Hot Shot's SecretTrio Diesel Oil and Fuel Additive 128 Fluid Ounces

Engine has been running rough. 190,000 miles on 7.3 Liter Power Stroke. Added with last oil change and have used the fuel additive with one fueling. The engine ran smoother after the fuel additive was added. Next tank I was out of town and didn't put in additive. Ran rough again. Next tank put additive in with fueling and engine smoothed out again. Will be buying more fuel additive.

The best thing you can do for your 6.0 or 7.3 powerstroke. The injectors will thank you by lasting without having to be replaced. I now have 261,000 miles on my original injectors with no issues at all. I started using the oil treatment once the truck had over 150,000 miles. The injectors came back to life, no more hard starting after the first treatment.

If you have a Ford 6.0 Turbo Diesel then this stuff is what you need. International the company who actually designed the 6.0 hired this company to develop a chemical specifically for the 6.0 injectors. I bought a 06 F250 Super Duty with a 6.0l turbo diesel with 216000 on it. It had a bad vibration turned out 4 of the injectors were throwing codes. I tried a couple of other products and it made no difference. I saw this product on the Truck U tv show and thought I would try it. I followed the recommendation of Hot Shots to use full synthetic oil. I changed the oil added the hot shots stiction in the oil and the other in the fuel. The instructions said to take it out on the highway and drive 50+ miles. Before I could drive the 10 miles to the highway on ramp most of the vibration was gone. By the time I got back all the vibration was gone. I reset the codes on the computer. I am now at 223000 and no more codes. The motor is so quiet compared to before and runs from 0 to 80 smooth with no vibration. The third chemical is not really needed but was bundled in the pack. I poured a little in the PS pump but I have no opinion on it one way or the other. The fuel additive is a once a year deal. Not sure what this product will do for other diesels but it worked wonders for mine and it was specifically designed for the International 6.0 which ford adopted.

I have used the tune-up-trio and have been very satisfied with the results. My truck runs a lot smoother since using them. I gave the top rating because over the years I have tried many other additives and have never experienced this much change in how my truck has performed.

As always, great products. I use them in all six of my vehicles from a loader to a motorcycle

trying this again worked on 1 truck ,moving to my other 2

I did not receive the fr3 bottle they ended up giving me the trans additive instead. Don’t get me wrong I will use it, but just wish I got what was advertised. Hot shot secret is a great additive.

I used it on my Duramax very pleased would recommend this to everyone thanks.
