Hot Shot's Secret Everyday Diesel Treatment EDT, 5 Gallon

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.

Extremely impressed! MPG improved from 10.8 to 20.2 in my 2019 Chevy Silverado 2500HD! My mileage is actually higher even towing a boat!

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.

Would have given this 5 stars, however, if you plan on packing this in your truck, keep it straight up!!! If it tips at all, you will loose a lot of product, and it will stink. Great product, but they need to have a better seal on it!!!

I recently began using this in my 2002 Silverado 3500 Duramax/Allison 4WD dually, with 145K miles on the odometer. I bought the truck new and have made quite a few modifications to it over time…Intake, straight exhaust, power programmers, etc. I’ve used other diesel fuel additives in the past with varying degrees of success, but none that really blew my socks off. 😂 Within a half tankful (15-20 gal) after adding this magic elixir, I have a very noticeable increase in throttle response, as well as a noticeable increase in smoothness when accelerating and I tend to accelerate a lot! 😉 I even feel that it starts a little easier. I can’t speak to whether I have any increase in fuel efficiency yet , but I’ll update in a few weeks, should I find any significant change. Needless to say, I’m sold! I will be consistently using this additive in “The Beast” for the foreseeable future! 😀 I can honestly, highly recommend this product!!! 😀

I use this Hot Shot’s Secret Everyday Diesel Treatment for my diesel truck, and it has been a great product to keep on hand. The 1-gallon size is a good value because it treats a lot of fuel and makes it easy to use regularly. I like that it is made for everyday diesel maintenance, not just occasional use, and it gives me extra confidence that I am taking better care of the fuel system. A very practical product for diesel owners who want something reliable for regular use.

Excellent product for keeping my new 2026 Kubota tractor safe for fall and winter.

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
