Hot Shot's Secret Everyday Diesel Treatment EDT, 16 oz

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. :)

I’ve been really impressed with Hot Shot’s Secret Everyday Diesel Treatment. It’s easy to add to my fuel and gives me extra confidence knowing I’m taking care of my diesel system with every fill-up. I like products that are simple to use and practical for everyday driving, towing, and putting miles on a truck. I’ll definitely keep using it and would be excited to test and review more products from this brand!

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’ve been using Hot Shots EDT in my diesel truck for several years and love it. The easy-pour containers make dosing at each fill-up a breeze, and I’m confident it helps keep my engine as clean as a diesel can be. Reliable product I’ll keep buying.

Is a great concentrate and specs are like no other product but have not purchased this product without the “measuring chamber.” It does improve performance and utilize because the removal of sulfur in deisel fuel and lack of lubricant if fuel that decreases the life of mechanic fuel pumps and damage to plungers on injectors - extending life on expensive engine components.

When we bought a diesel pusher, a friend of ours recommended this to us to add to the fuel every time you fill up. It doesn’t take much directions are on the bottle and we think it works great. We originally bought the smaller bottle which has an automatic pre-measure on it now we buy the big one to refill the small bottle as it is a much better value. Whether you have a diesel truck or a diesel RV, you can’t go wrong with this product… Helps to keep your engine running smoothly and keep your injectors clean.

I dont even any studies or anything showing this product works great. All I can say is I've been using this on almost every single fill up since I bought my truck. I've had it for almost 7 years now. My truck has 190,000 miles now and I haven't ever had any issues with my fuel mileage, the Def system, or any other problems.

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.

Llegó en otra presentación que no es tan útil

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.

Just as described and exactly what i needed.

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

Engine runs smoother with Hotshots
