What Matters Most When Choosing a Fuel Additive for Your 6.7 Powerstroke?

Selecting the right additive isn’t just about brand names—it’s about specific features that impact engine health and performance. Each factor influences how well your engine runs under demanding conditions.

Injector Cleaning Power

Injector cleaning plays a vital role in keeping fuel injectors free from clogging, which otherwise disrupts the precise spray patterns needed for efficient combustion. Clogged injectors cause rough idling and poor engine performance.

Deep cleaning agents are designed to tackle this by breaking down varnish, carbon deposits, and other buildup inside the injectors. For instance, Hot Shot’s Secret Everyday Diesel Treatment works at the molecular level to dissolve stubborn residues, restoring smooth fuel flow and consistent atomization.

The result is improved fuel delivery, better throttle response, and reduced emissions. Skipping injector cleaning often leads to uneven fueling, power loss, and rough starts, which can harm engine longevity over time.

Cetane Boosting Capability

Cetane number shows how fast and efficiently diesel fuel ignites when compressed. A higher cetane rating means the fuel lights off quicker, reducing ignition delay and promoting smoother engine starts.

Additives such as Hot Shot’s Secret and Ford Genuine Cetane Booster can raise cetane levels by several points. This adjustment improves ignition timing, which is especially helpful during cold starts or when hauling heavy loads.

The result is better combustion, smoother idling, and less knocking. Without this boost, engines experience rough running and increased wear, which can hurt fuel efficiency and overall performance.

Fuel System Lubricity

Fuel system lubricity is all about minimizing friction and wear in your fuel pumps and injectors. This is especially crucial when using ultra-low sulfur diesel (ULSD), which tends to remove the natural lubricants that protect these parts.

Using additives like Opti-Lube XPD introduces lubricating agents that help keep critical components running smoothly. Many of these additives also come with corrosion inhibitors to safeguard metal surfaces from damage over time.

Neglecting proper lubricity leads to increased wear and tear on your fuel system. This can result in premature failures, forcing costly repairs or replacements of injectors and pumps that could have been avoided.

Corrosion and Rust Prevention

Rust and corrosion form when moisture and contaminants mix with diesel fuel, causing damage inside fuel tanks and lines. This can clog filters and harm injectors, disrupting engine function.

Additives like Hot Shot’s Secret Everyday Diesel Treatment and STA-BIL Diesel Fuel Stabilizer contain corrosion inhibitors. These chemicals bond to metal surfaces, building a protective barrier that slows down oxidation and keeps rust at bay.
