Customer Reviews
Engine runs so smooth now
I ordered the Stiction Eliminator after seeing some reviews online, and wow, what a difference! My truck was running a bit rough, but after putting this in, it's so much quieter and smoother. I'm really impressed with how well it worked. I will definitely be buying this again, and I've already told my brother he needs to try it for his diesel.
Consistent performance, as always
Another great experience with Hot Shot's Secret. I've been using their products for years now, mostly the Everyday Diesel Treatment, but this time I tried the Diesel Extreme for a deeper clean. Just like all my previous orders, it arrived quickly and was well-packaged. My truck runs noticeably better after a treatment, and this one was no exception. It's why I keep coming back; I know I can count on them for quality products that actually do what they say. Always a reliable choice for my diesel.
Got my oil analysis kit
I picked up one of their Oil Analysis Kits to see how my engine was doing. Shipping was pretty fast, it got here a day earlier than it said. The kit had clear instructions, which was good because I'd never done one before. Sent it off, and got the results back in about a week. Everything looked okay, which was a relief. It's a neat service to have, makes you feel a bit more confident about your vehicle's health. Might get another one down the road just to keep an eye on things.

Anyone know if they do military discounts? Tried looking on the site but couldn't find a super obvious spot.
Thinking of trying their FR3 Friction Reducer. Is it really that much better than Lucas Oil or Royal Purple? Feels like a lot of brands claim the same thing.
What's the typical shipping time for these guys? Need some Everyday Diesel Treatment ASAP for a trip next week, I'm in Houston.
Ordered some stuff and got a free shipping code, but now I found a 10% off code from a Youtuber. Can I use both? Or is it one code per order?
Hey guys, thinking about grabbing some Stiction Eliminator. Anyone know if it's safe for older gas engines, not just diesel?
