SEMA 2025: Hot Shot’s Secret Is Expanding Into Gasoline Engines

Known for its diesel-facing products, Hot Shot’s Secret is a well-known name. While they have a well-rounded diesel additive lineup, the team has identified a couple of holes that they are filling with products released at the SEMA Show.

First, is the company’s new DEFender additive aimed at maintaining the diesel exhaust fluid system. “DEFender eliminates the crystalline buildup often seen in the DEF system says Hot Shot’s Secret’s Guy Prenatt. “It also stabilizes your DEF fluid. What we’ve seen in the past 18 months on some of the newer diesels is that those injectors start to crystallize and clog up, and then the [DEF] injector isn’t spraying correctly. That causes the NOX sensor to read incredibly high, and causes false regen demands, causing more unneeded regen cycles. One ounce per 2.5-gallon cube of DEF not only cleans out the crystallization and saves you from replacing the DEF injector, it keeps you from having to clean out the SCR, because the exhaust builds all that junk up, too.”  

Prenatt then talks about the company’s new Diesel Injector Flush. Now, that might sound like a product Hot Shot’s Secret already has, but he explains, “It’s kind of like our Diesel Extreme, but on steroids.” By that, he explains, it’s intended as a service product, not an everyday use product. “This is for when you are having an issue, or your injectors aren’t running right. It’s meant to really clean everything out and get the injectors back to their base level,” Prenatt explains.

And then the headliner of the article, Hot Shot’s Secret Tick Fix + Protect. “This is really directed at the LS engine – we’re getting into gasoline vehicles now. It’s sort of like our Stiction Eliminator, but is pointed directly at that lifter tick found in LS and HEMI engines. It’ll get in there, take that varnish off and send it back to where it’s supposed to be,” says Prenatt, concluding: “It’s a big issue.”
