Hot Shot's Secret Diesel Extreme Diesel Fuel Additive

2007 lbz Duramax.I have used Diesel Extreme in my lbz one tank every six months.The truck runs like it did the first day I bought it new.No hard starts,no noisy injectors and no smoke issues.I've recommended Hot Shots to all of my family and friends.

2016 GMC Sierra 2500HD Duramax with 36,000 miles. I'm using Diesel Extreme, EDT and LX4. Instantly noticed less crank time on start up. I truly believe it runs smoother and I might go as far as to say the motor seems quieter. i can't say enough good things about the mileage. With our truck and Airstream trailer we are dangerously close to 15,000 pounds. We've be able to do quite a bit of traveling since adding your products. I have gained at least one whole MPG. I'm getting an easy 13.5 MPG with trailer in tow. Excellent products folks keep up the good work. I can't wait to try the Gasoline Extreme on my 2013 5.3 Silverado. Thank you again.

I found this to work great in my tractor and saw a much better start in my 2002 vw tdi (370,000 miles ish)! Only thing that I don't love is the container it leaked a small amount and was quite hard to pour into the tanks without making a mess! Over all well worth every penny!

I have always said don't use additives until my 7.3 started to have a little miss going up hills pulling a trailer. After the thought of replacing the injectors I asked around and found out about hot shots. After adding the product, I can't believe how well it works!

We were ready to throw in the towel on a T444E. Sluggish, nasty choking smoke at idle, smoke and crud from the slobber tube, overheating, coughing and bucking under acceleration. In the service bay for something daily with no results. ONE QUART of diesel extreme eliminated ALL symptoms in a single day. Driver swears that the horsepower has doubled and isn_
