Questions & Answers

Would you be able to store something in here? My boat is equipped with a 300-gallon tank for the diesel engines, which have 315 horsepower. I will be storing the boat during the winter months. ?

It might be best to contact the manufacturer, since I do not know. The company was very patient with me in answering my questions when I contacted them and I was very hesitant about trying this stuff. I therefore suggest that you get in touch with A quick "search" on Google revealed the manufacturer's email address, which I found very helpful. It would be nice if he could help.

What do you do with it? Do you pour it into the gasoline container?

This is the diesel fuel you pour into the Gas engines are not suitable for using this product.

If you're using diesel extreme alone or along with any anti gel additives, can you use it?

Since I just used the fuel additive, I do not know if it worked. It was effective almost immediately (5 miles later). Adding the fuel additive to the fuel is I mentioned in my answer to another question, I have the oil supplement, but have yet to use it, since the fuel treatment has already dealt with all of the problems I was having with hard starting and black smoke. I wish you the best of This may be of some help.

Shelf-life is how long it takes for things to go bad Is an open bottle still useful after it is opened?

I'll buy more if it works great
5/5

I woke up this morning looking forward to the first day. I halted the smoking when I turned it on This version sounds better overall, and the response time seems to be faster too. For a few days now I have been using it in my truck, and I have noticed a tremendous difference. The fuel gauge used to show 20 seconds of smoke when I started it in the morning, now it shows zero smoke. Great stuff might use during every oil change after 300000 miles and it runs just fine.

I brought my 35 year old diesel boat engine life back to life with this product
5/5

For example, I used it on my Universal 3 cylinder diesel (a Kubota family engine). With around 900 miles on the clock, my engine is quite old. (There was no black smoke) It was getting around 1/2 gallon of gas per hour at 2600 rpm before treatment In my case, I used 1/2 of the bottle to treat 22 gallons (full tank) of diesel and ran the engine hard at 2600 rpm for 30 minutes. The speed for four wheels should be 3000 rpm After 5 hours, I started to notice a slight change, probably a more responsive throttle. But after running for 8 more hours at 80% max rpm under cruising conditions, I noticed a smoother running engine, a more agile power plant and a decrease in In my experience, I am happy with this product and will continue to use it with my old engine. I will purchase.

When it comes to Deisel, it would be crazy for you to not use it! It's just amazing stuff, I must say! The Ford F250 Deisel pickup (with 125,000 miles) was running quite rough, and I was told that it was probably the injectors that needed to be replaced for You're all set! Then add to that the fact that the truck started to emit dark, black smoke when it started The vehicle was hard accelerated at one point
5/5

It was essential to get rid of something I can make more money with my wallet or the injectors. As a last resort, I searched online for a cheaper solution, and I discovered the 4x4 blog that praised Hot Shot Secret gas additive & fuel additive Adding Hot Shot Extreme to your oil will make a big difference. Both remedies were used and, almost immediately (half a tank later), the black smoke and difficult starting ceased. This stuff has become a holy grail for me! This is a highly recommended book! This is the best deal you'll find anywhere!.

The leaky injectors of my car have been fixed
5/5

This engine was built in 2004. The time is 9 hours. There was white smoke coming out of my truck. Injectors were the first thing I started looking into when I saw the diesel extreme ad and read some forums. I installed it and within a mile my truck started running smoother, the smoke dissipated, and the rattle of the injectors stopped. Having filled my tank of gas, I didn't worry about it anymore. Once or twice a year, when the engine starts to sound a little louder than normal, I use it. Diesel clean is the product I use on most fill ups.

You will no longer experience turbo lag
5/5

Despite having 15k miles on it, my new Ecodiesel began to run poorly. There is no sign of any fuel treatment from the previous owner. They installed this and they eliminated the turbo lag and got better mileage as a result. The average MPG was 27 I was getting if I was babying the car.

I give it five stars
5/5

This is an extremely high quality fuel that makes my Duramax exhaust like rocket fuel. It is made in the united states. I think this is an excellent product!.

System is cleaned from top to bottom
5/5

The fuel filter was changed after getting a bad tank of fuel, so I added this to the tank. A fuel problem was corrected and the system was cleaned. I'm still feeling the difference after drinking 800 gallons. In the future, I intend to purchase.

You have some good stuff here
5/5

It is great that they offer great products that can help my Duramax to run better and last longer, and I am happy to see that they have introduced this new fuel lubricant to our fleet.
