All these fuel/oil/coolant miracle additive have been proven that they're at best doing nothing except removing some cash out of your wallet. If you wanna lubricate your injection pump than use 2 stroke oil (mineral base not synthetic) like 200:1 ratio after you used injector cleaner for a piece of mind.
Honestly I wouldn't.

On average an i30 would complete say 100,000 km in the 5 year warranty period after that Hyundai are not concerned.
 

I hope better than that. We base our usage on 40,000km/yr ave. for at least 5 yrs!

SPman, like you we based our useage on 50,000K's per car per year,so hopefully Hy are well and truly willing to follow up on their warranty

Hi Hornet,
I will cut to the chase.I have a 2008 i30 crdi,the dealer has found "metallic fragments" in my injector pump.HYundai wont fix under warranty claiming "contaminated fuel".The dealer has been putting injector cleaner in at every 30k service.
I have done 120,000k in this vehicle(like my road trips!) and if I have or had "contaminated"
fuel I would certainly have noticed it at some stage, and the dealer would have heard about it.The car has never missed a beat.
I think I would be listening to your mechanic mate.

On googling and reading about metallic fragments in HPFPs it became obvious to me that there was a trend with what was being said. It generally came down to a lack of lubricity in the diesel fuel. Some mentioned the aftermath of inadvertently pumping some unleaded into a diesel tank and running for a bit before realising/siphoning etc....other sources mentioned poor batches of fuel.

I wrote an e-mail to a diesel specialist asking about optimum filtration of diesel fuel for a CRD system. He replied-
" I make no recommendations for any common rail system as they are inherently flawed in design because they have a gear pump on the 'clean' side of the system which makes small slivers of metal, as well as being prone to corrosion in the rail if any water gets into the system at all"

MMNnnnn...

Let us know the result of your situation, Hornet. I bet that a new/reconditioned HPFP will not be cheap....

I'd be real interested in Kom's thoughts on this matter. CRD is so popular, surely this "design flaw" would have been taken into consideration. All manufacturer's can't be wrong, surely.

What I posted on another site
I have asked Hy in an email for their advice on the use of this product (ChemTec) and will post the reply when I receive it. (soon I hope)

To date I have not received a reply and I think it would be unreasonable to expect one until Hy has had reasonable time to considered the effect of ChemTec on their CRDI engines and the warranty they give us.
Interesting to note that Hy has blamed "contaminated fuel" for faults to the fuel system components and then they avoid responsibility under their warranty. How could this be when Hy have used their injector cleaner on a regular basis and I assume replaced fuel filters with genuine items at service intervals.
Makes one question the value of the warranty provided and why I am paying  the high cost services Hy provide that I considered essential to protect my warranty. Depending on what happens I will consider moving away from dealer high cost servicing.

I have been considering this problem today.

The issue here is supposedly contaminated fuel in the fuel system components. Wrong.

Hy designed their fuel system with a fuel filter, they charge $100 to replace, when servicing. So if metal fragments can get past this filter, then their design is flawed and there are thousands of Diesels all over the world running the same filtering system. Therefore it should be warranty fix.

If the fragments are from the HPFP, which is after the fuel filter, then that is a design flaw and also a warranty repair. Either way, you should NOT be required to pay.

I agree entirely and  find Hyundai presumption rather odd,mind you they have not replied to my emails yet(8 working days).I have been excommunicated..lol..Great to see that they are A typical...
Oh well hopefully I can push a bit harder and they will replace the faulty component(s)...
