Hot Shot’s Secret Everyday Diesel Treatment EDT 16 oz Squeeze – Treats 400 Gallons – 6-in-1 Diesel Fuel Additive, Injector and Fuel System Cleaner, Boosts Cetane

For diesel owners looking to protect their fuel system, Hot Shot's Secret Everyday Diesel Treatment (EDT) is a heavy hitter in the world of additives. This 1-gallon jug is designed for the long haul, treating up to 1,280 gallons of fuel, which makes it incredibly cost-effective for daily drivers and fleet owners alike. The primary draw here is the 7-point cetane boost, which noticeably smooths out rough idles and improves cold starts. Beyond performance, it serves as a critical insurance policy against modern "dry" Ultra-Low Sulfur Diesel (ULSD) by adding essential lubricity to the fuel pump and injectors. It also features a demulsifier to help separate water from the fuel, preventing corrosion before it starts. While the 1-gallon bottle is bulky and requires a smaller dispenser for easy pouring at the pump, the peace of mind and improved MPG make it a staple for maintaining a healthy engine.

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!

I use all of their products. I have a 6.0 Powerstroke so I need all the help I can get! I use this in every tank and I have zero issues with my injectors. I also use their oil, and stiction eliminator. I use their transmission fluid, and antifreeze. Good quality products

Saved my injectors truck runs better than ever and better mileage I have used it for over 2 years worth every penny

I use it at every fill up. Works great

We have 10 tow trucks and a 500-gallon fuel tank at our shop, and we’ve been using this product for over a year now. You can definitely tell the difference in how our trucks run. It helps keep everything running smoother and more efficiently, especially with a fleet that’s constantly in use. Overall, it’s been a reliable part of our maintenance routine, and we plan to keep using it.

Didn't really believe the hype. Did a little research and watched Project Farm and decided to try. Im not a snake oil guy....but I will say my 2013 common rail TDI is quieter and I get a tad more fuel mileage. Does it pay for itself? Well, it does get better mpg, but I feel the reduction in noise most likely relates to less wear and tear and thats good enough for me. Im only using 1oz per fill up (about 14 gallons) so it lasts a very long time. I get 40mpg and im not light footed.

Great stuff and the company supports racers

Excelente producto, la única pega , es que el dosificador es en onzas/ galón. Siendo inútil en europa , que usamos el mililitros/ litros. Y el vendedor no se entera de la conversión. De todos modos os dejo la conversión 5 mililitros del aditivo / 10 litros de diésel.

I used this on some 3 year old fuel I had stored , treated it and have been running it in my truck , works great .

My cold start gets much better and good increase in mileage It will cover it's price by the fuel efficiency only Plus the cleaning effect on the injectors and lubrication of the diesel pump

I have been using this diesel additive consistently, and it’s been a solid upgrade for my personal vehicle and I have now ordered for my company trucks. The squeeze bottle design makes it super easy to measure and pour—no mess, no guessing. After running it regularly, I’ve noticed smoother engine operation, especially on cold starts, and less overall engine noise. It also seems to help with fuel efficiency a bit, which adds up over time. Knowing it’s keeping injectors clean and adding lubrication is a big plus. With the costly repairs to our emissions and DEF systems nowadays I believe the costs will be paid back through reduced downtime and shop costs.
