Best Diesel Additive

We’ve been testing Hot Shot’s Secret Everyday Diesel Treatment in our trucks, and we’re impressed with the results. This additive claims to boost cetane levels, which we noticed through improved fuel economy. Our trucks seemed to run smoother and quieter after using it for a few tanks.

One thing we really liked was how it helps protect the fuel system. The added lubricity is great for keeping pumps and injectors in good shape. We also noticed less smoke from our exhausts, especially during cold starts.

The squeeze bottle can be a bit tricky to use without spilling. We found using a funnel helps get the right amount in the tank without making a mess. While it worked well for us, some drivers might not see dramatic changes, especially if their engines are already in top shape. For the best results, we think it’s important to use this additive regularly.

When we tested Hot Shot’s Secret Diesel Extreme in our truck, we were amazed by the results. This stuff really packs a punch. We noticed a smoother idle and more power right away. Our fuel economy went up too – we got about 2 more miles per gallon on our next tank.

The cetane boost is no joke. Our engine fired up faster and ran more quietly after treatment. We also saw less smoke on startup, which was a nice bonus. The deep cleaning action seems to work well. Our truck had over 100,000 miles, but it felt like new again after using this additive.

We like that it treats a full tank and lasts for 6,000 miles. That makes it easy to use – just pour it in when you fill up. The price is a bit high, but we think it’s worth it for the results. Just be careful not to spill any. The smell is strong and it can stain. Overall, we’re sold on this product and plan to keep using it in our diesel vehicles.

We’ve tested the Archoil AR6500 in several diesel vehicles, and we’re impressed with its performance. This 40.6 oz bottle treats 400 gallons of fuel, making it a good value for frequent drivers. We noticed smoother engine operation almost right away.

One of the standout features is its ability to clean the entire fuel system. It tackles deposits in injectors, turbochargers, and diesel particulate filters. We saw a reduction in regeneration cycles in vehicles with DPFs, which can lead to better long-term engine health.

The cetane boost in this formula is noticeable. Our test vehicles showed improved acceleration and responsiveness, especially under load. We also tracked fuel economy over several tanks and saw a consistent improvement of 1-2 mpg in most cases. While the initial cost is high, the fuel savings can offset the price for many users.

We tried the Archoil Diesel Fuel System Kit in our truck, and we’re impressed with the results. The kit includes two products: the AR6500 Diesel Treatment and the AR6400-D Diesel Fuel System Cleaner. Together, they pack a powerful punch for diesel engines.

After using the kit, we noticed our truck ran smoother and quieter. The engine seemed to have more zip, especially when accelerating. We also saw a small bump in our fuel economy, which is always a plus.

The AR6500 treatment is easy to use. We just added it to our fuel tank, and it went to work. It’s meant to boost cetane and clean key parts like injectors and turbos. The AR6400-D cleaner tackles built-up gunk in the fuel system. We liked that it’s not just a quick fix but helps keep things clean over time.

We put Hot Shot’s Anti-Gel to the test during a recent cold snap, and it lived up to its promises. This amber-colored additive mixed easily with our diesel fuel, and we noticed smoother starts even on frosty mornings.

The built-in dispenser made measuring a breeze, though we found it helpful to use a separate container for precise dosing. We added 2 ounces per 55 liters of fuel, which seemed to work well for temperatures around -20°F.

One thing we really liked was the boost in engine performance. Our diesel truck ran noticeably smoother and quieter after using Hot Shot’s Anti-Gel. The increased cetane number gave us better cold starts and improved fuel efficiency.

While it’s on the pricier side, we think the peace of mind is worth it for diesel owners in cold climates. Just keep in mind that if you’re in an area where diesel is already treated for winter, you might not need this product.

We’ve been using STA-BIL Diesel Booster in our trucks and equipment for months, and the results are clear. Our engines start more easily and run more smoothly. The additive does a great job keeping fuel fresh, which is super helpful when we store diesel for long periods.

One thing we really like is how it cleans the fuel system. We’ve noticed less gunk buildup in our tanks and injectors. This means better fuel economy and fewer trips to the mechanic. The lubricating effect is a nice bonus too – it helps protect engine parts from wear and tear.

We found it easy to use. Just pour it into the tank before filling up. A little goes a long way – one bottle treats 320 gallons of fuel. It works with all types of diesel, including biodiesel blends. This versatility is handy if you have different vehicles or switch fuel types. While it’s a bit pricey, we think the benefits make it worth the cost for most diesel engine owners.

We’ve been using Power Service Diesel Kleen+Cetane Boost in our diesel trucks for months, and the difference is clear. Our engines run smoother and seem to have more pep. The 12 oz bottles are easy to use – we just pour one in at each fill-up.

One thing we really like is how it cleans the fuel injectors. Dirty injectors can cause all sorts of problems, but this additive keeps them spotless. We’ve noticed better fuel economy too, which helps offset the cost of the product.

It’s important to note that this isn’t a winter anti-gel additive. For cold weather, you’ll need to switch to their white bottle Diesel Fuel Supplement. But for year-round protection and performance, we find this product hard to beat. The pack of 9 bottles is handy, lasting us several months of regular use.

We’ve tested Power Service Diesel Kleen + Cetane Boost in various diesel engines, and the results were impressive. After just one tank, we noticed our engines ran more smoothly and started faster, especially on cold mornings. The power boost was noticeable, making our trucks feel more responsive when hauling heavy loads.

One thing we really liked was how it cleaned up dirty injectors. In older vehicles, we saw a clear improvement in fuel spray patterns, which led to better fuel economy. It’s great that this additive works with all diesel fuels, including biodiesel blends, making it a versatile choice for any diesel owner.

While using this product, we did notice it’s not meant for very cold weather. For temperatures below 30°F, you’ll need to switch to their winter formula. Also, the price might seem high at first, but considering the benefits and the fact that it’s a six-pack, we think it’s worth the investment for most diesel drivers. Just keep in mind that results can differ depending on your vehicle’s condition and how you use it.

We’ve been using Stanadyne Performance Formula in our diesel vehicles for months, and the results are impressive. Our engines start faster in cold weather and run more smoothly overall. The power boost is noticeable, especially when towing heavy loads.

One of the best things about this additive is how it helps with fuel economy. We’ve seen our miles per gallon improve by about 4% on average. That might not sound like much, but it adds up over time. The formula also keeps our fuel systems clean, which should help our engines last longer.

The half-gallon jugs are great for those of us who use a lot of diesel, but casual users might find them too big. It’s also not the cheapest option out there. But given how well it works, we think it’s worth the extra cost. Just remember to use it regularly to see the full benefits.

We tested Hot Shot’s Secret Winter Defense in our diesel truck this past winter, and we were impressed with its performance. Even when temps dipped below zero, our engine fired up quickly and ran smoothly. The anti-gel properties really shine, keeping fuel flowing freely through filters and lines.

Beyond just cold protection, this additive packs a lot of benefits into one bottle. It gave our truck a noticeable boost in power and throttle response. The cetane increase helps with quicker starts and less smoke. We also noticed slightly better fuel economy over time.

One bottle treats up to 200 gallons, so it’s easy to use. Just pour some in at fill-ups. While it costs a bit more than basic additives, we think the all-in-one formula is worth it. For diesel owners in cold climates, Hot Shot’s Secret Winter Defense earns our recommendation as a top choice for winter protection and year-round performance.
