Hot Shot's SecretDiesel Extreme, 1 Qt (Packaging May Vary) (P040432Z)

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!

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.

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.

I have a 2012 f250 6.7 and it had a little miss at idle every once in a while. I ran this for 200 miles so far and had not hurt it since! WOW crazy stuff, It just show how bad are fuel is here in the US. I will update if something changes!

Was recommended.

I don't really know how this works inside the engine, but I feel the car quicker and more powerful from a "butt-dyno" point of view. Worth a try.

Affordable and good product

I would say very good stuf used for semi truck cleaned injectors pretty good
