Review: Diesel fuel for finicky diesels is getting tougher and tougher for me to find. Lots of expensive junk fuel out there. My Jeep Eco-diesel is a beast, but have to be watchful for good fuel. This additive has helped huge. I’ve used it for (3) years, and even tho it doesn’t suggest it, I use it in every fill up. No problems in 100K, and it get better than advertised MPG, and performance. Wouldn’t leave home without it!
Review: Run it in all my diesel equipment welder, truck, tractor and always notice a big difference after that tank of diesel is used. Noticeable performance and mileage gains Reduces smoke, noise, and rough idle. I believe it’s a powerful all-in-one cleaner and conditioner that actually earns its “extreme” name. Ideal for off-road, diesel truck owners, and anyone who wants to keep their engines running clean and strong.

## Questions & Answers

**Q: We heard that this product only needs to be used twice a year, does anyone know if it says this on the bottle?**
A: So?? Which came first?!  My bottle says 6,000 miles… this bottle is about 10 months old. 
I’d really like to know if the manufacturer recommends 6k or 6 months! 
Thanks

**Q: Would this product be suitable for a 1.6 Diesel engine in our family car?**
A: I use it it a 1.9 TDI and 2 7.3 diesels.

**Q: Has anyone used this with a TDI with DEF / Urea?**
A: It is specifically designed for restoring the performance of diesel engines so yea it will be fine in your TDI just make sure you follow instructions don't mix it too strong or your car will run like a raped ape for a minute

**Q: I want to use this in a diesel parking heater to try and remove some of the carbon buildup inside the burn chamber. Do you think this would do that?**
A: It is very unlikely that using Diesel Extreme will remove carbon that is already built up in your heater. It is best used as a preventative to combat the amount of soot/carbon build up. Another note is that unfortunately, Diesel Extreme is very odorous and using it in an open heating element may cause some unpleasant odors.

### ⭐⭐⭐⭐⭐ Review
*by D***D on 28 December 2022*

I used Hot Shots Diesel Extreme Clean and Boost when I had a engine light come on. I had taken my 2014 Ram 2500 for a oil change. It was odd that I had a engine light on when I picked it up. I was told it was most likely caused by a faulty EGR valve. After asking the cost to repair and what was involved I went to looking for a possible alternative solution. In my research I saw the sprays and cleaning that needed to take place. In my research is when I came across Hot Shots. It sounded like a good option, and thought what the heck. I tried the EDT but with the small amount of driving I was doing around town I didn't think it had enough chance to do the job. I was going on a 1,200 mile trip so I ordered the extreme. I added the Extreme Clean and boost and hoped for the best. I wasn't sure what to expect but was hoping it would do its thing and the engine light would be eliminated. Long story short I was around 300 miles into my trip and still had the light. It was about this time I stopped to refuel. To my surprise and delight the engine light didn't come on. I went on the rest of my trip and the light is still off. I am happy and a strong believer in the product. I use EDT on fill-ups and happy I was able to come across this product. Thank You Hot Shots!
