Diesel power plus additive
 

Any diesel owners here use a cetane booster diesel additive? Had an ad pop up on Facebook, one I chose not to ignore for once, willing to give it a go as it's so cheap at £17.99 which will last a year. Took this from thier website:

CETANE BOOSTER FOR MORE POWER
IMPROVES FUEL ECONOMY
FUEL INJECTOR CLEANER
REDUCES SMOKE AND EMISSIONS
REDUCED COMBUSTION NOISE
LONGER COMPONENT LIFE
FULLY RESEARCHED & TESTED

They say up to 9% better economy and 44% cleaner injectors, sounds promising, just wondering what other people use if anything?

Draigflag,

There are some additives that are reputed to work.

What company is this one from?

There is one that I have been meaning to try as well, I might take the plunge in the next couple of weeks and report back.

Apparently this one in particular is tried and tested by Cummins and has proven results. It's Diesel power plus, just put dot Co dot UK after it. Probably works similar to Redex, thus far I've done one Redex tank.

Another one I was recommended by an independent oil retailer was Forte diesel additive, I obviously need to do a bit more homework on the matter.

Didn't want to play with bottles each fill up. So I decided to take a look at Shell Diesel V-Power, it has all those thing in it and it cost 8 cent a litre more, about the same cost or cheaper than buying bottles of stuff. I started to use it at 17,000 KM

When I started to finish off my second tank of it, I notice big differences suddenly. No hesitation, even when cold, smoother acceleration, peppier, quieter engine noise, etc.

Yes I would probably justify the extra cost and use V-power, but my nearest Shell is a 50 mile round trip and they don't even sell it there anyway! I did fill up there just a few days ago, but they only had the standard stuff.

The one item they say about this product that worries me is
"Diesel Power Plus contains the most effective combination of ingredients to absorb water from fuel" From their website.
Now it depends on what they mean by "absorb" if it is pulling water into the fuel to help it travel through the system that is bad. You want something that will cause the water to stick together so the filters can stop it. You don't want any water getting to the injectors no matter how small. If you are looking for a additive look for one that helps separate the water out of the fuel not absorb it into the fuel.

It's a tried and tested product so should be sound. It probably means that it helps with condensation issues. I still havn't bought any yet, but my last two tanks I added Redex which pretty much does the same thing.

Numerous shops have told me ULSD causes premature injector and pump issues in older diesels. I run Power Service additive in my every tank.

Besides gunking up your oil and creating more tailpipe particulate matter, what is the purpose of sulphur in diesel? We don't have it here, and there are no sulphur related issues.

It isn't a matter of adding sulphur to fuels. Sulphur is an ingredient in almost all crude oil. The problem lies in removing it from the fuel. That process adds cost to the fuel. True, sulphur serves no useful purpose in fuel. Also true, removing the naturally occurring sulphur from fuel makes the fuel more expensive.

Removing the sulfur does increase the cost. Along with allowing the use NOx reducing catalysts, removing the sulfur also lowers the sulfur oxide and particulate emissions. It also means longer motor oil life. There are pluses to removing it.

Removing the sulfur also removes some of the compounds that provided lubricity to the fuel. Which helps protect the injectors and fuel pump. They are supposed to be replaced after the sulfur is removed, but that may not have happened in the early days of ULSD here. So people had problems. Right now, off road ULSD should be the only thing to be careful with, since it can be ordered without the lubricant additives in it.

So most of these small effecient Euro diesels here probably only fail the PM/N0X standards over there because of the fuel quality and/or sulphur content? No wonder VW had to cheat haha.

No, ULSD is as low in sulfur as what you get in Europe.
VW cheated because when the US went to ULSD they also required diesel cars to meet the same emission standards as the gasoline ones. While a diesel will breeze through the carbon monoxide one, the NOx one proved to be tougher. It could be done, and other makes have done so, but VW didn't feel they had too.

I use Power Service in my VW TDI and though I haven't really seen an increase in mpg, I do feel it in the way the engine runs.

There is a user on tdiclub that cleans injectors and says he can tell a significant difference between those who routinely use an additive/cleaner and those who do not.
