Diesel Fuel Additive Reviews

The product itself works well - good fuel system cleaning and performance boost. However, the bottle design makes it messy to pour and I've spilled it a couple times. Results are solid though, which is why I keep buying it despite the packaging issues.

We use this in our commercial vehicles and the results speak for themselves. Better fuel system cleanliness, improved combustion, and fewer maintenance issues. The concentrated formula means you don't need much per tank. Highly recommend for fleet operations.

If you run biodiesel blends like I do, this additive is absolutely necessary. Prevents fuel degradation and keeps the injection system clean. The antioxidant properties are particularly important for B20 and higher blends. Been using it for two years without any fuel-related problems.

My 15-year-old diesel pickup runs much better with this additive. Starts easier in cold weather and idles more smoothly. The fuel system cleaning properties seem to work well on high-mileage engines.

Used it for three months and saw some improvement in fuel economy but nothing dramatic. The engine does seem to run a bit smoother. For the price point, I was hoping for more significant gains.

Solid product that does what it claims. Engine runs cleaner and quieter after regular use.

Sometimes I notice a difference, sometimes I don't. The product might work better with certain fuel brands or engine types. Not terrible but not consistently effective either.

Been using this diesel additive for about 6 months now and definitely notice better fuel economy. My truck runs smoother and I'm getting about 2-3 more miles per gallon. The price is reasonable considering the benefits.

Really notice the difference in power and acceleration after adding this to my fuel tank. The cetane improvement is obvious during highway driving. Worth every penny for the performance enhancement.

My older diesel truck was blowing black smoke pretty badly, but after using this for a few tanks the emissions cleaned up noticeably. Still not perfect but much better than before.

The additive works fine and I do see some improvement in performance, but it's quite expensive compared to other brands. For the cost, I expected more dramatic results. It's good but not great value for money.

This additive has been a game changer for my fleet during cold weather. Prevents gelling issues that used to plague us every winter. The anti-gel properties work exceptionally well, and we've had zero fuel line problems since switching. Customer service was also very responsive when I had questions about dosage rates for different tank sizes.
