## Description

Hot Shot's Secret Everyday Diesel Treatment 4oz, 6-in-1 Diesel Fuel Additive - Diesel Injector Cleaner, Diesel Fuel System Cleaner, Diesel Additive Boosts Cetane (HSSEDT16ZS)

Review: 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. :)
Review: Good value. I have used this in trucks and tractors and other equipment. It is a higher dosage rate than the regular EDT but I feel like along with keeping diesel from gelling up it is also some insurance as far as lubricity on the injection pump and other components and hopefully will help everything last a very long time. So far I have not had any gelling issues using this. I think the main thing to keep in mind is treat your fuel and use some to get it through the filter, pump, etc before it gets cold out. Make sure to treat per gallon and also for the cold expected.

Been using this stuff in 3 different diesel trucks. I cannot tell you whether it works or not, but my trucks still run and didn't blow up. So maybe it helped? It didn't blow them up ..... so there's that. I've never torn down my engines or looked at my injectors. Maybe that because I use this?
