Maruti Suzuki has introduced its Ecstar range of lubricants, coolant, and car care products in India. The company says that Ecstar products have been rigorously tested on their cars and claims that Ecstar branded products (read engine oil, automatic transmission oil, etc.) can improve a car’s fuel efficiency by 3 per cent. Initially, the Ecstar range will only be sold through Nexa workshops. However, the company says it will soon introduce Ecstar products at all Maruti Suzuki service stations and in the aftermarket as well.
