Believe me or not, MY car is one of the best maintained safari as I used to change the engine oil in 3-4k interval and it never run without any additives. (I am the stupid who tested the efficiancies of the additives like IFTEX, Automax, MP6TY etc..) I have flushed the fuel system 2 times in the last 4 months. One with IFTEX and now with OWS 360.

And none of the additives removed the carbon deposits from my fuel injectors. If you are in chennai, I welcome you come the workshop to see my car. (it will be there 2 more days).

And regarding the Engine Flush OWS, it worked well. But believe me or not, NO ADDITIVES or Diesel or even ACIDs can remove the carbon 100% - we used two 18v Bosch drilling machines to clean the carbons!!!! But now I am wondering, how SYNTHETIC Oils will do its job 100%, if your oil bump, sump & strainer are like mine(after a Engine flush) - believe me or not I used new 15w40 Oil just for flushing - that means oil change just before the flush!!!!)!

No, this is not overhaul as my Engine is in perfect condition(only 60k done so far). Its De-Carbonization and I am paying only Rs. 5000 for the entire job including oil. I am doing it in my friends workshop.

I would say a very very professionally executed cleanup by your friend. Please post his contact details at the end for everyone to take advantage of his expertise and meticulate execution. Worth every penny spent.

Also is it possible to post pictures of the injectors, the fuel additives work mostly on the injectors and would want to see their condition too.

@ibm_jennifer,

Superb work done and thanks for the excellent photos you have posted. My GTX has done 65K kms and want to go for Fuel Injection System Cleaning, Throttle body cleaning and Engine Decarbonization. This service is offered in concorde motors bangalore, Anybody has done such work so far for a Palio 1.6?

Also want to know If I need to go for soft decarbonization/Hard decarbonization of the Engine, what is the difference and how effective it is to improve the performance?

The URL which talks about Decarb Services offered by tata motors is below.
Tata Motors Customer Care :: Decarbonising & Engine Flush

Am planning to leave the vehicle for service tomorrow and get these works done their. Any suggestions/ideas would be of great help for me

No, never go to Authorized workshops to do decarb. I have inquired to Concord about decarb works. They didnt even open the engine head. They just spray Bardhal S1 & S2 into the fuel system and run the car for 50 kms. Its 99% useless.

If your car is under warranty, you dont need to do any decarb. If your car is old, find a mechanic and ask him to do a Manual Decarb. If you are in Chennai, I will help you to do the decarb in my friends workshop.

Today we are going to fit the engine. (The delay is because we couldnt source a Metal Gasket(like SUMO Victa) for Safari Engine for 2 days in Chennai). I will update the pictures tomorrow.

Dont go to TASS for a Decarb work, Just try OWS 310 & 260. They may work.

Thanks for the brilliant pics. Truly an eye-opener.

Just a few days ago i added Nulon (PTFE Based additive) to my OHC on someone's recommendation. Absolutely no difference. And after reading about PTFE based additives on the net, im kicking myself on doing so. Lucky I did'nt do it while changing my oil, just midway. Will get a firsthand experience once I open up the oil filter during the next oil change.
My verdict, Waste of Rs 500.

PTFE is a Solid, Never add PTFE based additives with Engine Oil as it may block the oil circulation. If you really like NULON, you can add PTFE based additives in GearBox or Transmission Oil.

Not that i really like it or something, its just that it was recommended by someone who was quite knowledgeable about cars. At that time I did not get the time to check about the benefits online and took a can trusting his experience.

I had already done 4k in my current oil and would be changing it in another 1-2k so I thought what the heck, i'll add it now and even if it's no good, during the next oil change, its gonna get out of the system.

No problem, it will not kill your Engine, let it to be there.

Use Bardhal Oil treatment(detergent based) if your Engine is old(more than 50k) or use OWS 220 if your engine is New. Never use PTFE or Zinc based Additives like STP, NULON in the Engine.
