Powerstroke engines are renowned for their exceptional durability and power, making them ideal for long-haul applications. However, even the best engines have their shortcomings. Whether it’s rough cold states, hesitation under load or a gradual loss of power, these issues cause frustration. The good news is that using fuel and oil additives can address or prevent many of these problems.

Why Fuel and Oil Additives Matter for a Ford Powerstroke Engine
Common issues stem from the same root causes — fuel system wear, poor lubricity or the Powerstroke stiction. There’s a simple fix to these problems, and you can often DIY it with little up-front cost.
Fuel and oil additives are a cost-effective and straightforward solution. They’re a must-have for any Powerstroke owner because they protect the engine, restore performance and keep a truck running like new. However, with so many choices available, selecting the right product can also be a challenge. What are the best fuel and oil additives for a Ford Powerstroke?
1. Hot Shot’s Secret Bulletproof Your Powerstroke: The Best All-In-One Kit
The Hot Shot’s Secret Bulletproof Your Powerstroke kit lets you enjoy the raw power of a 6.7L Powerstroke, a 7.3L Powerstroke or use oil additives for older diesel engines. Stiction causes misfires, power loss and other engine problems. Fortunately, this solution provides a quick and effective fix, targeting stiction at its source. The kit combines oil-side and fuel-side treatments to lubricate and restore injector performance, helping your truck start and run smoothly.
The oil additive breaks down deposits in the HEUI system, allowing injectors to work properly again. Meanwhile, the fuel additive boosts cetane, improves combustion and cleans the entire fuel system, restoring engine performance. These benefits make Hot Shot’s Secret Bulletproof Your Powerstroke kit a leading choice. It works quickly and effectively, addressing two major issues simultaneously. Whether you’re dealing with stiction or want to prevent it, this additive is an excellent solution for your Powerstroke.
2. Lucas Oil Anti-Gel Cold Weather Diesel Treatment: The Best for Cold Weather
As winter approaches, dropping temperatures can cause problems for 6.0L or 7.3L PowerStroke engines. The diesel fuel thickens as the paraffin wax begins to solidify. This is known as gelling, and it can be a pain for truck drivers, making even reliable PowerStroke engines unable to start.
The Lucas Oil Anti-Gel Cold Weather Diesel Treatment is easy to apply yourself and provides a quick solution. For optimal results, select products designed to lower the fuel’s cold filter plugging point, keeping it flowing and preventing wax crystallization that can block your PowerStroke’s system. For anyone driving a 6.7L or older 7.3L Powerstroke in northern climates, using an anti-gel is essential.

3. Power Service Diesel Fuel Supplement +Cetane Boost: The Best for Maximum Cetane
Incomplete combustion can be a pain for any PowerStroke owner, especially for heavy towing operations that require a maximum boost. The Power Service Diesel Fuel Supplement +Cetane Boost is one of the best diesel fuel additives for Powerstroke engines with incomplete combustion.
While many diesel additives include a mild cetane boost, some situations simply demand more. These formulas are specifically designed to provide exactly that. With a concentrated dose of cetane, these additives help your diesel engine ignite faster and burn more completely. The benefits are numerous, including a sharper throttle response, smoother acceleration and better fuel economy.
4. Archoil AR9100 Oil Additive: The Best for Stiction Prevention
The Archoil AR9100 Oil Additive is another powerful additive for any truck owner. Many consider it one of the best engine oil additives for reducing stiction and wear in Powerstroke engines. This kit uses non-borate technology in an ester base to reduce friction and provide extreme pressure protection. Ideal for 6.0L or 7.3L Powerstroke trucks, this product enhances lubrication in high-pressure areas, thereby improving the performance of the injector and pump.
The Archoil AR9100 Friction Modifier also protects a Powerstroke engine against long-term wear, helping to maintain smooth engine performance throughout its lifespan. Particularly useful during cold starts or heavy-duty driving, this additive reduces stiction and friction, ensuring your truck is efficient and performs well.

Choosing the Right Powerstroke Fuel and Oil Additives for You
The right additives protect and optimize your Powerstroke. Whether you’re battling stiction in a 6.0L engine, preventing fuel gelling in freezing temperatures or looking to boost cetane for better performance, there is a specialized solution. By diagnosing your engine’s symptoms and matching them to the right product, you can effectively address common issues. Investing in the correct additive restores lost power, improves reliability and extends the life of your engine, keeping your Powerstroke running strong for the miles ahead.
