this is exactly what happens when you put in a 10w40 oil in a car which is designed for likes of 0w20 thinner oils. Its not suzukis fault but pakistanis hired by suzuki who never respond to my technical email and claims....they are pouring in 10w40 from assembly line to save cost which will surely result in claims.
also many people and dealerships dont know Alto takes in 2.6L engine oil with oil filter replacement. i have seen dealerships pouring in 3L and even 3.2L in the tiny engine....
kisi ko chankana nahi pata is gari ka pak suzuki mien. Jaahil hire kiyea hoye hain
