I have alto vxr 2004 model, mileage is 100k, and I have recently changed oil and using Kixx 10w-40 API SJ grade oil. Previously I was using Zic Hiflo API SM oil, but after reading here on Pakwheels and After a senior Pakwheeler @saboor73 comments, that Old Alto Vxr F10a engine needs older grade oil (SG, SJ etc), I have switched the oil from Zic API SM to Kixx API SJ. Is this the right oil for my car now?
