Best diesel additive

i pursume you done all ther srvice parts, also using vpower or aka nitro plus now, diesel might help. has its own detergants and cleaning agents.
yes its a little more, but for me in a petrol car it returns far better mpg to ofset the 5 liters i loose per tank

i recently had the teraclean service done on my pd130 mpg is a bit better and cars runs allot smother than before i have just ordered some diesel rhino so will see how it goes

What about using the liqui moly running the engine just on that while plugging fuel pipes rather than putting it in tank with derv, isn't there good results with that stuff?

had a good read what would everyone recommend for cleaning out a b7 with 94k on the clock , dare say its never been done since i took ownership.

Is the bg244 or rhino better?

For me nothing i have used before beats The Rhino for cleaning fuel system and general running. With regards the egr cleaning nothing beats popping it off an cleaning properly. Its pretty simple by all accounts and just needs some new seals. Not done mine yet ( on the list) But just putting the rhino through made the car feel better although my fuel economy suffered for first week, (heavy foot now i had more power . After that economy has gone up by a couple of mPG. gonna be treating the wifes a3 8l to a huge dose to hopefully clear the smoke issue it has.

I continue to use Diesel Rhino and I get good mpg out of a ten year old 1.9td1 130bhp. Proof: Bedford to Dover not going over 80 mph on speedo = 61.5 mpg. ( roadworks etc on M25 hold you to 50 for about 10 miles) Return journey going as fast as i could and combining that 61.5 came out at 54mpg. The cars is standard. I've probably put about 5 bottles of the stuff in it now but it pays for itself.

Diesel Rhino sounds very interesting! The guys that use it, do you fill up standard diesel or do you still stick to using premium diesel?

Diesel rhino brings standard grade upto premium so no dont use premium fuel because you get no cost benefit. If you use more than cetane than required it might reduce performance a bit. ( it wont damage your engine at higher doses in fact that is the recommendation for purging older engines) You save money overall because you don't pay the tax on the fuel but you get the effectiveness. Example: Rhino delivered 500ml is about £22.00 and in normal 1 to 1 ratio an 80 litre fill up would cost £3.60 in diesel rhino additive. A premium fill up would cost about £7.20 extra at current prices. No contest.

Cheers tbs! Do you use the stuff yourself?

Yes. Colder weather its good for warm up times and in warmer weather like today it does up the MPG by about 3 to 4 miles. The torque is where i notice it so I can drive on the flat in 5th at 1000 rpm more smoothly and thats where economy starts to work.

Sounds good. Think I'll order some to give it a try soon!

I use Diesel Rhino, I used it in the bora too.

Used to use normal Diesel from Esso etc and the extra Diesel Rhino but now use that money to pay the little extra for Shell V Power Nitro+ Diesel at £1.42 ish round here and get about 40 extra miles from less fuel so impressed with that......should have all the additives required.

I do find that different engines perform better or worse with different fuels as my last TDI preffered BP ultimate where my current TDI does not........odd but true for me.

I use liquimoly.
Get it on ebay and run the car soley on it.

FORTE is by far the best ive used many. Wurth's stuff is good too

i've used diesel rhino for a year now - very much improved the performance of my A4 1.9tdi with 115k. i used the 3ml per litre for a few tankfuls and then dropped to 2ml per ltr then down to 1ml per ltr. its brilliant, turns standard diesel to better than premium diesel. i completely recommend it

I pulled this from an email from a news letter i get from,power enhancer...


It was about time I aired an ongoing concern that has been boiling away inside me for a very long time. Those that have benefited from my consultations may already have heard it. That is a collection of paraphrased quotes that make my eyes roll every time I read or hear them. As soon as I do I just want to walk away because it can be tiring listening to such levels of ignorance, especially if the ignorance is compounded with an underlying antagonism or unwillingness to evaluate the evidence without bias.

Here are some of the quotes I am referring to:

“Why would you want to use an oil additive when oil manufacturers spend many millions on R&D getting it perfect?”

“There is no need to modify that X part on my Y vehicle because manufacturers spend millions on R&D and testing to get it perfect etc. etc..”

“If that fuel additive was any good it would already be in use in our fuels.”

If you subscribe to any of the above then congratulations, please go to the top of the class of automatons because you are the perfect consumer to many of these companies; a marketing department’s dream. This is said with all due respect and I mean that sincerely. Therefore, I am going to provide you with some food for thought and hopefully it will shed some well overdue light on this subject.

I’ll address the last quote first.

Putting it bluntly; if fuel companies already use the latest and greatest technologies then why do most of them sell premium versions of their own fuel?

Last year a fuel additive dealer that we know very well lost a contract to provide a complete fuel additive package to a fuel distributor in the Netherlands. The distributor was looking to provide a premium diesel fuel to its customers. The deal was lost to a competitor with a lower performing product.

So what was the issue? From the limited feedback it is understood that the fuel economy gained from the catalyst in the product was too high at around 5% and around twice that of the competitor product. They both cleaned, offered fuel system protection, handled water contamination etc. but the MPG gains were such that the distributor would actually lose money even with the extra they would charge for the premium fuel. Oh, a conspiracy!? No, and you are going to hear this mentioned a great deal in this article – IT IS BASIC ECONOMICS. The release of innovative technology is often balanced against strict economic criteria, targets and other similar constraints.

Do you see the difference? There was genuine intent on providing a better product but it has to fit in with an agreed financial model. This has nothing to do with conspiracy.

It is the same reason why companies that that PURCHASE energy or maintenance express an interest in fuel and maintenance saving technologies whilst companies that SELL energy or maintenance (or parts) can’t wait to kick you out of the door, if you manage to get through it in the first place.

Two years ago an extremely well known manufacturer of diesel fuel system parts, injectors, high pressure fuel pumps and so on sent a memorandum to all of its dealers and garages outlining the risks of fuel additives and indirectly prohibiting their use. Works of the devil, will cause damage and so on. Granted, there are additives that don’t deliver results as stated on the tin but I have yet to see fuel system parts actually damaged from their use. Unsurprisingly, there are tomes of reports of injector and pump damage from the use of poor quality fuels, contaminated fuels and hence fuels that are NOT fortified with high quality additives.

Let’s look at the second quote.

It is an interesting one to say the least and often parroted on automotive forums/discussion boards across the globe. My view is that it is only partly accurate so I will attempt to correct it.

“Vehicle manufacturers spend many millions in R&D and testing to make vehicles the best they can be WITHIN A DEFINED CRITERIA AND STRICT BUDGET”

Of course, huge sums of money are spent on vehicle technology and development but manufacturing quality and component durability is constrained by budget.

Firstly, technologies already exist to make a standard family car last for 20+ years, 500,000+ miles and without any major failure. The problem is that a basic family car would cost Ferrari money to buy. Who would pay £100,000+ for an uber-reliable family hatchback?

Secondly, the marketing departments know very well that 99% of their customers have no intention on keeping cars for 5 or even 10 years, hence there is no market for such a car. Consumer tastes change and people like to change their cars.

This keeps vehicles at “affordable” prices. To produce a car that no one actually wants or could afford would be commercial suicide.

Then there is the servicing and repairs, which is where the real revenue comes from. A lack of repair work would push the cost of the initial purchase up even further because the manufacturers and franchised dealers have to make money somehow. The use of additives and modified parts interferes with this business model. Again, this has nothing to do with conspiracy – it is basic economics.

Let’s looks at automatic transmission manufacturers as another example. Now, I am not suggesting they deliberately engineer transmissions to fail at 100,000 miles, but they certainly don’t engineer them to last hundreds of thousands of miles. Why, because they couldn’t afford to buy them within the budget that has been set. Car manufacture A is not going to go to transmission manufacture B with a requirement for a transmission that is robust for say, 250k miles, when most vehicles will never reach anywhere near that mileage anyway. Most manufactures provide a standard 3 year, 60,000 mileage warranty for a reason. It is common in the trade that a conventional auto gearbox (with torque converter), on original life-time oil is a ticking time bomb once it hits the 100,000 mile mark. The amount of double clutch transmissions that are failing much earlier is staggering. But hey, as long as it survives the warranty period [apologies for the sarcasm].

There are exceptions to this rule. An example would be the Bugatti Veyron. When the CEO set out the criteria for that car the designers and engineers were liberated from the usual financial restrictions. The primary criterion was simply to design and build a 1000 horsepower car using the best technology available regardless of cost. And the result? A car that despite its tremendous power output and complexity will probably go on for years without fault. And the result for Bugatti (or VW if we wish to be pedantic)? A car that sells for around £1,000,000 yet costs almost £5,000,000 to make. Clearly, this is not a sustainable business model for a mainstream manufacturer but you get the idea.

Now onto the first quote. Obtain the best or most expensive off the shelf oil you can find and I will improve the lubricity and extreme pressure rating of that oil within minutes by fortifying the additive pack. I can even reduce wear metals considerably over and above the best oil you can lay your hands on. I am not talking about the high end branded £50 gallon of “fully synthetic” oils but the specialist £25-30 per litre genuine fully synthetic (actual PAO/Ether based) oils. How can this be?

Firstly, the oil manufacturers do not have a monopoly on the latest technologies. Many of the patents in this arena are owned by smaller private companies.

Secondly, a high-end £50 gallon of “synthetic” oil probably contains less than £5 worth of raw ingredients. When you factor the sales margin of the manufacturer, master distributors, distributors and retailers, £5 turns into £50 when it reaches the shop shelf. There is nothing unusual about this.

Now look at the cost of base stocks. We buy genuine fully synthetic PAO base stocks by the drum loads and the trade price is around £3-£4 per litre. Take a major blender who will buy by the many thousands of litres and being modest, let’s say they pay £1.50 per litre. That equates to around £7 just for the base stock. Include the additive pack, blending process, packaging and other factors and you will end up with oil that costs £10+ to make. Pro-rata that equates to over £100 on the shop shelf but who is going to pay that?

The same principles that applied previously also apply here in that the same budget constraints exist with the manufacturing of engine oil.

Thirdly, most major oil manufactures actually buy in the ingredients and additive packs. There are two major suppliers in the world that supply the majority of additive packs to mainstream oil brands. You may have heard me mention this before in other articles but I will repeat it again here for those that haven’t. If you visit the largest automotive or mechanic orientated shows in the world you will find hundreds of different brands of oil but I guarantee that only a small percentage are genuine manufacturers. So much oil is actually rebranded and if you care to look closely you will discover that the oil market is just one huge marketing competition. Some of these marketing budgets make R&D budgets look like a petty cash pot.

Finally, and this is an important one. The various oil standards can actually restrict what you can and cannot do with oil and this can result in consumer lubricants that are inferior by design. For example, low SAP (sulphated ash) oils. Many of the good properties have been removed and replaced with more expensive yet inferior alternatives. When you are in the business and actually speak to the “right” people within the mainstream oil companies, some will openly admit to using cheaper technologies. The two main justifications are as follows: A. The market is not ready for the latest and greatest nano technologies and B: We have to keep costs down to be COMPETITIVE. Please understand that many oils are designed to meet specifications created by certain institutions (that I care not to mention in public), rather than designed to be the best performance wise. There is a difference!

Did you know that providing you committed to a minimum order quantity you could go to a variety of companies and order virtually any current spec oil you wished with your own brand design and it would be on your doorstep within weeks? Try asking them to blend a new innovative and superior technology into the oil and are you are politely shown the door.

It does concern me when I can take a pure 20W PAO base stock combined with an additive pack like AR9100, no polymers so a fixed 20 weight hot or cold, no additional HTHS additives or dispersants and so forth. Basically an unaltered PAO base stock with a high end oil additive that confirms with virtually none of the strict specifications, and yet it outperforms some of the best synthetic oils available and by a long margin. All proven with regular metal spectrographic and TAN/TBN tests. This oil wouldn’t just be unsuitable for most engines - it would be deemed dangerous to use by some of the regulatory bodies that own and control these standards. Welcome to the real oil industry.

Final note.

I am not asking you to believe me and if you think that I am way of the mark then I implore you to look for yourself because most of this is really common sense. Through the power of marketing many of us have become blinded and lost the classic art of observation, thinking for oneself and evaluating the data put under one’s nose. This also applies to anything I write here. Don’t just believe me – go and research for yourself.

In a future article I will delve into what oils and fuels I would recommend and why.

How has it effected your performance and efficiency? My 1.9TDi has 148k and I'd like to improve the performance and mpg a little

I've been talking to Ron from diesel rhino and I'm very interested in giving this a go.

He's recently bought an A3 and joined this forum. He also mentioned he would like to offer the chance of a forum discount to audi-sport users!

it seems to start better, and accelerates smoother and faster. it used to be very smokey but this only happens if i kick it hard now. mpg has improved too

i'd certainly be interested in a forum discount!

As would I. I know on other forums it was offered at ~£16. Even a 25% discount was offered!

I've read many stories on other diesel forums about DR being a success from their personal findings. I've read that it'll be smokey at times due to it cleaning some gunk out?

yeah, it seemed to get worse before it got better, but i don't notice it as much anymore.

+1 for a discount.

+2 I'd have a go if the price is right

+3
:-D

+4 yes id like to give this a go in my mrs a3 1.9tdi 130

I would try if there is a group buy

I've emailed Ron the link to this thread to show that some interest has started!

Correct that you will experience more smoke for a couple of tanks when you start using DR, but you should get this from any adatives that actually work and clean the system.

Also Ron is a good guy, so I'm sure he will open up a forum discount for you.

I'm halfway through a tank full with a concentration of 25ml per litre. I can definitely feel the engine pulling better and the idle is smoother and quieter. I dropped Ron a complimentary email.

Most people have noticed the same thing, which is good enough evidence for me to give it a go when I have the funds!

I could be convinced if a group buy appeared at the right price!

Just received this email which should interest people who are looking to give diesel rhino a go!

Dear All,

Many thanks to the person who alerted me to this thread via email.

I am Ron the from Diesel Rhino and would be more than happy to provide a forum discount for Diesel Rhino to the Audi-Sport.net forum.
Being an new Audi owner myself it would give me great pleasure in supporting the Audi-Sport community.

The last thing that I want to do however is to upset admin by not having such a discount approved by them before posting so if someone can suggest an admin to contact with regard to this I would appreciate it.

Kind regards.

Ron.

Hello Ron,

Quattrojames is usually online, perhaps you could drop him a pm.

Thanks, Mark.

Thank you Mark.

Message sent to quattrojames, awaiting his response.

Regards

Ron.

I've just been given a bottle of stuff off my Dad but can't find any info on it... it's called Unicat 4 Diesel anyone heard of it ???

I ordered some Diesel Rhino last week, topped up with the 30ml per 10l first dose and then filled the tank to help it mix better. Very noticeable difference, cold start very smooth where it was quite lumpy, acceleration much smoother and I'm sure its pulling better with more grunt. I would have said less noticeable smoke from my experience so far, even on 1st dose. My 1.9TDi Quattro is on 202k, with a new turbo recently, should give it a good clean out. I will report back once I've reduced the measure down over the next few tanks. If it continues to perform well I'll be taking up the potential of discount and buy myself a big bottle of the magic juice!

Only other thing is I know my clutch/DMF is nearing its end of life and I intend to replace this year, however I have noticed since using DieselRhino that I am getting more vibration/pulsing when engaging and disengaging the clutch or riding it when manouvering. Whether it is related I am not sure.
