Does it do everything it says ?? I don’t know. Shipping was fast , product received in good condition and we use it every few tanks , cheap insurance for the price of trucks nowadays.

This is a great product for my diesel truck

This pairs very well with my 2018 International 4300 Durastar box truck. It has hit the 600,000 mile club and keeps going strong. I have started noticing my fuel tank guage no longer reads correctly and almost took a stab at replacing the fuel assembly unit for a few hundred. I went ahead and got some of this HotShot Secret and poured a 1/4th or 1 Qt for my 70 gallon tank. Beleive it or not, my fuel guage had restored its range after one tank. This pattern remained for about 12,000 miles until it started happening again. Used another 1/4th and got another 15,000 miles. The pattern is slowly going away so this shows that the tank is in fact getting cleaned out which was ongoing with affecting my sensor. MPG has not seen a rise. If anything it has seen a dip from 9.1 down to 8.9. But if it means burning clean with injectors and such, this is not a loss. Effective and great savings for the gallon. Looks good and easy carry size. No stickiness to worry about.

I’ve been using 4 type of diesel addictive for over a year. Diesel extreme every 4k or 5k miles. Everyday diesel treatment on each fuel charge. Winter defense on winter season. Winter diesel anti-gel when temperatures get below 10F. I have a more power, less black smoke and just look how my exhaust valve are. It’s a Detroit 60 series that works every day with 390k miles after overhaul. My truck is part our my family, feed my family and it deserves the best to keep running and running. I love this product

Second order of this product, it improves mileage and helps keep egr system clean.
