Hot Shot's Secret Everyday Diesel Treatment 16 oz. Squeeze Bottle 2 Pack, 6-in-1 Diesel Additive - Injector Cleaner, Fuel System Cleaner, Fuel Additive Boosts Cetane

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!

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. :)

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

After purchasing our 2012 VW TDI diesel at 140K miles I started researching best practices to keep these little engines happy. What I read was that the US has some of the crappiest quality D2 diesel on the world stage. Even Canada's diesel is higher cetane and lubricity rated than the States not to even mention Europe which has WAY higher standards than us. The weak point of these TDI engines seems to be the high pressure fuel pump (HPFP) that is crank driven to enormous pressure for the injectors to to their thing. If these HPFP parts fail on common rail engines they can literally grenade and throw shards of metal everywhere within the downstream fuel system ensuring a VERY expensive repair if not destroying the engine altogether. The lubricating property of the fuel plays an important part in keeping these pumps working properly. There even seems to be some data supporting Canadian operated TDIs have fewer failure rates of the HPFP than stateside fueled vehicles although nothing had been officially published to my knowledge. Sulpher in the diesel had beneficial lubricating properties but was bad for the environment and subsequently removed from D2 by the EPA much like leaded gasoline of yesteryear. So the second tank I ran in my TDI was Hot Shot's EDT. I can't comment on the comparative difference as I ran this from almost day one. What I like is the claimed increased lubricity and cetane boost that is supposed to bring our crappy D2 up to reasonable levels the rest of the world enjoys. Fuel economy seems fine but playing with a low spun turbo and the subsequent torque is sometimes too irresistible to give fuel economy a fair chance. Besides, I need to blow out all that accumulated carbon :) I like the fact that the Hotshot's EDT seems more concentrated and affordable than the competition. 1oz for a tank is almost a performance treatment for my TDI. It's a negligible cost for a fill up and I hope they keep it that way. My dislike might be the one thing other people love about this product and that's the bottle. The bottle is meant to be squeezed to get the measured amount in the top fill area so measuring is easier. My concern is the filler neck is not long enough to cram into the filler to avoid spilling without a funnel and diesel doesn't do many favors to paint. My workaround was to save the empty bottles from other gasoline treatments and use a syringe to fill 1oz amounts of EDT and place in the trunk of the car in double plastic bags. Seems to work fine although the kitchen was probably not the best place to do this since it doesn't smell like flowers. Next purchase will likely be the bulk bottle. It's kind of a shame we actually need this kind of protection now since the US fuel standards are almost non-existent. Even B1 blended bio diesel would be a huge improvement in lubricity but not available where I live. Thanks Hotshot's...Good stuff!

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

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 product to add lubricity to your fuel and protect your exspensive fuel system components.
