Does anyone here use fuel additives on every fill up?

I currently use LiquiMoly diesel purge every oil change. When I replace my fuel filter I fill it with the diesel purge and prime the system then throw the rest in the tank.

I've heard a lot of talk from diesel truck owners I know who swear by Diesel Kleen every tank of fuel. I'm having a hard time finding any real data on how these products perform or if theyre just snake oil.

In Indiana, I would be more worried about the presence of biodiesel blends > 5%-7%.

Have you noticed the warning about "no additives" on the fuel filler? And in the manual? Mostly that stuff is close to snake oil. It does raise the cetane a bit, but lots of people have gone many miles without any additives with no problems. Some people posting here and other places do use it, without any apparent problems. YMMV.

Snake oil? Nope I don't see snake oil here... Every diesel fuel has an additive package, it's your choice if you'd like to raise that value or not. Again, same stuff they use at the oil refineries...

If there were any convincing data, you can be sure the car manufacturers would recommend them and the aftermarket sellers would advertise with it. There is a long history of manufacturers recommending certain products, like Techron for valve deposits, when the stuff actually works.

Funny how all additive threads end up quoting the Spicer report - a totally invalid measurement since it was used on "base" unadditized fuel (not available commercially and clearly inferior to diesel with additive) with some of the additives making the lubricity worse, and only using one or at best two samples (I don't remember) for each additive....

Smart ass aren't you?

More like they can't test every single product to "recommend" additives because the compositions are different. I'm not saying use nor don't use them, but you my friend are knocking something it seems like you've never even tried. The tests are out there, check before spec...

I use AMSOIL in the whole car, tranny, rear end, motor and cetanium diesel additive. So far happy with cetanium.

This topic has been discussed many times on many different forums. Just do a google search for diesel additives and you'll find much discussion to sift through. Most people seem to be on one side of the fence or the other and are very adamant on their beliefs. Additives have many claimed benefits from water emulsification to cetane boosting to injector cleaning to keeping fuel from freezing etc. Some claim that there is no evidence additives have any benefits but there is really no evidence that a reputable product does any harm. I for one use them to increase cetane among a few other possible benefits. And if I am wasting my money, it's the equivalent of a cup of coffee a week.

What tests? Spicer didn't test 10 or so other parameters that are affected by and necessary with tailor-made additives. Please, I'm anxious to use an additive when proof (or any legitimate testing showing improvement) is produced.

Ad hominem attacks don't count, by the way....

Yeah, I guess warnings from VW, BMW, and Mercedes not to use additives mean that they do no harm. Lost you on that one, sorry.

In Europe, BMW recommends and sell diesel additive. It is just the LiquiMoly rebranded.

It is like the BMW gasoline engine fuel additive, the Techron rebranded to BMW.

You sound like a smart guy, why even repeat that rhetoric? BMW also tells you you never need to replace the transmission fluid, but are you buying that? I've chosen to use additives based on my own careful research. Others choose not too and that is fine by me. I'm not on a mission to change anyone's mind. Everyone should do the research and come to their own conclusion. Probably more important than the additive discussion is using good quality fuel, but as I have come to find, even if the pump says Shell or Chevron on it, you really never know where the fuel is really from.

Shell and others have a strict policy that if its not their fuel, it must be labeled as such on the pump.

Like I said, the industry has a long history of recommending certain additives, oils, etc. Its clear when talking with oil engineers that the companies take fuel composition and additives seriously. They would not risk producing poor quality fuel and compromise the brand name.

The reason a company would not recommend changing transmission fluid is more likely because it won't make a difference as often the torque converter wears out first, but this is my guess. Should I guess about additives also and tell everyone that its "research" then?

If one can question and doubt an automobile manufacturer's or oil company's recommendations, why not question the aftermarket additive industry, who stand to gain from sale of their products, also?

That is the key point All fuel has some additive package, a fact I confirmed with a fuel wholesaler in Baltimore -- it is just a question of whether there is benefit to the end user from supplementing it. I use PS and based on the dogged (though not utterly controlled) experiments of Dubfmaily on TDI forum I believe it gives me a small mileage boost.

That is true, but there is no guarantee that the owner of the station is following these policy's. Even Shell will tell you that it is up to the owner of the station as to what fuel he chooses to use. Some stations in my area have markings that says something to the effect "this pump may not be a Shell product" which is very nebulous. I try to avoid those pumps altogether. Other stations have pumps with the markings of the brand name when in fact I know they are not using the branded fuel. Realize this, the money for gas station owners is in selling items from inside, not fuel. A dishonest owner can draw more people into his store by lowering gas prices and using cheaper fuel in order to compete with the other guy down the street, while at the same time making everyone believe he's using the branded fuel. I've seen it done. I try and use a few stations that I feel comfortable with the product they are selling, but it is not always possible to use those stations. When I have to use a station I don't typically use and know nothing about, I take comfort in using an additive....but hey that's just me.

so...can we start a list of 335d owners who use additives, and what they use..?

Not worth it unless the forum supports stickys. Majority of threads just fall down the list

[TDIwyse]

One of the reasons I use an additive is because random sampling of available diesel in the midwest still shows a disturbing number of pump diesel being out of spec for lubricity and having cold flow properties higher than I like to see...

Saying that one wishes there was proof that additives actually make a difference isn't the same as saying one should not use them.

The $$ is not the only thing. We actually do not know what side-effects using additives can occur, whether its upsetting the delicate balance of fuel properties in favor of one, or worse things like CBU. Many additives s.a. Techron use heavy metals or molecules to work - and adhere to the fuel injectors, for example, to "clean them." There is reason to believe these metal "adhesive" particles can also attach to other metal surfaces. Most posters that complain of CBU never mention any details about how they care for their cars, not to mention any additives or "off-brand" fuel.

Of course this is pure guesswork on my part but the idea that extra additives are NEVER tested for long term effects is very significant to me (PS at least tests batches for compliance with required fuel properties). Disposing of perfectly good plastic bottles after using unnecessary additive is not environmentally friendly, and there are still some of us in the diesel community that might care about this. I just hate wasting my time and resources, and don't buy my coffee by the cup at Starbucks either.

Cheers,
