Diesel Engines’ BEST Cure

2 years ago
Hotshot is by far the best additive for my 168k F250 Superduty. Filled my 50gal tank and the minute I started it up, I could hear the difference. But wait, that’s not it….I decided to try the additive at high speeds and wow what a difference. Smoother, cleaner, and I can already tell and feel the difference. Be a Hotshot, buy HOTSHOT

Yes, I recommend this product.

Noticeable difference in the way my engine was running and I don't think my system was even particularly dirty. Half a treated tank and my dd15 was humming. Will continue to use every 6k miles.

Forgot to order EDT on previous order prior to this purchase. I have used hotshot products with great results. The EDT has cut down the number of regenerations my 2018 Sierra Duramax performs. This proves that engine runs cleaner and improves fuel milage.

I was skeptical but not anymore

After the second tank of fuel, I started to notice that the truck seemed to have a better throttle response and more power. I haven't checked the fuel mileage, but the truck does run better. i'm very satisfied.

I have Caterpillar c12 in a 2004 Peterbilt with 1440000 miles on it with 4 out of 6 original injectors. The fuel i purchase in the area the area is mostly bio diesel and my engine doesn't like it. When i can buy real diesel I can really tell the difference in performance and fuel mileage. The problem is buying real diesel fuel. It's not readily avvailabe in my area. So I use EDT and Diesel extreme [when needed]. EDT makes my Engine sounds normal , performance is were I like it and I get way better fuel Economy. Last week it was extremely cold here [9 degrees]I forgot to plug my truck in and went to start it up and it popped right off surprisingly. I recommend Hot Shot Secrets to all my friends.
