Hot Shot's Secret Diesel Extreme 16oz, Concentrated Fuel System Cleaner, Diesel Fuel Additive, Injector Cleaner - Increases MPG & Restores Engine Performance

Got my Truck out of a Restoration shop after a year and a half , kept getting water in fuel light on . 1 use no more ligfht!! and truck runs noticably better

Stuff really seems to work - my diesel's exhaust had just a little bit of smoke and color, now even under heavy loads and surges it stays completely clear. Will buy this in bulk next time

First time use and very impressed with MPG and performance. Filled up and drove 540+ miles on a single tank avg 18.5-19.2 MPG. I believe this is beneficial to maintain and a preventive measure. This will not fix failed components already. Highly recommend this product after first use. Will update as time goes on for durability.

Great additive. Use it every month once. Good product to have with you in case of filling with bad diesel . Clears system right away. Better than Lucas in my opinion.

Seen a private test done on YouTube from a dependable source,,,,the other diesel additives are a waste of money.

I was looking for a good diesel fuel additive that would clean my injectors and burn at a hotter temp so I read lots of reviews and ended up getting this brand. I’ve used it on 4 tanks of gas and I have to say that my rig runs much smoother, starts easier, and I definitely have more horsepower. It’s almost like I’m driving a new truck…and my truck just turned 30 years old a few days ago. Definitely recommend this additive…I’ll be buying lots more of it!

Good product that seems to be doing a good job.

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.
