Today i went for oil change
Presently i am using Liqui Moly 10W40 and its 1700 km driven
but shopkeeper told that oil may cover more 1000 km
but i will change at 2000 km
he offered me a bundle pack
he said that we are offering
1) chain treatment, (first we (they) will wash chain with petrol and then apply liquid that may last 1 year) according to shopkeeper
2) Before engine oil change, Engine Flush it with liquid chemical to Remove Sludge from engine
3) Fuel Additive used in petrol tank it contains chemical which remove Carbon from cylinder head and cleans Carburetor and its effect lasts 1000 Kms
4) Oil Additive used in Engine oil after engine flush with new oil it increases life of engine as it makes friction less and makes engine sound less
These are claims made by him
should i buy this package?
