The Benz has been our regular highway steed for 7+ years now, and it's been filled up at unknown pumps in Goa, Mahabaleshwar, Deolali and more. At 80,000 kms, the car is still ticking away healthy

Yes, I did exercise due caution in choosing a pump that served (atleast, I hope) unadulterated diesel. Strictly no additives though.

Note : Unlike the body, the rest of the Benz isn't necessarily robust. But I haven't had a single issue related to filling up with regular diesel yet.

Hey, I was an Indigo owner till Jan 2012 and used only pure diesel (without additive). Can you explain the exact difference you felt after using System D?

Most car manufacturers ban any kind of fuel additive, especially for diesel engines.

I still remain a non-believer. All the problems that this product claims to solve have NEVER been experienced by me in 500,000 kms of diesel engine experience. So, what's in it for me? Would I take a cough syrup even when I haven't had a cough in 5 years?

Thats a choice one has to make, wait till cough catches on or take a preventive cough medicine because nobody can predict if you will or will not catch cough.

OT was from the perspective that this is not a generic additive thread discussion and could have been discussed in a generic thread(I shared) but anyway its a mod's decision so respect that.

Engine has definitely been smoother. Noticeable on the TDI /TCIC's.
The TDCi Ikon has not shown a visible/audible difference like the Tata's, though.

My Best ever FE on the Sumo was also with an additive - almost 14kmpl on highway. I was using Elf's EMDFA, with Reliance diesel. I currently get only about 12 with IOC & no additive

Done 100kms on it. Improvement seen after 50kms

- Engine's definitely smoother with consistent RPM
- Peppier pickup, Throttle response like never before
- No smoke on throttling(visibly)

My family and I follow some good advice from my paternal Uncle who is a surgeon - self medication is not a good thing, even if treated as prophylactics. Needless expense and the risk that the medicines could have unintended consequences. All this boils down to 'If it ain't broke don't fix it'

HOWEVER:

That's good feedback and something that some diesel powered vehicle owners may be interested in. Also, what do you mean by consistent RPM? Is it at idle? No smoke is a good change as well..my bro's Safari spewed black smoke like a railway steam loco when accelerating hard.

Its difficult to explain, its like the engine noise is consistent/smooth at idle. Dont know if thats a good definition.

Safari's dont smoke that much but yes I could see almost no visible smoke on throttling as almost all diesel engine smoke a bit upon throttling.

Also another noticable difference was shorter cranking while startups.

@dadu,

What is the ratio you have used?

Yes any diesel will smoke when pushed hard. However, my bro's safari was a 2002 model and the engine though capable of clocking some serious mileage and long lived wasn't very good - even though it was a diesel it consumed more than its expected of engine oil, spewed smoke and leaked oil thru the sump and the cam shaft cover as well. The pick up? It picked up like a passenger train. But once she was @ 70-80 kmph it was, well, like a proper diesel locomotive - unstoppable! Though it had all the normal Tata QA niggles that I positively hate experiencing - I loved that Safari and travelling in it.

I am sure Tata has made many changes to the vehicle including adding the DICOR mill. All of which should have made the engine better in terms of performance, smoothness, mileage etc.

dadu it would be interesting to know the benefits (or lack of them), issues etc over the medium to long term plus the overall cost.

I am sure some oil burner owners will keep a close eye on this thread.

@R2D2, will post after a tankful use.

Condor, where is this additive available in Bangalore?

There are two dealers. Check the service dealer link in the 1st post.

thats pretty much it. without it, the engine feels like a tractor. with it, its similar to the feeling you have immediately after an oil change

of course, if you dont feel a difference, I wouldnt recommend using it.

Tanks up and got 1.5 kmpl extra mileage with SPF i.e. with the extra benefits I quoted below & purely on a price point(based on extra KM's run) I am paying Rs10 for this additive.

- Engine's definitely smoother with consistent RPM
- Peppier pickup, Throttle response like never before
- No smoke on throttling(visibly)

Another thing I noticed is that I am downshifting the Gears much lesser(specially from 3rd & 4th), the engine is able to pick up momentum at higher gears itself.

Assuming you have used both systemD and this, which one would you rate as better in the mentioned parameters?

Yes, have used System D and now this. System D does not even talk about many areas which are covered by SPF for improving diesel performance.

SPF is definitely better, no doubt.
