System G / D (IFTEX): yes or no????, Fuel additives thread.

[zen91]

System G + Unleaded petrol is a very good combination for Ford cars.You can make out the difference in the performance of the car instantly.

System D + normal diesel on Fiat cars is also a good combination.I have observed that the car now runs much smoother than before.

Purchased system D today evening. The tank had appx 30L diesel in it so poured 30ml of the additive. @250ml pack for 250 bucks. Got it from a BP bunk.
Lets c if there are any noticeable changes observed in the car.

Any kind of additive in my Indica Turbo reduces the acceleration noticeably. (At least I can notice it). I have tried Hi Speed, xtramile, turbojet and normal diesel with System D. It runs best on normal diesel. Hi speed has the least drop in acceleration and System D stinks up the exhaust.

Thats surprising, its part of TATA's recommended fuel additives for all their engines. No disclaimers here

teknophobia, thats funny, cos i noticed my engine running much smoother. acelleration, didnt notice so much

[teknophobia]

The engine does run smoother, however, acceleration suffers. I speak from experience. OT: Greenhorn, there are more pics in my garage, as you requested

live2drive : But in my IMO cleaning the injectors itself will have some positive effects on the car such as better spray pattern and i feel the emission levels will decrease.

If you want to try additives, and you have a Common Rail engine, then try something that is specifically marked for CRDi engines, like the one from Sonax.

hmm. the engine sounds very laid back even when acellerating hard. i thought it was because of the additive. didnt think of it from that angle.

PS: my mileage is much worse, 13ish :( ( not because of the additive - its been like that , always )

another doubt, will this become redundant if I use a better grade of lubricant, from the API CF4 castrol GTD to CI rated delvac MX ?

The ppl in-charge at Tata Motors workshop do not recomment System D for their Quadrajet engines. I was also told to use normal diesel & was recommended filling-up from HPCL pumps. When I insisted to know the reason for HPCL, I was informed with a smile that doing so would increase my efficiency in the long time.

Did you ask them for a Service bulletin or a formal notification ?? on this. I have seen Delphi (CRDI fuel injection supplier for TATA) recommending their own additives made in collaboration with Texaco/Chevron(same as System D) for all IDI/ DI engines in UK. Its a bit ironic.

Try using a light foot, you'll be amazed at the differnece it makes. Mine went up from 15ist to 17+ consistent after I started doing that. It might be the XM1s as well, I'm not completely certain.

For that matter, Tata does not even recommend premium diesel for their Dicor vehicles. (Note: this point is being discussed elsewhere, so let us only look at System-D here).

@Joe, if you filled in 15L of diesel, then the amount of System-D that you should have added would be : 15ml + 1ml for each liter of diesel that was already there in the tank. The engine needs to see 1ml of this addtive per litre of fuel. This could be what you have missed.

it is written that we should fill 1ml of additives with 1L of fuel. so when i filled 15l then 15ml is correct right. correct me if im wrong.

Where can i get sonax fuel additive in delhi/ncr?

joe angelo : it is written that we should fill 1ml of additives with 1L of fuel. so when i filled 15l then 15ml is correct right. correct me if im wrong.

so when you filled that 15L, was your tank empty ? or did it have any fuel in it ?

Pls re-read my prev post on this.

[joe angelo]

i almost filled up the tank with 15l when the fuel needle got below the red line. i almost filled up approx 17-18ml considering some litres of diesel inside.
