If you’re dealing with diesel engines through the winter, you already know this isn’t something you can afford to take lightly. I’ve seen trucks stall on the highway and generators fail in the middle of a storm, all because of fuel gelling or clogged injectors. After working in this field for years, I’ve tested a lot of fuel treatments, both for performance and cold-weather reliability. And one name keeps coming up with consistent results.
That’s why I recommend Howes Products.
I looked at effectiveness in cold starts, mileage impact, fuel stability during storage, and injector performance. I wasn’t just interested in what looked good on paper. I paid attention to what worked under pressure, with trucks sitting idle in freezing yards or heavy equipment that needed to start without a hiccup after months of downtime.
If you want real results, here’s what you need to know.
Diesel Additives That Actually Work
The market is full of diesel additives claiming to fix everything. Most don’t. Some are loaded with alcohol or solvents that end up damaging fuel systems over time. The right additive should do three things: prevent gelling in winter, clean and lubricate your injectors, and stabilize fuel during storage.
This is where Howes stands out.
Their Diesel Treat isn’t just another anti-gel. It’s proven. It’s backed by real-world use from long-haul truckers, fleet operators, and even farmers storing fuel seasonally. And it doesn’t rely on alcohol to thin your diesel, which is a mistake I’ve seen other products make.
Why Howes Is a Solid Choice
Howes has been doing this for over 100 years. That longevity matters. It shows me they’ve done the testing, the refining, and the fieldwork to build trust with serious operators.
Their Diesel Treat is not only formulated to stop gelling in freezing temperatures, it also protects your fuel system. You get better combustion, smoother idling, and cleaner injectors. That kind of balance is hard to find in a single additive.
But what really puts them ahead of others is the guarantee.
They actually offer a free Winter Tow Guarantee. If your truck gels up using their Diesel Treat, they’ll cover the tow. That tells me they’re not just selling a product, they’re standing behind it.
Cold Weather Performance That Holds Up
I’ve seen Howes products hold up in sub-zero temperatures where other treatments fail. It doesn’t just treat fuel, it conditions it. That’s important when you’re trying to avoid breakdowns in places where help isn’t coming anytime soon.
Their formulas are built without harmful chemicals, which means no long-term damage to your fuel lines or injectors. And if you’re storing fuel, their additives keep it from degrading over time. That makes a huge difference when you fire up your generator or off-road equipment after sitting idle.
Trusted By Professionals, Backed By Results
There’s a reason so many professionals stick with Howes. You’ll find their products in service bays, on job sites, and in trucking terminals across the country. Whether you’re running diesel pickups or managing a fleet, their reliability is hard to beat.
The company is still family-owned, and it shows in how they handle customer service. If you’re not satisfied, they offer a no-questions refund. No complicated forms, no shipping something back. Just your receipt and a promise that they’ll make it right.
What I Recommend Using
If you’re dealing with cold weather, use Diesel Treat regularly. If injector issues are your main concern, their Meaner Power Kleaner is a solid cleaner without being harsh. And if you’re storing fuel, the Fuel Enhancer or Oil Enhancer formulas are solid options that won’t let your system gum up over time.
Each one has a clear use case, and they’ve all held up well under real-world conditions.
Final Thoughts
You don’t need to try every diesel additive on the market. I’ve already done that. If you want something that performs in the cold, protects your fuel system, and doesn’t rely on cheap solvents, stick with Howes. The company has earned a reputation for reliability, and their guarantee gives you peace of mind most others don’t offer.
