I am planning to get the Oil changed now in the service. Apart from this do I also go for decarb and Throttle body cleaning/ Injector cleaning?

good time to get it done.

I have bought a UP Police disposal Gypsy, which had done 96K KMs. In all probability it's engine was never flushed or de-carbonized and God knows what was the frequency of oil change.

I recently gave it to Maruti Service Masters, Okhla for service. There I asked the SA to do engine flush and de-carbonization; and he recommended against it. His logic - in 96K KMs of use, a carbon layer must have formed in the engine, and pistons must be fitting snugly.

By flushing/de-carbonization, this layer will be washed off and a gap will appear between cylinder and piston.

I don't know whether he is giving me genuine advise or it is hogwash. What do you guys say about it?

Is getting a De-Carb done at an *** recommended or is it better to do it a place that is only in the job of de-carbonising?

Service adviser is true.. its not recommended to flush a high mileage engine.. if engine flush has not been done even once..This might lead to loss of compression, leaks etc..mainly because engine oil would have sealed worn parts and rubber seals.. which might leak if flushed.

Ok you could for the time being buy an additive called system G and put it in your tank and see how the car does. If the situation doesnt improve then goto any maruti autorised work shop and get it done. The cost would be close to 5-8k. This additive is avaiable at a few petrol pumps or other parts & car acc. shop.

My sugestion is to go for system G and then to go for a De-carb.

Cost of system G should be close to Rs. 250-300.

I got engine 3M engine decarbonizing done as part of service yesterday. The injector cleaning is also done apart from decarbonizing. Was seperate injector cleaning required as decarbonizing would have cleaned the injectors as well? The can used for decarbonizing mentions that it cleans injectors and valves along with the engine. I think they have used seperate fluids for both and seperate injector cleaning was unnecessary.

It was partially my mistake as I had asked them for injector cleaning without thinking about decarbonizing.

as far as I know if you request the ASC to give your car the "engine decarbonizing" treatment, this includes cleaning the Fuel Injectors too.

We have found this with our Tata Indica DLG Turbo V2 around 3 weeks ago and again with my Scorpio around 2 weeks ago.

Both the vehicles feel significantly better after the decarb treatment. no doubt about it.

Quite often they see you a decoke just to get some extra bucks. I must say that I have never gone in for a decoke - the maximum any car of mine has done has been 65,000km. Throttle body & Injector cleaning yes, decoke No.

The best decoke is a one hour high speed run on the highway!

Is decarb usually done using a engine flush or is the head actually opened and cleaned up?

For my "bike" I have had the manual de-carb done usually every 30K kms.

My Palio is now nearing 28K kms, there are no performance/mileage issues. Should I still go ahead with a decarb, or if something is running fine should I just let it be?

Any recommendations for places to get it done in Bangalore?

It is done using 3M flush. They provided the empty can as a proof of doing it . They do not do a manual decarb.

The pick up has improved after the service. I am not sure whether it can be attributed to the decarb. I went for it mainly as the pick up had decreased recently. I think you can leave it for a later date.

It is done at authorized service centres of Hyundai and Maruthi. I do not know where you can get it done for a Palio.

Hey Guys,

I got decarbonising done on my car when i bought it second hand, the Air intake valve had quiet a lot carbon deposits, I had to get it done and it is much better after i did the cleaning. I am now planning to get the fuel injectors cleaned, saw a few options like Sonax, which needs to be added to the fuel and the other way is to get the cleaning done by the injector cleaning machine, which when i checked with MASS and other mechanics, they quoted the cleaning charges to be around 475 per Injector (Mechanic quote), and MASS quoted 1800 for the 4 injectors. Not sure if it is really worth it.

I just want to keep the engine in top shape, I don't like being reactive, its rather better to be proactive, as the car in question is a used car done about 56k kms when bought.

Does the experts feel the price quoted is too much or is it reasonable?
