Questions & Answers

How much antigel does it contain?

There is an antigel with the winter formula, so very cold weather can be dealt with

What are the results of using this with DEF (diesel exhaust fluid). The Duromax I own is a 2011 model. I live in California. ?

In the same way that many other popular additives are used in pick-ups, the use of DEF is unaffected by its use. It is a part of the "after-burning" process in any modern pickup. There are several additives that can help keep injectors lubricated during use, as well as help keep them clean, aid in cooling, and lastly lubricate injectors, all components of any good diesel fuel Stanadyne additive is among the best. Gasoline - the fuel used in combustion Fluidization of pumps &amp valves The injectors - This prolongs the life of the injectors by cooling them! While some additives increase cetane ratings, you shouldn't bother with any diesel additives to make your engine perform better! Diesel exhaust fluid is injected after the engine's combustion process and should be used to help dissolve and burn off any particulates emitted during the combustion process.

What is its frequency of use? Do you mind if I fill up every time?

In fact, I always use 6oz when I fill up, because it is good for the engine and I get a lot more

What is the purpose of this if it doesn't Is it possible to use partially used containers after they have been opened? Would this be a better option than "diesel kleen"?

Because it stabilizes the fuel and holds the fuel formula, it will not increase lubercation. With the fuel capped, it should not affect the shelf life of the fuel. We have been using the boat for years for commercial fishing. A look at the label will give you more information, Mike.

The fact that it actually works
5/5

Among all diesel fuel additives, this is the only one that has shown to increase MPG and lower There are people who say that their trucks idle smoother and shift better than mine, but I can't speak for them. However, the product has proven to me that it is able to deliver the desired results exactly as stated. If you are still using your fuel filter for about 4 months, I would recommend replacing it The number of tanks is five.

There is soot
4/5

In order to eliminate the soot from my diesel engines, I bought this product. Although it does not remove the soot completely, it does a better job of removing it from my exhaust than anything I've tried so far. There is a cabin on the aft of our boat that is 50' long. We have a tendency to have soot roll up the aft end of our boat when aft cabins are in use. It is hard to describe the staion wagon effect for those of us who were old enough to recall it. It presents a big problem when traveling and running the train. As far as I have discovered, Stanadyne does a great job.

Until now, hope was bottled up
5/5

purchased this product in order to increase lubricity when I am running blended fuels during winter. As of now, I do not know if it helps. Those who want to burn hours and hours reading about diesel fuel additive use can do so by searching and reading about them. I'm assuming that you already have wasted those hours of your life reading this and are hoping someone will read this and the problem will be solved. To tell the truth, I have no idea if these things are in the tank or not.

In another review, the writer mentioned that he can tell if he forgets
5/5

In the winter of last year, I went on an expedition The 0 powered Diesel was difficult to start. If the temperature was below 50 degrees, I had to plug it in. With this battery, my truck started easily regardless of the outside temperature, and I didn't need to plug it in. Unlike another reviewer who mentioned the sting of forgetting to add this, I can tell when I forget to add it. It is easy to see the difference in ease of start and power. It was on a youtube video that I learned of this. It was highly recommended by com diesel mechanic. Having now understood why, I can move forward. Now that I have started my third bottle, I will never run my truck without.

I've tested it and it works
5/5

Fuel P is protected by using this. A second injector is also available. This stuff seems to work to me, but I've never tried it. Mechanics run the car the same way. The 2016 535 BMW diesel I own is a good vehicle. Some forum members say that unless you run stuff like this, the Cp4 fuel pump and the injectors on these cars can fail. it is always better to be safe instead of It is my intention to delete dpf and EGR completely in the near future. The engine is in Stage 1 now and the EGR is off to prevent the sludge from getting into it.

I give it five stars
5/5

It has been my go-to accessory every time I've filled up my Jetta with gas. Fuel mileage, starting in cold weather, and more are improved.

The first time I used this stuff, I was skeptical, but it worked
5/5

Currently, I own a 2006 Duramax LBZ with 170k miles, and this is the Once I used this product I noticed an improvement in the engine's sound. The engine ran smoother and didn't make any noise. Second dose of the drugs made the engine quieter and smoother. Calculating mileage differences is not something I have had a chance to do.

Even though it would be nice if it could be kept with your vehicle
4/5

In spite of expectations, I am only rating this product with 4 stars due to the fact that only time will tell whether the product is effective in helping prevent and control its effects in the long run. Having used Stanadyne just for three months now, the amount of smoke coming out of my exhaust has decreased and it certainly seems to have helped with my initial starting up. In spite of the fact it would be nice if you could have it available with your vehicle at all times, like many petroleum products you do not want to store it inside a vehicle or in the bed of a truck for too long, since the heat will damage it.
