Hot Shot's SecretHot Shot's Secret Everyday Diesel Treatment 16 Ounce Squeeze Bottle (HSSEDT16ZS)

I’ve been using Hot Shot's Secret Everyday Diesel Treatment in my Ford F250, and I couldn’t be happier with the results! This treatment has made a noticeable difference in the performance of my truck. It helps improve fuel efficiency, reduces engine noise, and keeps the fuel system clean. My truck runs smoother, and I’ve noticed a slight improvement in acceleration.The 16-ounce squeeze bottle is super convenient and easy to use—just squeeze the right amount into the tank, and you're good to go. I love how it’s designed to be used with every fill-up, making it simple to maintain the health of my engine. Plus, it’s great for combating the harsh effects of diesel fuel, especially in colder weather.Overall, this is a must-have for any Ford F250 owner who wants to keep their truck running in top condition. It’s affordable, effective, and easy to use. Highly recommend!

Noticeable difference in performance and mileage per gallon. Definitely a must for any diesel owner.

If you simply follow the directions, then this is an excellent product! If you intentionally use too much thinking that more product has to be better, well, then you deserve what you get and very likely you'll end up killing your expensive fuel injectors or the equally expensive fuel pump as a result. Follow the directions for use exactly and measure out the correct amount of product. This is not going to repair years/decades of neglect and pre-existing internal fuel system corrosion/damage/wear issues, which should go without saying, but I've read the low-rated reviews, which are few.Got the 32oz bottle to try, as better value compared to the smaller 16oz bottle/squeeze bottle. The only downside is you really need to follow the directions for use and measure out this type of fuel additive to avoid using too much of it per tank, which is significantly more difficult with the larger bottle size. As others have noted the caps on the larger bottles don't seal very well, and product is not something you want to keep inside your vehicle (or anywhere enclosed really) unless you bag it and ensure it cannot fall over. Failure to follow the product directions (just pouring it in freely) can result in damage to the very expensive injectors and fuel pump, etc., which is also true of other branded diesel fuel additives as well.Follow the directions and you will very quickly feel the difference in throttle response compared to pump diesel. I use the top-tier diesel fuel and supplement with this product. I get much lower running noise, better fuel economy, less DPF regenerations, and significantly better throttle response. The driving 'fun factor' alone is worth the price of this product, but I actually buy it to protect my aging HPFP and original injectors in my '10 Audi Q7 TDI...those bits are kinda pricey to replace. I used Liqui Moly products prior, and those are great too, but more expensive, so now I'm on Hotshot's EDT, and my TDI loves it. :)

great diesel additive recommended by my mechanic at every fill up for the motorhome to add to the tank keeps everything wirking properly and lubed.

Product works as advertised, but the jug leaks. Cap doesn't get tight and the pour-cup is dripping where it connects to the jug. Smells up your car/truck, gets your hands dirty and drips into whatever you're carrying it in.

Great product, but they really need to create a better cap for these bottles, along with something better for the foil seal when you open it for the first time. Leaks very easily and smells pretty bad when it does spill, and the messy foil can fall into the bottle and eventually into your tank if not careful. A simple screw on lid would do.

Great additive to the diesel owner with no to little lubricant in American diesel it's a must treatment especially if your vehicle has the CP4 fuel pump why take the chance just add it in to your fuel. I add the treatment every other fill up have 87000 on my F-250 and no issues. Does add the treatment guarantee no fuel pump failure NO but it does lessen the chance. Great product have used it since day one.

Cheap insurance. My mpg went up a couple of gallons after the first tank. I recommend!
