues. I may update if anything drastic happens.

Works great. Noticed a difference in power within a few miles of driving.

Fuel additives specially designed to clean fuel injectors must be used continuously and timely during fuel up intervals to be effective.

I use this stuff faithfully in my trucks. They run cleaner, less injector problems. And this was by far the best price i found.

Was recommended.

07 Cummins had a low cylinder due to the injector. Poured this in a little stronger than recommended took it out a drove the mess out of it for a little over 100 miles. I rechecked it on the scanner after the drive and the cylinder had picked up. I was doubtful many years as a mechanic I don’t believe in mechanic in a can but a diesel mechanic I know said he recommended it so I gave it a try. It’s now several months later and the truck is still running great.

This stuff is amazing! I thought nothing could beat Liqui Moli Super Diesel Additive but this does on value for the money and the torque increase is as equal to SDA. I use this in my mint condition 2015 Golf TDI. I did not think anything could quiet my engine but after this I can barely hear it on idle yet it screams when I drop the foot pedal. I’ve used Costco’s premium diesel religiously for years but this significantly increased torque. It states to run it every 6,000 miles that’s every 12th tank of gas in my TDI. I use about 4.2 oz per tank of gas so it’s dirt cheap. My main goal is to keep carbon deposits at bay so the performance increase is legendary. I added about 2-5 mpg on average getting getting 50 mpg with gas saving driving including speed limit on freeway and coasting. When I’m done with this bottle I’m going to try the every day version and I’ll report back.

Product worked great, a must for any diesel owner. Very important if the vehicle sits at all.
